Psychrotolerant Bacterium

Strain H38T was isolated during a study on the diversity of culturable psychrotolerant bacteria in raw milk. Comparative 16S rRNA gene sequence analysis showed that strain H38T belongs to the genus Chryseobacterium (family Flavobacteriaceae, phylum Bacteroidetes), with the highest similarity (96.7 %) to Chryseobacterium hispanicum VP48T. Strain H38T grows aerobically, at 4–41 °C, with 0–2.5 % NaCl and at pH 6.5–10.5. Light induces the formation of yellow carotenoid pigments. The dominant cellular fatty acids are 15 : 0 iso (41.6 %), 15 : 0 anteiso (16.6 %) and 17 : 0 iso 3-OH (10.3 %). The G+C content of the DNA is 37.8 mol%. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain H38T (=LMG 24029T =DSM 19056T) is classified in the genus Chryseobacterium as the type strain of a novel species, for which the name Chryseobacterium haifense sp. nov. is proposed.

Actinomycete Strain

A novel actinomycete, strain N3-7T, was isolated from a natural cave in Jeju, Republic of Korea, using a dilution method and was subjected to characterization using polyphasic taxonomy. A 16S rRNA gene sequence analysis revealed that the organism belonged to the phylogenetic cluster of the genus Actinocorallia and was most closely related to Actinocorallia glomerata and Actinocorallia longicatena (97.6 and 97.5 % similarity, respectively). The main chemotaxonomic properties of strain N3-7T, such as the principal amino acid of the peptidoglycan, the predominant menaquinone and the polar lipid profile, supported classification in the genus Actinocorallia. The organism was readily differentiated from Actinocorallia species with validly published names on the basis of a broad range of phenotypic properties. Thus the isolate represents a novel species of the genus Actinocorallia, for which the name Actinocorallia cavernae sp. nov. is proposed. The type strain is strain N3-7T (=JCM 13278T=NRRL B-24429T).

Gene Sequence Analysis

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).

An equol-producing bacterium, strain DZET, which was isolated from human faeces, was characterized by morphological, biochemical and molecular methods. The isolate was Gram-positive, obligately anaerobic, non-spore-forming, asaccharolytic and rod-shaped. 16S rRNA gene sequence analysis showed 92.8, 91.0, 91.1 and 90.6 % similarities with Slackia faecicanis, Slackia exigua, Slackia heliotrinireducens and Slackia isoflavoniconvertens, respectively. Based on these data, we propose a novel species of the genus Slackia, Slackia equolifaciens sp. nov. The major cellular fatty acids are C14 : 0, C18 : 1 ω9c and C18 : 1 ω9c DMA (dimethyl acetal). The DNA G+C content of the strain is 60.8 mol%. The type strain of S. equolifaciens sp. nov. is DZET (=JCM 16059T =CCUG 58231T).

A Gram-negative, strictly aerobic, rod-shaped, non-motile, non-spore-forming bacterial strain, designated TR6-04T, was isolated from compost and characterized taxonomically by using a polyphasic approach. The organism grew optimally at 30 °C and at pH 6.5–7.0. The isolate was positive for catalase and oxidase tests but negative for gelatinase, indole and H2S production. Comparative 16S rRNA gene sequence analysis showed that strain TR6-04T fell within the radiation of the cluster comprising Sphingobacterium species and clustered with Sphingobacterium mizutaii ATCC 33299T (96.7 % sequence similarity); the similarity to sequences of other species within the family Sphingobacteriaceae was less than 92.0 %. The G+C content of the genomic DNA was 38.7 mol%. The predominant respiratory quinone was MK-7. The major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 4 (iso-C15 : 0 2-OH and/or C16 : 1 ω7c). These chemotaxonomic data supported the affiliation of strain TR6-04T to the genus Sphingobacterium. However, on the basis of its phenotypic properties and phylogenetic distinctiveness, strain TR6-04T (=KCTC 12579T=LMG 23402T=CCUG 52468T) should be classified as the type strain of a novel species, for which the name Sphingobacterium daejeonense sp. nov. is proposed.

A novel actinobacterium, strain P30T, was isolated from jeotgal, a traditional Korean fermented seafood. Cells were aerobic, Gram-positive, non-motile and coccoid. Optimal growth occurred at 30–37 °C, at pH 8–9 and in the presence of 0–2 % (w/v) NaCl. Based on 16S rRNA gene sequence analysis, strain P30T was phylogenetically closely related to Kocuria carniphila, Kocuria gwangalliensis, Kocuria rhizophila, Kocuria marina, Kocuria rosea and K. varians with levels of similarity of 98.6, 98.2, 98.1, 97.4, 97.3 and 97.3 %, respectively, to the type strains of these species. Levels of DNA–DNA relatedness between strain P30T and the type strains of K. carniphila, K. rhizophila, K. marina, K. rosea and K. varians were 37, 43, 37, 25 and 17 %, respectively. The predominant menaquinone of strain P30T was MK-7. Major cellular fatty acids were anteiso-C15 : 0, iso-C15 : 0 and iso-C16 : 0. The genomic DNA G+C content of strain P30T was 70.2 mol%. Based on these data, strain P30T is considered to represent a novel species of the genus Kocuria, for which the name Kocuria atrinae sp. nov. is proposed. The type strain is P30T (=KCTC 19594T=JCM 15914T).

The Antarctic

A yellow-pigmented, Gram-negative and aerobic bacterial strain, designated AT1026T, was isolated from a terrestrial sample from the Antarctic. Results of 16S rRNA gene sequence analysis indicated that the Antarctic isolate belonged to the genus Flavobacterium, with the highest sequence similarity to Flavobacterium tegetincola (96·4 %). Cells were non-motile, non-gliding and psychrotolerant, with optimum and maximum temperatures of about 20 and 25 °C. Flexirubins were absent. The major isoprenoid quinone (MK-6), predominant cellular fatty acids (iso-C15 : 1 G, iso-C15 : 0 and a mixture of C16 : 1 ω7c and/or iso-C15 : 0 2-OH) and DNA G+C content (38 mol%) of the Antarctic isolate were consistent with those of the genus Flavobacterium. In contrast, several phenotypic characters can be used to differentiate this isolate from other flavobacteria. The polyphasic data presented in this study indicated that this isolate should be classified as a novel species in the genus Flavobacterium. The name Flavobacterium antarcticum sp. nov. is therefore proposed for the Antarctic isolate; the type strain is AT1026T (=IMSNU 14042T=KCTC 12222T=JCM 12383T).

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).
