sp. nov., isolated from forest soil.

A novel bacterial strain, designated ysch24, was isolated from a forest soil sample collected from the Cat Tien National Park, southern Vietnam. Cells were Gram-stain-negative, aerobic, gliding, filamentous or rod-shaped. The results of 16S rRNA gene analyses revealed that strain ysch24 belongs to the genus , and was most closely related to GDMCC 1.1411 (97.4 %), followed by JCM 16595 (97.3 %) and NBRC 15057 (96.9 %). The average nucleotide identity and digital DNA-DNA hybridization values between strain ysch24 and closely related type strains were 72.0-74.0 % and 19.1-19.4 %, respectively. Major fatty acids were iso-C, C ω5 and iso-C 3-OH and the predominant respiratory quinone was menaquinone 7. Polar lipids consisted of phosphatidylethanolamine, four unidentified aminophospholipids, two unidentified phospholipids and four unidentified lipids. The genomic DNA G+C content was 45.6 mol%. The study clearly showed that strain ysch24 should represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is ysch24 (=GDMCC 1.1355=KACC 21527).
