Pigmented Bacteria

Two aerobic, Gram-negative, non-motile, non-sporulating, yellow-pigmented bacteria, strains TH92T and TH91, were isolated from a hot spring located in Laibin, Guangxi, in the south-eastern geothermal area of China. The isolates grew at 40–77 °C (optimally at 70 °C) and at pH 6.0–9.5 (optimally at pH 7.5–8.0). Phylogenetic analysis of 16S rRNA gene sequences and levels of DNA–DNA relatedness together indicated that the new isolates represented a novel species of the genus Thermus with closest affinity to Thermus aquaticus, Thermus igniterrae and Thermus thermophilus. Compared with their closest relatives, strains TH92T and TH91 were able to assimilate a wider range of carbohydrates, amino acids and organic acids as sole carbon sources for growth, such as lactose and melibiose. The new isolates had lower combined levels of C16 : 0 and iso-C16 : 0 compared with their closest relatives. On the basis of polyphasic taxonomic characterization, strains TH92T and TH91 are considered to represent a single novel species of the genus Thermus, for which the name Thermus arciformis sp. nov. is proposed. The type strain is TH92T (=CGMCC 1.6992T =JCM 15153T).

Two non-motile, orange- or yellow-pigmented bacteria, designated strains KYW48T and KYW147T, were isolated from seawater collected from the South Sea, Republic of Korea. Cells of both strains were Gram-reaction-negative, aerobic and catalase- and oxidase-positive. The major fatty acids of strain KYW48T were C18 : 1ω7c (35.3 %), summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c) (22.7 %), C17 : 1ω6c (19.8 %), C14 : 0 2-OH (7.4 %) and C16 : 0 (5.9 %), and those of strain KYW147T were C18 : 1ω7c (36.0 %), summed feature 3 (18.3 %), C16 : 0 (14.7 %), 11-methyl C18 : 1ω7c (10.7 %), C16 : 0 2-OH (9.1 %) and C18 : 1ω9c (8.0 %). The predominant isoprenoid quinone of both strains was ubiquinone 10 (Q-10). The DNA G+C contents of strains KYW48T and KYW147T were 63.8 and 67.2 mol%, respectively. A phylogenetic tree based on 16S rRNA gene sequences showed that strains KYW48T and KYW147T were grouped with the members of the family Erythrobacteraceae and formed a distinct clade with the members of the genus Altererythrobacter (<95.7 % sequence similarity). On the basis of the evidence presented in this study, the novel species Altererythrobacter namhicola sp. nov. (type strain KYW48T  = KCTC 22736T  = JCM 16345T) and Altererythrobacter aestuarii sp. nov. (type strain KYW147T  = KCTC 22735T  = JCM 16339T) are proposed.

Methylobacterium Oryzae

Three pink-pigmented, facultatively methylotrophic strains, designated MP1, MP2 and MRT, were isolated from seawater from southern China and characterized. Analysis of their complete 16S rRNA gene sequences revealed that they constituted three separate phylogenetic groups, showing the highest levels of similarity with respect to some members of the genus Methylobacterium. PCR amplification also showed the gene coding for the α-subunit of methanol dehydrogenase (mxaF) to be present in all strains, indicating a methylotrophic metabolism. All three strains utilized d-fructose, ethanol and nutrient agar as carbon sources, but did not utilize sucrose, citrate, acetate or formaldehyde. On the basis of the phenotypic, phylogenetic and genotypic analyses, strain MRT represents a novel species, for which the name Methylobacterium salsuginis sp. nov. is proposed, with MRT (=CGMCC 1.6474T =NCCB 100140T) as the type strain. Strains MP1 and MP2 respectively represent novel strains of the species Methylobacterium oryzae and Methylobacterium lusitanum.

A novel strain, C-138T, belonging to the genus Corynebacterium was isolated from a severe thigh liposarcoma infection and its differentiation from Corynebacterium xerosis and Corynebacterium freneyi is described. Analysis of 16S rRNA gene sequences, rpoB sequences and the PCR profile of the 16S–23S spacer regions was not conclusive enough to differentiate strain C-138T from C. xerosis and C. freneyi. However, according to DNA–DNA hybridization data, strain C-138T constitutes a member of a distinct novel species. It can be differentiated from strains of C. xerosis and C. freneyi by colony morphology, the absence of α-glucosidase and some biochemical characteristics such as glucose fermentation at 42 °C and carbon assimilation substrates. The name Corynebacterium hansenii sp. nov. is proposed for this novel species; the type strain is C-138T (=CIP 108444T=CCUG 53252T).

Mycobacterium Simiae

Four strains isolated in the last 15 years were revealed to be identical in their 16S rRNA gene sequences to MCRO19, the sequence of which was deposited in GenBank in 1995. In a polyphasic analysis including phenotypic and genotypic features, the five strains (including MCRO19), which had been isolated in four European countries, turned out to represent a unique taxonomic entity. They are scotochromogenic slow growers and are genetically related to the group that included Mycobacterium simiae and 15 other species. The novel species Mycobacterium europaeum sp. nov. is proposed to accommodate these five strains. Strain FI-95228T ( = DSM 45397T  = CCUG 58464T) was chosen as the type strain. In addition, a thorough revision of the phenotypic and genotypic characters of the species related to M. simiae was conducted which leads us to suggest the denomination of the ‘Mycobacterium simiae complex’ for this group.

A novel actinobacterium, designated strain C4-31T, was isolated from soil collected from a cave. Cells were aerobic, Gram-reaction-positive, oxidase-negative, catalase-positive and non-motile cocci. Comparison of 16S rRNA gene sequences showed that the organism occupied a distinct phylogenetic position within the suborder Frankineae, with sequence similarity values of less than 93.2 % to members of this suborder. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The major menaquinone was MK-9(H4). The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside, an unknown aminophospholipid and an unknown phospholipid. The major fatty acids were iso-C16 : 0, C17 : 1ω6c and C16 : 0. The G+C content of the DNA was 62.8 mol%. On the basis of morphological and chemotaxonomic data as well as phylogenetic evidence, strain C4-31T ( = KCTC 39556T = DSM 100065T) is considered to represent the type strain of a novel species of a new genus in the suborder Frankineae, for which the name Antricoccus suffuscus gen. nov., sp. nov. is proposed.

A Gram-staining-negative, non-gliding, orange-pigmented bacterial strain, designated HMF2925T, was isolated from fresh water in Korea. The phylogenetic tree based on 16S rRNA gene sequences showed that strain HMF2925T formed a distinct lineage within the genus Emticicia. Strain HMF2925T was closely related to Emticicia oligotrophica DSM 17448T (95.5 %) and Emticicia ginsengisoli Gsoil 085T (94.1 %). The major fatty acids of strain HMF2925T were summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c), iso-C15 : 0, C16 : 1ω5c and C16 : 0.The major polar lipids of strain HMF2925T were phosphatidylethanolamine, phosphatidylinositol, diphosphatidylglycerol, phosphatidylglycerol, an unidentified glycolipid, two unidentified amino lipids and three unidentified polar lipids. The DNA G+C content of strain HMF2925T was 36.5 mol%. On the basis of the evidence presented in this study, strain HMF2925T represents a novel species of the genus Emticicia, for which the name Emticicia aquatica sp. nov. is proposed. The type strain is HMF2925T ( = KCTC 42574T = CECT 8858T).

A Gram-stain-positive, aerobic, non-motile, psychrophilic bacterium, designated strain Cr6-08T, was isolated from alpine glacier cryoconite. Growth of strain Cr6-08T occurred at 1–25 °C. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain Cr6-08T is most closely related to members of the genus Arthrobacter. Strain Cr6-08T possessed chemotaxonomic properties consistent with those of the genus Arthrobacter, such as peptidoglycan type A3α (l-Lys–l-Ala4), MK-9(H2) as major menaquinone and anteiso- and iso-branched compounds (anteiso-C15 : 0 and iso-C15 : 0) as major cellular fatty acids. The polar lipid profile contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, one unknown glycolipid and three unknown polar lipids. The genomic DNA G+C content of strain Cr6-08T was 57.3 mol%. On the basis of phenotypic and chemotaxonomic characteristics, phylogenetic analysis and DNA–DNA relatedness data, strain Cr6-08T is considered to represent a novel species of the genus Arthrobacter, for which the name Arthrobacter cryoconiti sp. nov. is proposed.

The Yamal Peninsula

A facultatively anaerobic nitrogen-fixing bacterium, strain C7T, was isolated from a permafrost cryopeg on the Yamal Peninsula, Russia. Comparative analysis of 16S rRNA gene sequences revealed that this bacterium was closely related to Celerinatantimonas diazotrophica S-G2-2T with a similarity of 95.5 %. Strain C7T differed from Celerinatantimonas diazotrophica in its ability to hydrolyse gelatin and inability to use d-mannose, melibiose, l-rhamnose, myo-inositol, lactose, lactulose, d-mannitol, trehalose, dl-lactate, glycogen or l-proline as sole carbon sources. In addition, strain C7T grew over a temperature range of 0–34 °C with optimum growth at 18–22 °C. The whole-cell fatty acid profile included C16 : 0, C16 : 1ω7, C18 : 1ω7, C17 cyclo and summed feature 2 [comprising C12 : 0 aldehyde and/or unknown fatty acid 10.913 (MIDI designation) and/or iso-C16 : 1/C14 : 0 3-OH]. The DNA G+C content was 44.7 mol%. Strain C7T is thus considered to represent a novel species, for which the name Celerinatantimonas yamalensis sp. nov. is proposed. The type strain is C7T ( = VKM B-2511T = DSM 21888T).

A novel Gram-positive, non-motile, rod-shaped bacterium, designated strain RB-62T, was isolated during a study of culturable bacteria from the gut of Moechotypa diphysis (Pascoe) and its taxonomic position was investigated. Strain RB-62T grew at 15–30 °C and pH 5.0–8.5. The isoprenoid quinones were menaquinones MK-11 (77.1 %), MK-10 (11.7 %) and MK-12 (11.2 %). The major cellular fatty acids were anteiso-C15 : 0 (34.6 %), anteiso-C17 : 0 (29.8 %), iso-C16 : 0 (17.0 %) and cyclohexyl-C17 : 0 (11.4 %). The diagnostic diamino acid of the cell-wall peptidoglycan was 2,4-diaminobutyric acid. The G+C content of the genomic DNA of strain RB-62T was 70.3 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain RB-62T was affiliated with the genus Herbiconiux cluster within the family Microbacteriaceae, and was related most closely to Herbiconiux ginsengi wged11T (98.08 % similarity). The level of DNA–DNA relatedness between strain RB-62T and H. ginsengi wged11T was 43.2 % (reciprocal 66.7 %). Phenotypic and phylogenetic characteristics clearly distinguished strain RB-62T from recognized species of the genus Herbiconiux. Based on data from the present polyphasic study, strain RB-62T is considered to represent a novel species of the genus Herbiconiux, for which the name Herbiconiux moechotypicola sp. nov. is proposed. The type strain is RB-62T ( = KCTC 19653T = JCM 16117T).

A Gram-negative, motile, rod-shaped bacterium (WSF2T) was isolated from coastal seawater of the Boso Peninsula in Japan. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain WSF2T represented a separate lineage within the genus Pseudovibrio. The DNA G+C content of strain WSF2T was 51.7 mol%. DNA–DNA hybridization values between strain WSF2T and the type strains of Pseudovibrio species were significantly lower than those accepted as the phylogenetic definition of a species. Furthermore, some biochemical characteristics indicated that strain WSF2T differed from other Pseudovibrio species. Based on these characteristics, it is proposed that the isolate represents a novel species, Pseudovibrio japonicus sp. nov. The type strain is WSF2T (=IAM 15442T=NCIMB 14279T=KCTC 12861T).
