Abstract

Strain KV-677, a Gram-positive, aerobic, motile, rod-shaped bacterium, was isolated from park soil in Tokyo, Japan, and characterized. It grew well at 15–30 °C on nutrient agar and colonies were pale yellow. The cell-wall peptidoglycan contained diaminobutyric acid, glycine, alanine and glutamic acid and the muramic acid acyl type was acetyl. The predominant menaquinone was MK-12. Mycolic acids were not detected. The DNA G+C content was 70 mol%. 16S rRNA gene sequence analysis revealed that strain KV-677 fell within the cluster of the family and formed a separate lineage joining the genera , , and , showing 95.5–96.9 % sequence similarities with the type strains of the type species of the above genera. However, strain KV-677 clearly differed from these and other genera with relatively high sequence similarity in its chemotaxonomic characteristics. Therefore, it is proposed that strain KV-677 represents a novel species in a new genus, gen. nov., sp. nov., in the family . The type strain of is KV-677 (=NRRL B-24538 =NBRC 102123).
