Taxonomic Studies

Taxonomic studies were performed on a novel carotenoid-producing strain, designated AJ003T, isolated from faeces of Antarctic penguins. Cells of strain AJ003T were aerobic, Gram-stain-positive, cocci-shaped and orange. Strain AJ003T was capable of growing in a broad temperature range, including sub-zero growth (below − 20 to 30 °C). 16S rRNA gene sequence analysis revealed that strain AJ003T was closely related to Planococcus halocryophilus Or1T (97.4 % similarity), Planococcus antarcticus DSM 14505T (97.3 %), Planococcus kocurii NCIMB 629T (97.3 %), and Planococcus donghaensis JH1T (97.1 %). The predominant cellular fatty acids were anteiso-C15 : 0, and iso-C16 : 0.MK-7 and MK-8 were the quinones identified, and the major pigment was glycosyl-4,4′-diaponeurosporen-4′-ol-4-oic acid. The major polar lipid was phosphatidylglycerol. DNA–DNA relatedness of strain AJ003T with respect to its closest phylogenetic neighbours was 38.2 ± 0.5 % for Planococcus halocryophilus DSM 24743T, 32.2 ± 0.2 % for Planococcus antarcticus DSM 14505T, 21.0 ± 0.3 % for Planococcus kocurii DSM 20747T and 18.6 ± 1.4 % for Planococcus donghaensis KCTC 13050T. The DNA G+C content of strain AJ003T was 40.0 ± 0.6 mol%. Based on the phenotypic, chemotaxonomic and phylogenetic data, strain AJ003T is concluded to represent a novel species of the genus Planococcus, for which the name Planococcus faecalis sp. nov. is proposed. The type strain is AJ003T ( = KCTC 33580T = CECT 8759T).

A Gram-stain-positive, oxidase- and catalase-positive, non-motile, non-spore-forming, halotolerant, coccoid bacterium, designated strain NY-2T, was isolated from a seaside soil sample from Shandong Province, China. Strain NY-2T was able to grow in the presence of 0–23 % (w/v) NaCl and at pH 4.5–10.0 and 5–42 °C; optimum growth was observed with 3–8 % (w/v) total salts and at pH 6.5–8.0 and 28–37 °C. Chemotaxonomic analyses, including fatty acid profiles, menaquinones and polar lipids, supported the affiliation of strain NY-2T to the genus Jeotgalicoccus. The predominant menaquinone of strain NY-2T was menaquinone 7 (MK-7) (100 %) and the major cellular fatty acids were iso-C15 : 0 (49.0 %) and anteiso-C15 : 0 (19.6 %). Cellular polar lipids were phosphatidylglycerol, diphosphatidylglycerol and several unidentified phospholipids. The DNA G+C content of strain NY-2T was 36.8 mol%. Based on 16S rRNA gene sequence analysis, strain NY-2T formed a coherent cluster with Jeotgalicoccus marinus JSM 076033T, Jeotgalicoccus halotolerans YKJ-101T and Jeotgalicoccus psychrophilus YKJ-115T. Phylogenetic analysis, DNA–DNA relatedness data, phenotypic characteristics and chemotaxonomic data indicated that strain NY-2T (=CCTCC AB 208288T =JCM 15687T) should be classified as the type strain of a novel species of the genus Jeotgalicoccus, for which the name Jeotgalicoccus huakuii sp. nov. is proposed.

Two novel Gram-negative, oxidase- and catalase-positive, rod-shaped bacterial strains, designated YCSA28T and YCSA39, were isolated from sediment of Daqiao saltern, Jimo, Qingdao, on the east coast of China. The two strains grew optimally at 28–30 °C, at pH 7.5 and in the presence of 7–8 % (w/v) NaCl. They were assigned to the genus Halomonas, class Gammaproteobacteria, based on 16S rRNA gene sequence analysis. The major cellular fatty acids of the two strains were C18 : 1ω7c (42.9 %), C16 : 0 (23.1 %) and C16 : 1ω7c/ω6c (18.0 %), and Q-9 was the major ubiquinone. The G+C content of the DNA of strains YCSA28T and YCSA39 was 63.7 and 63.9 mol%, respectively. The predominant respiratory lipoquinone, cellular fatty acid profiles and DNA G+C content of strains YCSA28T and YCSA39 were consistent with those of recognized species of the genus Halomonas. Levels of DNA–DNA relatedness between strains YCSA28T and YCSA39, between YCSA28T and Halomonas ventosae Al12T, and between YCSA39 and H. ventosae Al12T were 95, 45 and 50 %, respectively. Together, these data indicated that strains YCSA28T and YCSA39 represent a single novel species of the genus Halomonas, for which the name Halomonas daqiaonensis sp. nov. is proposed. The type strain is YCSA28T ( = CGMCC 1.9150T  = NCCB 100305T  = MCCC 1B00920T).

Gene Sequence Analysis

A Gram-positive, aerobic to microaerophilic, non-motile bacterial strain, designated MJ21T, was isolated from farm soil and was characterized to determine its taxonomic position by using a polyphasic approach. On the basis of 16S rRNA gene sequence analysis, strain MJ21T was placed within the genus Agromyces, and exhibited relatively high levels of similarity to Agromyces ulmi XIL01T (97.8 %), Agromyces aurantiacus YIM 21741T (97.1 %), Agromyces mediolanus JCM 3346T (96.7 %), A. mediolanus JCM 1376 (99.1 %), A. mediolanus JCM 9632 (99.1 %), A. mediolanus JCM 9633 (98.9 %) and A. mediolanus JCM 9631 (96.5 %). Chemotaxonomic data also supported the classification of strain MJ21T within the genus Agromyces. The new isolate contained MK-12 as the predominant menaquinone and rhamnose, galactose and xylose as cell-wall sugars. The major cellular fatty acids (>10 % of the total) were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. Cell-wall amino acids were 2,4-diaminobutyric acid, glutamic acid, glycine and alanine. Diphosphatidylglycerol, phosphatidylglycerol, two unknown glycolipids and one unidentified phospholipid were detected as polar lipids. The DNA G+C content of strain MJ21T was 73.4 mol%. However, levels of DNA–DNA relatedness between strain MJ21T and the seven phylogenetically closest Agromyces strains ranged from 14 to 56 %, showing clearly that the new isolate represents a novel genomic species. Strain MJ21T could be differentiated clearly from its phylogenetic neighbours on the basis of phenotypic, genotypic and chemotaxonomic features. Therefore, strain MJ21T is considered to represent a novel species of the genus Agromyces, for which the name Agromyces soli sp. nov. is proposed. The type strain is MJ21T ( = KCTC 19549T  = JCM 16247T).

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).
