Diamino Acid

A Gram-positive, aerobic, non-motile actinobacterium, designated strain 6014T, was isolated from a soil sample collected from Qinghai province, north-west China, and subjected to a polyphasic taxonomic study. The isolate formed elementary branching hyphae and abundant aerial mycelia with globose sporangia on ISP 4 and R2A media. Whole-cell hydrolysates of strain 6014T contained arabinose, galactose and ribose as diagnostic sugars and meso-diaminopimelic acid as the diagnostic diamino acid. The polar lipids consisted of phosphatidylmethylethanolamine, phosphatidylethanolamine, hydroxy-phosphatidylethanolamine, N-acetylglucosamine-containing phospholipids, two unknown phospholipids and an unknown glycolipid. The menaquinone system contained MK-9(H2) and MK-9(H4). The major fatty acids were C14 : 0, i-C15 : 0, C16 : 0 and 10-methyl-C16 : 1. The genomic DNA G+C content of the isolate was 69.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 6014T fell within the radius of the suborder Streptosporangineae, in which the strain formed a distinct lineage next to genera of the family Streptosporangiaceae. Based on data from this polyphasic study, strain 6014T can be readily distinguished from previously described organisms and represents a member of a novel species within a new genus in the suborder Streptosporangineae. The name Sinosporangium album gen. nov., sp. nov. is proposed with 6014T (=DSM 45181T =KCTC 19655T) as the type strain.

A novel halophilic actinobacterium, designated strain TRM 49201T, was isolated from a hypersaline soil in Xinjiang Province, north-west China. The strain was aerobic, Gram-stain-positive and halophilic. The aerial mycelium was chaotic with irregular branches, and spherical sporangia containing several spherical spores developed at mycelial aggregations. The strain had an optimum NaCl concentration for growth of 8–13 % (w/v). The whole-cell sugar pattern of strain TRM 49201T consisted of xylose and ribose. The predominant menaquinones were MK-9(H4), MK-9(H6) and MK-10(H2). The polar lipids were diphosphatidylglycerol, phosphatidylinositol mannoside, phosphatidylinositol, phosphatidylglycerol, phosphatidylcholine and four unknown phospholipids. The major fatty acids were anteiso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0. The G+C content of the genomic DNA was 70 mol%. Phylogenetic analysis showed that strain TRM 49201T can be distinguished from representatives of Glycomyces, Stackebrandtia and Haloglycomyces, the three existing genera in the family Glycomycetaceae, based on low 16S rRNA gene sequence similarities ( < 94.42 %). Strain TRM 49201T is thus considered to represent a novel species of a new genus in the family Glycomycetaceae, for which the name Paraglycomyces xinjiangensis gen. nov., sp. nov. is proposed. The type strain of Paraglycomyces xinjiangensis is TRM 49201T ( = NRRL B-24926T = CCTCC AA 2013002T = KACC 17683T).

Water Cooling System

A motile, rod-shaped, yellow-pigmented bacterium, designated strain CW1T, was isolated from a water-cooling system in the Republic of Korea. Cells were Gram-stain-positive, aerobic, catalase-positive and oxidase-negative. Strain CW1T formed slender rods with unusual bulbous protuberances. The major fatty acids were iso-C16 : 1 (33.7 %), anteiso-C15 : 0 (27.2 %), iso-C14 : 0 (13.3 %) and C16 : 0 (10.8 %). The cell-wall peptidoglycan was of type B2β, containing lysine as the diamino acid. The respiratory quinones were menaquinones with 12, 13 and 14 isoprene units. A phylogenetic tree based on 16S rRNA gene sequences showed that strain CW1T formed an evolutionary lineage within the radiation enclosing members of the family Microbacteriaceae and was related to, but distant from, members of the genera Microcella and Yonghaparkia. On the basis of the evidence presented, strain CW1T is considered to represent a novel species of a new genus in the family Microbacteriaceae, for which the name Chryseoglobus frigidaquae gen. nov., sp. nov. is proposed. The type strain of Chryseoglobus frigidaquae is CW1T (=KCTC 13142T =JCM 14730T).

Actinomycete Strain

A novel actinomycete strain, designated TRM F103T, was isolated from a hypersaline habitat of the Tarim basin in Xinjiang province, north-west China. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate belonged to the genus Amycolatopsis and was most closely related to Amycolatopsis halophila YIM 93223T (99.3 % 16S rRNA gene sequence similarity). However, DNA–DNA relatedness between these two strains, based on triplicate experiments, was only 31.6 %. The isolate contained meso-diaminopimelic acid and ribose, glucose and galactose as the major whole-cell sugars. The predominant menaquinone was MK-8(H4). The major fatty acids were iso-C16 : 0 and C16 : 0. The polar lipids were diphosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine and glucosamine-containing phospholipids. The G+C content of the genomic DNA was 66.4 mol%. The phenotypic data clearly distinguished the isolate from its closest relatives. The combined phylogenetic, chemotaxonomic and phenotypic data indicate that the isolate represents a novel species of the genus Amycolatopsis. The proposed name is Amycolatopsis salitolerans sp. nov., with TRM F103T ( = JCM 15899T = CCTCC AB 208326T) as the type strain.

Isoprenoid Quinones

An aerobic, non-motile actinobacterium, strain QAIII60T, was isolated from virgin forest soil of Kanas Nature Reserve, Xinjiang, north-west China. The isolate produced a very scant aerial mycelium that fragmented into cylindrical spores and a non-fragmented substrate mycelium with occasional septa. Whole-cell hydrolysates contained meso-diaminopimelic acid, arabinose, galactose, glucose, ribose and rhamnose (trace). The diagnostic polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, hydroxyphosphatidylethanolamine and ninhydrin-positive phosphoglycolipids. The major cellular fatty acids were iso-C16 : 0, iso-C14 : 0, iso-C16 : 1 H and C17 : 1ω6c. The isoprenoid quinones consisted of MK-9(H4) and MK-10(H2). The G+C content of the genomic DNA was 72.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain QAIII60T formed a distinct phyletic line that was most closely, albeit loosely, associated with the genus Actinophytocola. A number of physiological characteristics differentiated the isolate from members of the genus Actinophytocola. On the basis of these data, we propose that strain QAIII60T ( = CGMCC 4.4663T  = NBRC 106673T) be assigned as the type strain of a novel species, Actinophytocola xinjiangensis sp. nov.
