Abstract

A novel bacterial strain designated CB4 was isolated from soil from the Hallasan, Jeju, Korea. Strain CB4 was found to be strictly aerobic, Gram-stain-positive, rod-shaped, motile and formed creamy greyish colonies on nutrient agar. The major fatty acids were identified as iso-C and iso-C, and the predominant isoprenoid quinone as MK-7. The cell-wall peptidoglycan contained glycine and alanine as the diagnostic amino acids and phosphatidyl--methylethanolamine, phosphatidylethanolamine, diphosphatidylglycerol and an unidentified aminophospholipid as the polar lipids. The genomic DNA G+C content of strain CB4 was 46.5 mol%. Phylogenetic analysis, based on 16S rRNA gene sequence similarities, showed that strain CB4 forms a deep branch within the genus , sharing the highest level of sequence homology with DSM 5562 (96.5 %). On the basis of the phenotypic, chemotaxonomic and phylogenetic characteristics, strain CB4 is considered to represent a novel species within the genus , for which the name sp. nov. is proposed. The type strain is CB4 ( = KCTC 33505 = CECT 8566). An emended description of the genus is also proposed.
