Relatedness Data

Two novel Microbacterium species are described on the basis of phenotypic, chemotaxonomic and genotypic studies. The two strains, designated YM10-847T and YM11-607T, were isolated from river sediment and unidentified hydroid, respectively, of a marine lake. The strains were Gram-positive, catalase-positive bacteria with l-ornithine as the diagnostic diamino acid of the peptidoglycan. The acyl type of the peptidoglycan was N-glycolyl. The major menaquinones were MK-10 and MK-11 for YM10-847T, and MK-11 and MK-12 for YM11-607T. Mycolic acids were not detected. The DNA G+C content of strains YM10-847T and YM11-607T was 67.8 and 71.6 mol%, respectively. Comparative 16S rRNA gene sequence analysis revealed that the two strains belong to the genus Microbacterium. DNA–DNA relatedness data showed that YM10-847T and YM11-607T are two novel species of this genus. On the basis of these results, strains YM10-847T and YM11-607T represent two novel species of the genus Microbacterium, for which the names Microbacterium sediminicola sp. nov. and Microbacterium marinilacus sp. nov. are proposed. The type strains are YM10-847T (=MBIC08264T=DSM 18905T) and YM11-607T (=MBIC07778T=DSM 18904T), respectively.

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. (type strain KV-492T=NRRL B-24451T=NBRC 101280T).

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).

Type Strains

Three Gram-stain-positive strains were isolated from fermented mustard and were rod-shaped, non-motile, asporogenous, facultatively anaerobic, homofermentative and did not exhibit catalase activity. Comparative analyses of 16S rRNA, pheS and rpoA gene sequences demonstrated that the novel strains were members of the genus Lactobacillus. On the basis of 16S rRNA gene sequence analysis, the type strains of Lactobacillus crustorum (98.7 % similarity), Lactobacillus farciminis (98.9 %) and Lactobacillus mindensis (97.9 %) were the closest neighbours. However, DNA–DNA reassociation values with these strains were less than 50 %. Phenotypic and genotypic features demonstrated that these isolates represent a novel species of the genus Lactobacillus, for which the name Lactobacillus futsaii sp. nov. is proposed; the type strain is YM 0097T ( = JCM 17355T = BCRC 80278T).

Three Gram-positive, strictly anaerobic, non-spore-forming, rod-shaped organisms (strains YIT 12062T, YIT 12063T and YIT 12064) were isolated from human faeces. Strain YIT 12062T was asaccharolytic and possessed a DNA G+C content of 58.3 mol%. Cells of strain YIT 12062T were negative for catalase, oxidase, urease, hydrolysis of aesculin and gelatin, nitrate reduction and indole production. Based on 16S rRNA gene sequence analysis, strain YIT 12062T was assigned to the genus Slackia (91.7–96.0 % sequence similarities to type strains of Slackia species). Biochemical data showed that the isolate was phenotypically distinct from all recognized species of the genus Slackia. Strain YIT 12062T therefore represents a novel species in the genus Slackia, for which the name Slackia piriformis sp. nov. is proposed. The type strain is YIT 12062T (=DSM 22477T=JCM 16070T). Following 16S rRNA gene sequence analysis, strains YIT 12063T and YIT 12064, which were isolated from different subjects, were shown to be most closely related to species of the genus Collinsella (93.8–95.1 % similarities to type strains). Although their phenotypic characteristics were very similar and they shared >99 % 16S rRNA gene sequence similarity and >97±1.8 % DNA–DNA relatedness, the two isolates could be discriminated by RAPD fingerprints. The DNA G+C contents of strains YIT 12063T and YIT 12064 were 60.8 and 61.0 mol%, respectively. They were saccharolytic in API test systems, positive for aesculin hydrolysis and negative for catalase, oxidase, urease, indole production, nitrate reduction and gelatin hydrolysis. The major end products of glucose fermentation of these strains were lactate, acetate and formate. Biochemical data supported the affiliation of strains YIT 12063T and YIT 12064 to the genus Collinsella and showed that they were phenotypically distinct from all recognized species of the genus Collinsella. Strains YIT 12063T and YIT 12064 therefore represent a novel species of the genus Collinsella, for which the name Collinsella tanakaei sp. nov. is proposed. The type strain is YIT 12063T (=DSM 22478T=JCM 16071T).
