Abstract

A taxonomic study was performed on strain MSL-08, which was isolated from a soil sample collected from Bigeum Island. The novel isolate was aerobic and Gram-positive. Cells were short and motile rods. Growth temperature ranged from 20 to 28 °C and the pH for growth ranged from 6.5 to 12.0. The optimum growth temperature and pH were 28 °C and 7.3, respectively. The predominant menaquinone was MK-9. Cell wall analysis showed B-type peptidoglycan containing 2,4-diaminobutyric acid, alanine, glycine, glutamate and lysine. The diagnostic phospholipids were diphosphatidylglycerol and phosphatidylglycerol. The major fatty acids were ai-C, i-C, C 7 and ai-C. The DNA G+C content was 67.5 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain MSL-08 had less than 97 % similarity to any recognized species of the genus . DSM 10309 was found to be the closest neighbour (96.95 %) to the novel strain. Based on the 16S rRNA gene sequence analysis and phenotypic characteristics, it is proposed that strain MSL-08 represents a novel member of the genus for which the name sp. nov. is proposed. The type strain is MSL-08 (=DSM 19442=KCTC 19311).
