The 16S Rrna Gene

A Gram-reaction-positive, high DNA G+C content, non-motile actinobacterium, strain D7-21T, was isolated from dried bat dung inside a natural cave and its taxonomic status was examined by using a polyphasic approach. The 16S rRNA gene sequence study showed that the isolate belonged to the genus Rhodococcus and formed a cluster with Rhodococcus defluvii (98.98 % gene similarity), Rhodococcus equi (98.62 %) and Rhodococcus kunmingensis (97.66 %). Whole-cell hydrolysates contained meso-diaminopimelic acid, arabinose and galactose as the diagnostic diamino acid and sugars. MK-8(H2) was the predominant menaquinone. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, an unknown phosphoglycolipid and an unknown glycolipid. Mycolic acids were present. The major fatty acids were C16 : 0, C18 : 1ω9c and 10-methyl C18 : 0. The DNA G+C content was 70.1 mol%. A battery of phenotypic features and DNA–DNA relatedness data support that strain D7-21T ( = KCTC 29469T = DSM 46727T) represents a novel species of the genus Rhodococcus, for which Rhodococcus antrifimi sp. nov. is proposed.

Taxonomic Approach

An aerobic, Gram-stain-positive actinomycete, designated strain 3SM4-07T, was characterized using a polyphasic taxonomic approach. The strain produced branching mycelium which fragmented into short or elongated rods. The whole-cell hydrolysates contained ll-2,6-diaminopimelic acid as the diagnostic diamino acid, with glucose and ribose as the main sugars. The predominant cellular fatty acids were anteiso-C15  :  0, iso-C15  :  0 and iso-C16  :  0.The predominant menaquinone was MK-9(H4). Phospholipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylinositol and phosphatidylinositol mannoside. Mycolic acids were absent. The DNA G+C content was 72.3 mol%. Strain 3SM4-07T formed a phylogenetic line within the genus Jiangella and its 16S rRNA gene sequence was related most closely to Jiangella alkaliphila D8-87T (99.0 % similarity), Jiangella muralis 15-Je-017T (98.8 %), Jiangella alba YIM 61503T (98.6 %) and Jiangella gansuensis YIM 002T (98.6 %). However, mean DNA–DNA hybridization values revealed that strain 3SM4-07T differed from the closest species previously described in this genus. Data from phenotypic, chemotaxonomic and molecular analyses between strain 3SM4-07T and recognized species of the genus Jiangella indicate that strain 3SM4-07T is a representative of a novel species of the genus Jiangella, for which the name Jiangella mangrovi sp. nov. is proposed. The type strain is 3SM4-07T ( = BCC 60398T = NBRC 109648T).

An obligately aerobic, Gram-negative, non-spore-forming, non-motile, spherical bacterium, designated strain 04OKA010-24T, was isolated from seawater surrounding the hard coral Galaxea fascicularis L., collected at Majanohama, Akajima, Japan, and was subjected to a polyphasic taxonomic study. Phylogenetic analyses based on the 16S rRNA gene sequence indicated that the new strain represented a member of the phylum ‘Verrucomicrobia’ and shared 84–95 % sequence similarity with cultivated strains of ‘Verrucomicrobia’ subdivision 4. Amino acid analysis of the cell-wall hydrolysate indicated the absence of muramic acid and diaminopimelic acid, which suggested that the strain did not contain peptidoglycan in the cell wall. The G+C content of the DNA was 53.9 mol%. MK-7 was the major menaquinone and C14 : 0, C18 : 1 ω9c and C18 : 0 were the major fatty acids. On the basis of these data, it was concluded that strain 04OKA010-24T represents a novel species in a new genus in subdivision 4 of the phylum ‘Verrucomicrobia’, for which the name Coraliomargarita akajimensis gen. nov., sp. nov. is proposed. The type strain of Coraliomargarita akajimensis is 04OKA010-24T (=MBIC06463T=IAM 15411T=KCTC 12865T).

Three novel bacterial strains were isolated from a soil sample collected in Japan by culture on a GPM agar plate supplemented with superoxide dismutase and catalase. The strains were Gram-positive, catalase-positive, non-motile bacteria with l-ornithine as a diagnostic diamino acid of the peptidoglycan. The acyl type of the peptidoglycan was N-glycolyl. The major menaquinones were MK-12, 13 and 14. Mycolic acids were not detected. G+C contents of the DNA were in the range 69–71 mol%. Comparative 16S rRNA gene sequence analysis revealed that the isolates belonged to the genus Microbacterium and were closely related to Microbacterium terregens, Microbacterium aurum, Microbacterium koreense, Microbacterium schleiferi and Microbacterium lacticum. However, M. aurum, M. koreense and M. lacticum clearly differed from the isolated strains based on the presence of l-lysine as the cell-wall diamino acid and various other chemotaxonomic characteristics. Levels of DNA–DNA relatedness showed that the isolated strains represented three separate genomic species. Based on both phenotypic and genotypic data, the following novel species of the genus Microbacterium are proposed: Microbacterium deminutum sp. nov. (type strain KV-483T=NRRL B-24453T=NBRC 101278T), Microbacterium pumilum sp. nov. (type strain KV-488T=NRRL B-24452T=NBRC 101279T) and Microbacterium aoyamense sp. nov.

A novel actinomycete, strain ST1-08T, was isolated from the stem of Stemona sp. in Thailand. The taxonomic position of this isolate was determined by using a polyphasic approach. Strain ST1-08T contained meso-diaminopimelic acid in the cell-wall peptidoglycan, and arabinose and galactose as diagnostic sugars of the whole-cell hydrolysate, which are typical properties of members of the genus Amycolatopsis. Strain ST1-08T grew at 15–40 °C, pH 6–9 and on 5 % (w/v) NaCl. Gelatin liquefaction, starch hydrolysis and skimmed milk peptonization were positive. The strain utilized l-arabinose, d-glucose, glycerol, myo-inositol, d-mannitol and l-rhamnose. The predominant menaquinone was MK-9(H4) and the major cellular fatty acids were iso-C16 : 0 and iso-C15 : 0.The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, hydroxyl-phosphatidylethanolamine, phosphatidylinositol and phosphatidylglycerol. The 16S rRNA gene sequence analysis revealed that the strain was closely related to Amycolatopsis pretoriensis JCM 12673T (98.99 %) and Amycolatopsis lexingtonensis JCM 12672T (98.87 %). The DNA G+C content of strain ST1-08T was 71.2 mol%. The DNA–DNA relatedness values among strain ST1-08T, A. pretoriensis JCM 12673T and A. lexingtonensis JCM 12672T were lower than 70 %, the cut-off level for assigning strains to the same species. On the basis of phenotypic and genotypic characteristics, strain ST1-08T represents a novel species of the genus Amycolatopsis, for which the name Amycolatopsis stemonae is proposed. The type strain is ST1-08T( = JCM 30050T = PCU 339T = TISTR 2278T).

A polyphasic study was undertaken to establish the taxonomic status of a Gram-positive, aerobic actinomycete, strain HPA177T, isolated from a marine sponge, Hymeniacidon perleve. The organism formed branching, non-fragmenting vegetative hyphae and produced black pigment. Chemotaxonomic characteristics were consistent with its assignment to the genus Actinoalloteichus. Analysis of the 16S rRNA gene sequence showed that strain HPA177T formed a robust clade with type strains of the genus Actinoalloteichus, but was distinct from them. A number of phenotypic characteristics also readily distinguished strain HPA177T from species of the genus Actinoalloteichus with validly published names. On the basis of the above data, it is proposed that strain HPA177T represents a novel species, Actinoalloteichus hymeniacidonis sp. nov. The type strain of Actinoalloteichus hymeniacidonis is HPA177T (=CGMCC 4.2500T=JCM 13436T).
