Desulfovibrio marrakechensis sp. nov., a 1,4-tyrosol-oxidizing, sulfate-reducing bacterium isolated from olive mill wastewater
A novel mesophilic sulfate-reducing bacterium, EMSSDQ4 T, was isolated from olive mill wastewater in the semi-arid region of Morocco (Marrakech). Cells were Gram-negative, catalase-positive, straight rods that were non-motile and non-spore-forming and contained cytochrome c 3 and desulfoviridin. The DNA G+C content was 65.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolate was a member of the genus Desulfovibrio with Desulfovibrio carbinoliphilus D41T, Desulfovibrio alcoholivorans SPSNT, Desulfovibrio fructosivorans JJT and Desulfovibrio carbinolicus EDK82T as the most closely related strains with validly published names. In addition to the classical substrates used by Desulfovibrio species, the isolate oxidized 1,4-tyrosol, one of the most abundant phenolic compounds occurring in olive mill wastewater, to 4-hydroxyphenylacetate without ring cleavage. D. alcoholivorans SPSNT was also found to carry out this reaction. Under air, strain EMSSDQ4 T exhibited limited growth on lactate and yeast extract in the absence of sulfate. On the basis of genotypic and phenotypic characteristics, it is proposed that the isolate represents a novel species, Desulfovibrio marrakechensis sp. nov. The type strain is EMSSDQ4 T (=DSM 19337T =ATCC BAA-1562T).

Lysobacter panaciterrae sp. nov., isolated from soil of a ginseng field
More LessA Gram-negative, aerobic, rod-shaped, non-spore-forming bacterial strain, designated Gsoil 068T, was isolated from soil of a ginseng field in Pocheon Province (South Korea), and was characterized to determine its taxonomic position by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain Gsoil 068T belonged to the family Xanthomonadaceae, class Gammaproteobacteria, and was related most closely to Lysobacter brunescens ATCC 29482T and Lysobacter gummosus ATCC 29489T (96.1 % sequence similarity). The G+C content of the genomic DNA of strain Gsoil 068T was 67.0 mol%. The detection of a quinone system with ubiquinone Q-8 as the predominant component and a fatty acid profile with iso-C15 : 0, iso-C17 : 1 ω9c, iso-C17 : 0 and iso-C11 : 0 3-OH as the major components supported the affiliation of strain Gsoil 068T to the genus Lysobacter. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 068T is considered to represent a novel species of the genus Lysobacter, for which the name Lysobacter panaciterrae sp. nov. is proposed. The type strain is Gsoil 068T (=KCTC 12601T =DSM 17927T).

Parvularcula lutaonensis sp. nov., a moderately thermotolerant marine bacterium isolated from a coastal hot spring
Strain CC-MMS-1T, a motile, Gram-negative, orange-pigmented bacterium, was isolated from water samples collected from a rare coastal hot spring at Lutao, an island off the eastern coast of Taiwan. 16S rRNA gene sequence studies showed that the novel strain was closely related to Parvularcula bermudensis HTCC2503T (95.1 % sequence similarity). The fatty acid profile was slightly different from P. bermudensis HTCC2503T. The results of physiological and biochemical tests allowed clear phenotypic differentiation of the novel isolate from P. bermudensis HTCC2503T. It is evident from the genotypic and phenotypic data that the strain should be classified as a novel species in the genus Parvularcula. The name proposed for this taxon is Parvularcula lutaonensis sp. nov. The type strain is CC-MMS-1T (=BCRC 17814T=KCTC 22245T).

Nitratireductor kimnyeongensis sp. nov., isolated from seaweed
More LessAn aerobic, Gram-negative, catalase-positive, oxidase-positive bacterium was isolated from a dried seaweed sample collected from Kimnyeong Beach in Jeju, Republic of Korea. The cells of the organism, designated strain KY 101T, were rods (0.4–0.5×1.2–2.7 μm) and motile by means of flagella. The colonies of the cells were 0.5–1 mm in diameter, smooth, circular, convex and light yellow in colour. The isolate showed growth at 10–40 °C, pH 6.1–12.1 and in the presence of 7 % NaCl. The major fatty acid was summed feature C18 : 1 ω7c/C18 : 1 ω9c/C18 : 1 ω12t and the DNA G+C content was 60.4 mol%. 16S rRNA gene sequence studies showed that the organism was phylogenetically related to the family Phyllobacteriaceae, with Nitratireductor aquibiodomus (99.1 % sequence similarity) as the closest neighbour. The level of DNA–DNA relatedness between strain KY 101T and N. aquibiodomus DSM 15645T was 18.4–23.2 % (duplicate measurements). The combination of phenotypic differences and DNA–DNA hybridization data supports the suggestion that the isolate represents a novel species of the genus Nitratireductor, for which the name Nitratireductor kimnyeongensis sp. nov. is proposed. The type strain is strain KY 101T (=KACC 11904T=JCM 14851T).

Aquitalea denitrificans sp. nov., isolated from a Korean wetland
A novel bacterium, designated strain 5YN1-3T, was isolated from wetland peat collected from Yongneup, Korea. The bacterium was facultatively anaerobic, Gram-negative, yellow-coloured, rod-shaped, mesophilic and motile with one polar flagellum. The strain grew optimally at 30 °C, at pH 6.0–9.0 and with 0–1 % NaCl (w/v). 16S rRNA gene sequence analysis showed the highest similarity to the sequence from Aquitalea magnusonii TRO-001DR8T, with 98.7 % sequence similarity. However, strain 5YN1-3T showed DNA–DNA relatedness of 43 % (40 % in a reciprocal experiment) with A. magnusonii LMG 23054T. The strain contained summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1 ω7c) and C16 : 0 as major cellular fatty acids. On the basis of DNA–DNA relatedness and physiological and biochemical characterization, strain 5YN1-3T should be assigned to a novel species of the genus Aquitalea, for which the name Aquitalea denitrificans sp. nov. is proposed. The type strain is 5YN1-3T (=KACC 12729T =DSM 21300T).

Providencia sneebia sp. nov. and Providencia burhodogranariea sp. nov., isolated from wild Drosophila melanogaster
More LessMultiple isolates of the genus Providencia were obtained from the haemolymph of wild-caught Drosophila melanogaster fruit flies. Sixteen isolates were distinguished from the six previously described species based on 16S rRNA gene sequences. These isolates belonged to two distinct groups, which we propose each comprise previously undescribed species. Two isolates, designated AT and BT, were characterized by DNA sequences of the fusA, lepA, leuS, gyrB and ileS housekeeping genes, whole-genome DNA–DNA hybridizations with their nearest relatives and utilization of substrates for metabolism. The closest phylogenetic relatives of strain AT are strain BT (86.9 % identity for the housekeeping genes) and Providencia stuartii DSM 4539T (86.0 % identity). The closest phylogenetic relatives of strain BT are strain AT (86.9 % identity) and P. stuartii DSM 4539T (86.6 % identity). The type strains of described species in this genus shared between 84.1 and 90.1 % identity for these sequences. DNA–DNA hybridization between the strain pairs AT–BT, AT–P. stuartii DSM 4539T and BT–P. stuartii DSM 4539T all resulted in less than 25 % relatedness. In addition, patterns of utilization of amygdalin, arbutin, aesculin, salicin, d-sorbitol, trehalose, inositol, d-adonitol and d-galactose distinguish strains AT and BT from other members of this genus. Strains AT and BT therefore represent novel species, for which the names Providencia sneebia sp. nov. (type strain AT =DSM 19967T =ATCC BAA-1589T) and Providencia burhodogranariea sp. nov. (type strain BT =DSM 19968T =ATCC BAA-1590T) are proposed.

Roseovarius pacificus sp. nov., isolated from deep-sea sediment
More LessAn aerobic, Gram-negative, ovoid to rod-shaped bacterial isolate, strain 81-2T, was isolated from deep-sea sediment of the Western Pacific Ocean. Strain 81-2T was motile, formed faint pink colonies, and was catalase-positive, weakly positive for oxidase and required NaCl for growth. It did not synthesize bacteriochlorophyll a and its DNA G+C content was 62.3 mol%. The 16S rRNA gene sequence of strain 81-2T indicated that it was a member of the Roseobacter clade of the class Alphaproteobacteria, with moderate bootstrap support for inclusion in the genus Roseovarius. Its closest phylogenetic neighbour was the type strain of Roseovarius nubinhibens, which shared 95.8 % 16S rRNA gene sequence similarity; strain 81-2T was <95.0 % similar to strains of other related species and genera. Phenotypic, chemotaxonomic and phylogenetic data support assignment of this strain to the genus Roseovarius as a representative of a novel species. The name Roseovarius pacificus sp. nov. is proposed, with strain 81-2T (=MCCC 1A00293T=CGMCC 1.7083T=LMG 24575T) as the type strain.

Novel Campylobacter lari-like bacteria from humans and molluscs: description of Campylobacter peloridis sp. nov., Campylobacter lari subsp. concheus subsp. nov. and Campylobacter lari subsp. lari subsp. nov.
More LessA polyphasic study was undertaken to clarify the taxonomic position of Campylobacter lari-like strains isolated from shellfish and humans. The diversity within the strain collection was initially screened by means of fluorescent amplified fragment length polymorphism analysis and whole-cell protein electrophoresis, revealing the existence of two clusters distinct from C. lari and other Campylobacter species. The divergence of these clusters was confirmed by phenotypic analysis and by 16S rRNA and hsp60 gene sequence analysis. Phylogenetic analysis identified C. lari, Campylobacter jejuni, Campylobacter coli and Campylobacter insulaenigrae as the closest phylogenetic neighbours of both taxa. DNA–DNA hybridizations revealed that one cluster, comprising 10 strains, represented a novel Campylobacter species, for which the name Campylobacter peloridis sp. nov. is proposed, with 2314BVAT (=LMG 23910T =CCUG 55787T) as the type strain. The second cluster, comprising six strains, represents a novel subspecies within the species C. lari, for which the name Campylobacter lari subsp. concheus subsp. nov. is proposed, with 2897RT (=LMG 21009T =CCUG 55786T) as the type strain. The description of C. lari subsp. concheus has the effect of automatically creating the subspecies Campylobacter lari subsp. lari subsp. nov. (type strain LMG 8846T=NCTC 11352T).

Rhodobacter aestuarii sp. nov., a phototrophic alphaproteobacterium isolated from an estuarine environment
More LessAn ovoid to rod-shaped, phototrophic, purple non-sulfur bacterium was isolated from a brown-coloured microbial mat from the brackish water of Bhitarkanika mangrove forest, Dangmal, Orissa, India. Cells of strain JA296T were Gram-negative and motile, forming chains of four to eight cells. The colour of the cell suspension grown under anaerobic conditions in the light was yellowish green. Bacteriochlorophyll a and the carotenoids spheroidene and spheroidenone of the spirilloxanthin series were present as photosynthetic pigments. The bacterium was a facultative anaerobe and was able to grow photo-organoheterotrophically and chemo-organoheterotrophically. Thiamine was required as a growth factor. C18 : 1 ω7c was the dominant fatty acid. Internal cytoplasmic membranes were of the vesicular type. Strain JA296T did not require NaCl for growth. Phylogenetic analysis on the basis of 16S rRNA gene sequences showed that strain JA296T was most closely related to Rhodobacter capsulatus ATCC 11166T (95.5 % sequence similarity) and clustered with species of the genus Rhodobacter of the family Rhodobacteraceae, class Alphaproteobacteria. On the basis of 16S rRNA gene sequence analysis and morphological and physiological characteristics, strain JA296T represents a novel species of the genus Rhodobacter, for which the name Rhodobacter aestuarii sp. nov. is proposed; the type strain is JA296T (=JCM 14887T =CCUG 55130T).

Donghicola xiamenensis sp. nov., a marine bacterium isolated from seawater of the Taiwan Strait in China
More LessA Gram-negative, ovoid rod-shaped bacterium that lacked bacteriochlorophyll a, designated strain Y-2T, was isolated from seawater of the Taiwan Strait, China. The strain was oxidase- and catalase-positive, and reduced nitrate to nitrite. Optimal growth occurred at around pH 7.0 and 25 °C in the presence of 1–3 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain Y-2T belonged to the class Alphaproteobacteria and formed a coherent cluster with Donghicola eburneus SW-277T (96.2 % sequence similarity). The major whole-cell fatty acid was C18 : 1 ω7c (75.42 %). Other characteristic fatty acids were C18 : 0 (9.16 %) and C16 : 0 (7.32 %). The DNA G+C content of strain Y-2T was 62.4 mol%. Therefore, based on phenotypic properties, phylogeny and genomic data, strain Y-2T should be placed in the genus Donghicola as representing a novel species, for which the name Donghicola xiamenensis sp. nov. is proposed. The type strain is Y-2T (=MCCC 1A00107T=LMG 24574T=CGMCC 1.7081T).

Oceanicola pacificus sp. nov., isolated from a deep-sea pyrene-degrading consortium
A taxonomic study was carried out on a Gram-negative, rod-shaped, non-motile, halophilic bacterium, designated strain W11-2BT, which was isolated from a pyrene-degrading consortium that was enriched from sediment from the Pacific Ocean. Growth was observed at salinities of 0.5–10 % and at temperatures of 10–41 °C. Strain W11-2BT was unable to degrade Tween 80 or gelatin. 16S rRNA gene sequence comparisons showed that strain W11-2BT was related most closely to Oceanicola nanhaiensis SS011B1-20T (95.8 % similarity) and Oceanicola batsensis HTCC2597T (95.7 %); levels of 16S rRNA gene sequence similarity between strain W11-2BT and the type strains of other species tested were below 95.2 %. The dominant fatty acids of strain W11-2BT were C18 : 1 ω7c (32.1 % of the total), C19 : 0 cyclo (20.9 %), C18 : 1 ω7c 11-methyl (19.5 %), C18 : 0 (7.3 %), C17 : 0 (6.6 %) and C16 : 0 (3.8 %). The G+C content of the chromosomal DNA was 64.6 mol%. The above data were in good agreement with those of members of the genus Oceanicola. Based on morphology, physiology, fatty acid composition and 16S rRNA gene sequence data, strain W11-2BT is considered to represent a novel species of the genus Oceanicola, for which the name Oceanicola pacificus sp. nov. is proposed. The type strain is W11-2BT (=CCTCC AB 208224T=LMG 24619T=MCCC 1A01034T).

Marinobacterium nitratireducens sp. nov. and Marinobacterium sediminicola sp. nov., isolated from marine sediment
More LessTwo strains, CN44T and CN47T, isolated from marine sediment of the East China Sea, were characterized by using a polyphasic approach. The isolates were Gram-negative, strictly aerobic, non-spore-forming rods. The chemotaxonomic characteristics of these isolates included the presence of C18 : 1 ω7c, C16 : 0, iso-C15 : 0 2-OH and/or C16 : 1 ω7c and C10 : 0 3-OH as the major cellular fatty acids and Q-8 as the predominant ubiquinone. The DNA G+C contents of strains CN44T and CN47T were 62.5 and 56.3 mol%, respectively. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain CN44T was related to members of the genus Marinobacterium. The most closely related described organism was the type strain of Marinobacterium rhizophilum (95.3 % sequence similarity). Strain CN47T showed the highest sequence similarity to the type strain of Marinobacterium stanieri (97.8 %) and <97 % similarity to other type strains of described Marinobacterium species. The level of DNA–DNA relatedness between strain CN47T and M. stanieri DSM 7027T was 46 %. On the basis of phenotypic and genotypic properties, strains CN44T and CN47T represent two novel species within the genus Marinobacterium, for which the names Marinobacterium nitratireducens sp. nov. (type strain, CN44T =CGMCC 1.7286T =JCM 15523T) and Marinobacterium sediminicola sp. nov. (type strain, CN47T =CGMCC 1.7287T =JCM 15524T) are proposed.

Sphingomonas japonica sp. nov., isolated from the marine crustacean Paralithodes camtschatica
More LessA Sphingomonas-like bacterium, strain KC7T, was isolated from a marine crustacean specimen obtained from the Sea of Japan and subjected to a polyphasic study. Comparative 16S rRNA gene sequence analysis positioned the novel strain in the genus Sphingomonas as an independent lineage adjacent to a subclade containing Sphingomonas trueperi LMG 2142T, Sphingomonas pituitosa EDIVT and Sphingomonas azotifigens NBRC 15497T. Strain KC7T shared highest 16S rRNA gene sequence similarity (96.1 %) with S. trueperi LMG 2142T, Sphingomonas dokdonensis DS-4T and S. azotifigens NBRC 15497T; similarities to strains of other recognized Sphingomonas species were lower (96.0–93.9 %). The strain contained sphingoglycolipid and the predominant fatty acids were C16 : 1, C16 : 0 and C18 : 1; 2-OH C14 : 0 was the major 2-hydroxy fatty acid. Previously, these lipids have been found to be characteristic of members of the genus Sphingomonas sensu stricto. On the basis of phylogenetic analysis and physiological and biochemical characterization, strain KC7T represents a novel species of the genus Sphingomonas, for which the name Sphingomonas japonica sp. nov. is proposed. The type strain is KC7T (=KMM 3038T =NRIC 0738T =JCM 15438T).

Haliea rubra sp. nov., a member of the Gammaproteobacteria from the Mediterranean Sea
More LessA novel aerobic, Gram-negative bacterium, designated strain CM41_15aT, was isolated from the surface of coastal waters of the north-western Mediterranean Sea. Cells were non-motile straight rods that formed red colonies on marine agar medium. The G+C content of the genomic DNA was 65 mol %. Phylogenetic analysis of the 16S rRNA gene sequence placed the strain in the genus Haliea within the class Gammaproteobacteria. On the basis of the 16S rRNA gene sequence comparison and physiological and biochemical characteristics, strain CM41_15aT represents a novel species, for which the name Haliea rubra sp. nov. is proposed. The type strain is CM41_15aT (=DSM 19751T=CIP 109758T=MOLA 104T).

Transfer of Teichococcus ludipueritiae and Muricoccus roseus to the genus Roseomonas, as Roseomonas ludipueritiae comb. nov. and Roseomonas rosea comb. nov., respectively, and emended description of the genus Roseomonas
More LessPhylogenetic analyses based on 16S rRNA gene sequences revealed that Teichococcus ludipueritiae and Muricoccus roseus are closely related to the species of the genus Roseomonas. The type strain of Teichococcus ludipueritiae, 170/96T, exhibited 16S rRNA gene sequence similarity levels of 96.4 % to Roseomonas cervicalis ATCC 49957T, 95.0 % to Roseomonas aquatica TR53T, 94.5 % to Muricoccus roseus 173/96T, 93.4 % to Roseomonas mucosa ATCC BAA-692T and 93.5 % to Roseomonas gilardii subsp. gilardii ATCC 49956T, while Muricoccus roseus 173/96T showed 16S rRNA gene sequence similarity values of 95.7 % to R. mucosa ATCC BAA-692T, 95.7 % to R. aquatica TR53T and 95.3 % to R. gilardii subsp. gilardii ATCC 49956T and R. gilardii subsp. rosea ATCC BAA-691T. Different phylogenetic analysis methods (neighbour-joining, maximum-likelihood and maximum-parsimony) confirmed that both species are within the Roseomonas branch. Neither polyamine patterns (spermidine predominant) nor major characteristics in the polar lipid profiles distinguished the two species from representatives of the genus Roseomonas. The fatty acid composition of the two species exhibited alphaproteobacterial characteristics but, like Roseomonas species, they also showed considerable amounts of the rarely encountered C18 : 1 2-OH. On the other hand, they showed some phenotypic differences, but their features are compatible with the transfer of these two species to the genus Roseomonas. We propose the reclassification of Teichococcus ludipueritiae and Muricoccus roseus as Roseomonas ludipueritiae comb. nov. (type strain 170/96T =CIP 107418T =DSM 14915T) and Roseomonas rosea comb. nov. (type strain 173/96T =CIP 107419T =DSM 14916T), respectively. Emended descriptions of the genus Roseomonas and the species Roseomonas gilardii (and its subspecies Roseomonas gilardii subsp. gilardii and Roseomonas gilardii subsp. rosea), Roseomonas aquatica, Roseomonas cervicalis, Roseomonas mucosa and Roseomonas lacus are provided.

Phaeobacter caeruleus sp. nov., a blue-coloured, colony-forming bacterium isolated from a marine electroactive biofilm
More LessThree isolates (LMG 24369T, LMG 24370 and R-26156) obtained from a marine electroactive biofilm that was grown on a cathodically polarized electrode were investigated by using a polyphasic taxonomic approach. Whole-cell fatty acid methyl ester and 16S rRNA gene sequence analyses indicated that the isolates were members of the genus Phaeobacter, class Alphaproteobacteria. Genotypic and phenotypic analyses demonstrated that the three isolates represent a novel species of the genus Phaeobacter, for which the name Phaeobacter caeruleus sp. nov. is proposed. The type strain is LMG 24369T (=CCUG 55859T). The DNA G+C content of strain LMG 24369T is 63.6 mol%.

Wickerhamomyces queroliae sp. nov. and Candida jalapaonensis sp. nov., two yeast species isolated from Cerrado ecosystem in North Brazil
Two novel yeast species, Wickerhamomyces queroliae sp. nov. and Candida jalapaonensis sp. nov., were isolated, respectively, from larvae of Anastrepha mucronata (Diptera: Tephritidae) collected from ripe fruit of Peritassa campestris (‘Bacupari’, Hippocrateaceae) and from flowers of Centropogon cornutus (Campanulaceae) in the Cerrado ecosystem of the state of Tocantins, Brazil. Analysis of the D1/D2 large-subunit rRNA gene sequences placed W. queroliae in the Wickerhamomyces clade near Wickerhamomyces ciferri and Candida silvicultrix. Candida jalapaonensis belongs to the Wickerhamiella clade and is related to Candida drosophilae. The type strain of Wickerhamomyces queroliae is UFMG-05-T200.1T (=CBS 10936T=NRRL Y-48478T) and the type strain of Candida jalapaonensis is UFMG-03-T210T (=CBS 10935T=NRRL Y-48477T).

Through morphological and physiological analysis as well as a molecular phylogenetic analysis based on the 26S rRNA gene D1/D2 region and internal transcribed spacer (ITS), this strain, which forms a clade with Candida vartiovaarae and a teleomorphic species, Williopsis saturnus, was revealed to represent a novel species in the genus Candida. The name Candida mengyuniae sp. nov. (type strain JHLT=CGMCC 2.3681T=CBS 10845T) is proposed for this novel species.

Delimitation of the species of the Debaryomyces hansenii complex by intron sequence analysis
More LessThe delineation of species among strains assigned to Debaryomyces hansenii was examined using a gene genealogies-based approach in order to compare spliceosomal intron sequences found in four housekeeping genes (ACT1, TUB2, RPL31 and RPL33). This revealed four distinct groups of strains containing, respectively, D. hansenii var. hansenii CBS 767T, D. hansenii var. fabryi CBS 789T, Candida famata var. flareri CBS 1796T (the anamorph of D. hansenii var. fabryi CBS 789T) and Debaryomyces tyrocola CBS 766T, whose species status was no longer accepted. The sequence divergence between these groups, reaching in some cases over 20 %, unambiguously isolated the groups as separate taxa, leading to a proposal for the reinstatement of the originally described species D. hansenii CBS 767T and D. tyrocola CBS 766T. The variety D. hansenii var. fabryi was further subdivided into two taxa, Debaryomyces fabryi CBS 789T and Candida flareri CBS 1796T (previously C. famata var. flareri and Blastodendrion flareri). The comparison of intron sequences therefore exposed cryptic species whose phenotypic traits are not distinguishable from known species, but which have significantly diverged from the genetic point of view. Hence, we describe the new taxon Debaryomyces macquariensis sp. nov. CBS 5571T is related to, but clearly distinct from, the Debaryomyces species mentioned above. The approach used in this work has also revealed the existence of populations within the newly delineated species D. hansenii and genetic exchanges between these populations, indicating an unexpected genetic diversity within this part of the genus Debaryomyces.

Legitimacy is an essential concept of the International Code of Nomenclature of Prokaryotes – a major revision of the Code is called for
More LessTindall [Int J Syst Evol Microbiol 58 (2008), 1979–1986] claimed that the International Code of Nomenclature of Prokaryotes (the Code) creates a paradox in the application of the term ‘legitimate’ in relation to valid publication, that the term is dispensable and that the paradox would be resolved by revising the Code to avoid its use. Although it is not clearly explained in the Code, the concept of legitimacy is central to the proposal of names. Discarding the concept would fundamentally alter the conceptual structure of the Code and obscure significant distinctions in formal nomenclature. The text of the Code itself is not clear and a careful reading suggests that it would be enhanced by a critical overview involving textual revision and restructuring of some sections. The Judicial Commission is asked not to accept Tindall's suggested revision and it is proposed that the Editorial Board of the International Committee on Systematics of Prokaryotes re-examine the Code from first principles and make such revisions as will avoid in future the confusion, ambiguities and uncertainties indicated here.
