Strain TS-56T was isolated from the gut of a wood-feeding termite, Reticulitermes chinensis Snyder. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the strain represented a member of the genus Gryllotalpicola of the family Microbacteriaceae , with sequence similarities to other species of the genus ranging from 96.6 % to 97.8 %. The isolate was Gram-stain-positive, non-motile, with light yellow colonies and irregular short rod-shaped cells (0.4–0.6 µm in diameter, 0.6–1.0 µm in length). Growth of TS-56T occurred at 20–35 °C (optimum, 30 °C) and at pH 4.0–8.0 (optimum, pH 5.0). The peptidoglycan of TS-56T contained ornithine, glutamic acid, alanine, homoserine and glycine. The acyl type was acetyl. The most abundant cellular fatty acid of TS-56T was cyclohexyl-C17 : 0 (88.79 %). The respiratory menaquinone was MK-11. The polar lipid profile contained disphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylinositol and two unknown glycolipids. DNA of the type strain had a G+C content of 67.4 mol%. On the basis of the phylogenetic properties and phenotypic distinctiveness, TS-56T represents a novel species of the genus Gryllotalpicola , for which the name Gryllotalpicola reticulitermitis sp. nov. is proposed. The type strain is TS-56T ( = CGMCC 1.10363T = NBRC 109838T).
A strain of a species of the genus Corynebacterium , designated AJ 3170T, was isolated during the 1980s from putrefied bananas. Since then, there have been no further updates on the description of the strain or its phylogenetic classification. However, phylogenetic analysis of this strain using 16S rRNA and in silico DNA–DNA hybridization has confirmed that it is a member of the genus Corynebacterium and that strain AJ 3170T clusters with Corynebacterium variabile DSM 44702T, Corynebacterium terpenotabidum Y-11T and Corynebacterium nuruki S6-4T in one subgroup. Furthermore, a combination of enzymatic, chemical, and morphological characterization techniques was applied in order to describe strain AJ 3170T further. The strain grew well at pH values of 6–10 and at temperatures of 30–41 °C. The major fatty acids were C16 : 0 (42.15 %), C18 : 1ω9c (41.6 %) and C18 : 0 10-methyl (TBSA) (8.56 %). The whole-cell sugars were determined to comprise galactose, arabinose and ribose. On the basis of this phenotypic, chemotaxonomic and phylogenetic characterization, it is proposed that strain AJ 3170T represents a novel species, for which the name Corynebacterium glyciniphilum sp. nov. is proposed; the type strain is AJ 3170T ( = DSM 45795T = ATCC 21341T).
A novel actinomycete, designated strain CA15-2T, was isolated from a soil sample collected from the rhizosphere of tamarisk in the Lop Nor region, Xinjiang, China, and was characterized by using a polyphasic taxonomic approach. Optimal growth occurred at 37 °C and pH 7.5–8.0 and with 5 % (w/v) NaCl. Strain CA15-2T formed white to pale-yellow branched substrate mycelium without fragmentation and sparse aerial mycelium with wavelike curves. Whole-cell hydrolysates of the isolate contained meso-diaminopimelic acid as the diagnostic diamino acid of the cell wall but no diagnostic sugars. The polar lipids comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylmethylethanolamine, phosphatidylethanolamine, one unidentified glycolipid, one unidentified phospholipid and other unidentified lipids. MK-9(H8), MK-10(H8) and MK-10(H6) were the predominant menaquinones. The major fatty acids were iso-C16 : 0 and C16 : 0. The G+C content of the genomic DNA was 69.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CA15-2T formed a distinct subclade in the family Nocardiopsaceae , with less than 95 % 16S rRNA gene sequence similarity to all known members of the family Nocardiopsaceae . On the basis of the evidence from our polyphasic study, a novel genus, Allosalinactinospora gen. nov., is proposed, with the type species Allosalinactinospora lopnorensis gen. nov., sp. nov. The type strain of Allosalinactinospora lopnorensis is strain CA15-2T ( = DSM 45697T = CGMCC 4.7074T).
