Vagococcus elongatus sp. nov., isolated from a swine-manure storage pit
More LessA polyphasic taxonomic study was performed on an uncharacterized Gram-positive, catalase-negative, elongated coccus-shaped bacterium isolated from a swine-manure storage pit. The bacterium, designated strain PPC9T, was facultatively anaerobic and had a DNA G+C content of 44.5 mol%. Comparative 16S rRNA gene sequencing indicated that the bacterium represented a novel subline within the genus Vagococcus, close to but distinct from Vagococcus lutrae. Strain PPC9T was readily distinguished from the five recognized species of the genus Vagococcus by using biochemical tests and molecular genetic analysis. Based on phylogenetic and phenotypic evidence strain PPC9T is considered to represent a novel species of the genus Vagococcus, for which the name Vagococcus elongatus sp. nov. is proposed. The type strain is PPC9T (=CCUG 51432T=NRRL B-41357T).

Alkalibacillus silvisoli sp. nov., an alkaliphilic moderate halophile isolated from non-saline forest soil in Japan
More LessTwo alkaliphilic, moderately halophilic bacteria, designated BM2T and HN2, were isolated from non-saline forest soil in Japan. The cells of strain BM2T were motile, aerobic, rod-shaped and Gram-positive. The peptidoglycan was of the A1γ type, and the diamino acid was meso-diaminopimelic acid. Growth was observed at NaCl concentrations between 5.0 and 25.0 % (w/v) (the optimum being 10.0–15.0 %, w/v), at pH 7.0–10.0 (optimum, pH 9.0–9.5) and at 20–50 °C. The predominant isoprenoid quinone was MK-7. The major cellular fatty acids were iso-C15 : 0 and anteiso-C17 : 0. The G+C content of total DNA of strain BM2T was 37.0 mol%. Phylogenetic analysis of the 16S rRNA gene sequence showed that strain BM2T was most closely related to Alkalibacillus haloalkaliphilus DSM 5271T (98.0 % sequence similarity). DNA–DNA hybridization results indicated low levels of relatedness between strain BM2T and A. haloalkaliphilus JCM 12303T (23 and 16 % reciprocally), Alkalibacillus filiformis JCM 13893T (25 and 21 %) and Alkalibacillus salilacus JCM 13894T (27 and 19 %). On the basis of the phylogenetic and phenotypic characteristics, strain BM2T represents a novel species, for which the name Alkalibacillus silvisoli sp. nov. is proposed. The type strain is BM2T (=JCM 14193T=DSM 18495T).

Gracilibacillus boraciitolerans sp. nov., a highly boron-tolerant and moderately halotolerant bacterium isolated from soil
More LessA motile, Gram-positive, boron-tolerant and moderately halotolerant rod-shaped bacterium was isolated from a soil naturally high in boron minerals found in the Hisarcik area of Turkey. The novel isolate, designated T-16XT, produced spherical or ellipsoidal endospores in a non-bulging or slightly swollen sporangium in a terminal position and survived in a medium containing up to 450 mM boron. Whereas it tolerated 11 % (w/v) NaCl, it also grew without NaCl or boron. The temperature range for growth was 16–37 °C (optimum 25–28 °C) and the pH range for growth was 6.0–10.0 (optimum pH 7.5–8.5). The DNA G+C content was 35.8 mol% and the major cellular fatty acids were iso-C15 : 0 and anteiso-C15 : 0 at 18.2 and 45.7 % of the total fatty acids, respectively. MK-7 (90 %) was the predominant respiratory quinone system and meso-diaminopimelic acid was the predominant diamino acid of the cell-wall peptidoglycan. Phylogenetic analysis of the 16S rRNA gene sequence revealed that the novel strain is closely related to the type strains of Gracilibacillus orientalis (96.7 % similarity), G. halotolerans (95.5 %) and G. dipsosauri (95.4 %). However, the maximum DNA hybridization value for this strain with these closely related strains was less than 26.2 %. On the basis of 16S rRNA gene sequence data and chemotaxonomic and physiological features, the organism T-16XT (=DSM 17256T=IAM 15263T=ATCC BAA-1190T) is proposed to be a member of the genus Gracilibacillus as the type strain of the novel species Gracilibacillus boraciitolerans sp. nov.

Lactobacillus composti sp. nov., a lactic acid bacterium isolated from a compost of distilled shochu residue
More LessTwo strains of lactic acid bacteria, strains NRIC 0689T and NRIC 0690, were isolated from a compost of distilled shochu residue in Japan. The isolates showed quite low sequence similarity to known species of lactic acid bacteria on the basis of 16S rRNA gene sequence; the highest sequence similarities to NRIC 0689T were shown by the type strains of Lactobacillus satsumensis, L. plantarum, L. hilgardii, L. buchneri and L. parabuchneri (92.9, 92.9, 92.8, 92.6 and 92.5 %, respectively). The isolates formed a distinct subcluster in the Lactobacillus casei–Pediococcus phylogenetic cluster. Levels of DNA–DNA relatedness revealed that the isolates belonged to the same taxon. Therefore, the isolates represent a novel species, for which the name Lactobacillus composti sp. nov. is proposed. The type strain is NRIC 0689T (=JCM 14202T=DSM 18527T).

Paenibacillus zanthoxyli sp. nov., a novel nitrogen-fixing species isolated from the rhizosphere of Zanthoxylum simulans
More LessFive endospore-forming, nitrogen-fixing strains were isolated from rhizosphere soils of Zanthoxylum simulans planted in Beijing, China. Phylogenetic analysis based on full-length 16S rRNA gene sequences revealed that the five strains formed a distinct cluster within the genus Paenibacillus. High levels of 16S rRNA gene sequence similarity were found between these novel strains and Paenibacillus azotofixans ATCC 35681T (97.8–98.5 % similarity) and Paenibacillus stellifer DSM 14472T (95.4–96.3 %). Levels of 16S rRNA gene sequence similarity between the novel isolates and other species of the genus Paenibacillus were less than 95.0 %. Levels of 16S rRNA gene sequence similarity among the isolates were more than 98.0 %. DNA–DNA relatedness between the five novel isolates and P. azotofixans ATCC 35681T was 45.50–47.45 % and relatedness among the five novel strains was 95.8–99.6 %. A significant feature of the novel strains that differentiated them from P. azotofixans and other Paenibacillus species was that none of the novel strains could produce acid or gas from the following various carbohydrates: glucose, sucrose, lactose, fructose, glycerol, xylose, maltose, d-sorbitol, sodium succinate, sodium citrate, glycine or l-aspartate. Anteiso-branched C15 : 0 was the major fatty acid component (36.59 %) of novel strain JH29T. On the basis of phenotypic properties, 16S rRNA gene sequences, DNA G+C content, DNA–DNA hybridization, chemotaxonomic properties and the nifH gene sequence, the five novel strains form a very homogeneous group which is different from other related species within the genus Paenibacillus. Therefore, the five novel strains are considered to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus zanthoxyli sp. nov. is proposed. The type strain is JH29T (=CCBAU 10243T=DSM 18202T).
