Emended Description

A taxonomic study was carried out on strain DLFJ1-1T, which was isolated from an oil-degrading bacterial consortium, enriched by the surface seawater from around the Dalian Peninsula. The isolate was Gram-reaction-negative, oxidase- and catalase-positive, short-rod-shaped and non-motile. Growth was observed at salinities from 0.5 to 15 % and at temperatures from 4 to 37 °C; the strain was unable to degrade gelatin or to reduce nitrate. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain DLFJ1-1T belonged to the genus Thioclava , with the highest sequence similarity (96.4 %) to Thioclava pacifica TL 2T, while the similarities to other species examined were all below 95.0 %. The principal fatty acids were C19 : 0ω8c cyclo and summed feature 8 (C18 : 1ω7c/ω6c). The major quinone of strain DLFJ1-1T was Q10. The major polar lipids of strain DLFJ1-1T were phosphatidylethanolamine and phosphatidylglycerol. The G+C content of the chromosomal DNA was 62.5 mol%. The combined genotypic and phenotypic data show that strain DLFJ1-1T represents a novel species of the genus Thioclava , for which the name Thioclava dalianensis sp. nov. is proposed, with the type strain DLFJ1-1T ( = CGMCC 1.12325T = LMG 27290T = MCCC 1A03957T). An emended description of the genus Thioclava is also proposed.

Taxonomic Approach

A Gram-staining-negative, rod-shaped, non-spore-forming bacterium, designated strain RG4-7T, was isolated from the moss Polytrichastrum formosum collected from Gawalong glacier in Tibet, China, and characterized by using a polyphasic taxonomic approach. The predominant fatty acids of strain RG4-7T were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), iso-C15 : 0 and iso-C17 : 0 3-OH. The major polar lipids were phosphatidylethanolamine, one unidentified aminophospholipid, one unidentified phospholipid, two unidentified aminolipids and one unidentified lipid. Strain RG4-7T contained MK-7 as the dominant menaquinone and the G+C content of its genomic DNA was 39.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain RG4-7T was affiliated to species of the genus Mucilaginibacter , and its closest relative was Mucilaginibacter jinjuensis YC7004T (97.0 % sequence similarity). However, the DNA–DNA relatedness between this strain and strain RG4-7T was only 49.1±3.7 %. Based on phylogenetic inference and phenotypic data, strain RG4-7T is considered to represent a novel species of the genus Mucilaginibacter , for which the name Mucilaginibacter polytrichastri sp. nov. is proposed. The type strain is RG4-7T ( = CGMCC 1.12493T = DSM 26907T). An emended description of the genus Mucilaginibacter is also proposed.

Strain WPAGA1T was isolated from marine sediment of the west Pacific Ocean. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate belonged to the genus Flammeovirga . Strain WPAGA1T exhibited highest 16S rRNA gene sequence similarity with Flammeovirga yaeyamensis NBRC 100898T (98.1 %) and lower sequence similarity with Flammeovirga arenaria IFO 15982T (94.6 %) and other members of the genus Flammeovirga (<94.2 %). DNA–DNA relatedness studies showed that strain WPAGA1T was distinct from F. yaeyamensis NBRC 100898T and F. arenaria NBRC 15982T (43±4 % and 32±2 % relatedness values, respectively). Strain WPAGA1T could be distinguished from all known members of the genus Flammeovirga by a number of phenotypic features. However, the dominant fatty acids of strain WPAGA1T (iso-C15 : 0, C16 : 0 and C20 : 4ω6,9,12,15c), the major polyamine (cadaverine) and the G+C content of the chromosomal DNA (32.9 mol%) were consistent with those of members of the genus Flammeovirga . Based on phenotypic and chemotaxonomic features and 16S rRNA gene sequences, strain WPAGA1T can be assigned to the genus Flammeovirga as a representative of a novel species, for which the name Flammeovirga pacifica sp. nov. is proposed; the type strain is WPAGA1T ( = CCTCC AB 2010364T = LMG 26175T = DSM 24597T = MCCC 1A06425T).

In Captivity

A novel bacterial strain, designated M8T, was isolated from milk of a female macaque bred in captivity. The strain was Gram-stain-positive, anaerobic, irregular coccoid–rod-shaped without catalase activity. Analysis of 16S rRNA gene sequence similarity revealed that the isolate was most closely related to Alloscardovia omnicolens CCUG 31649T (96.4 %) and Metascardovia criceti OMB105T (96.6 %). Sequences of hsp60, fusA, and xfp genes also confirmed that the strain was most closely related to the type strains of A. omnicolens and M. criceti . The isolate produced fructose-6-phosphate phosphoketolase which is in agreement with classification within the family Bifidobacteriaceae . The major fatty acids were C18 : 1ω9c (35.8 %), C16 : 1 (6.2 %) and C14 : 0 (5.7 %). Polar lipid analysis revealed five different glycolipids, two unidentified phospholipids and diphosphatidylglycerol. The peptidoglycan was of the type A4α l-Lys–d-Asp with the presence of d(l)-alanine, d-glutamine, d-asparagine and l-lysine. The DNA G+C content of strain M8T was 50.1 mol%. On the basis of genetic, phylogenetic and phenotypic data, strain M8T represents a novel species of the genus Alloscardovia for which the name Alloscardovia macacae sp. nov. is proposed. The type strain is M8T ( = DSM 24762T = CCM 7944T). In addition, our results also revealed that Alloscardovia omnicolens DSM 21503T and Metascardovia criceti DSM 17774T do not belong to different genera within the family Bifidobacteriaceae . We therefore propose to reclassify Metascardovia criceti as Alloscardovia criceti comb. nov. An emended description of the genus Alloscardovia is also provided.

A Gram-staining-negative, rod-shaped and non-motile bacterial strain, designated 12C25T, was isolated from the crude-oil-degrading bacterial consortium enriched from mangrove sediment collected in Fujian Province, China. Optimal growth was observed at 25–28 °C, at pH 7.0 and in the presence of 2 % (w/v) NaCl + 2 % (w/v) KCl. Comparative 16S rRNA gene sequence analysis demonstrated that strain 12C25T shared the highest sequence similarity with members of the genus Muricauda (97.7–93.9 %), exhibiting 97.7 % sequence similarity and 33.7±4 % DNA–DNA relatedness to Muricauda aquimarina SW-63T. The DNA G+C content of strain 12C25T was 39.9 mol%. The dominant fatty acids were iso-C15 : 1 G, iso-C17 : 0 3-OH, iso-C15 : 0, C18 : 0 and iso-C15 : 0 3-OH, and menaquinone with six isoprene units (MK-6) was the only respiratory quinone. On the basis of phenotypic data and phylogenetic inference, the novel strain belongs to the genus Muricauda , but can readily be distinguished from known species of this genus and thus represents a novel species of the genus Muricauda. The name Muricauda zhangzhouensis sp. nov. is proposed and the type strain is 12C25T ( = CGMCC 1.11028T = MCCC 1F01096T = DSM 25030T).
