Abstract

A Gram-staining-negative bacterial strain, designated CJ42, was isolated from ginseng soil in Anseong, Republic of Korea. Cells were rod-shaped, yellow-pigmented, aerobic and devoid of flagella but showed gliding motility. Strain CJ42 grew optimally at 30 °C and pH 7.0 in the absence of NaCl on tryptic soy agar. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain CJ42 belonged to the genus Flavobacterium within the family Flavobacteriaceae and was most closely related to Flavobacterium tistrianum KCTC 42679 (97.3 % similarity). Flexirubin-type pigments were produced. The only respiratory quinone was menaquinone 6. The predominant polar lipids were phosphatidylethanolamine, an unknown aminolipid and two unknown lipids. The major fatty acids of strain CJ42 were iso-C15 : 0 and summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c). The G+C content of the genomic DNA was 30.7 mol%. Based on the polyphasic analyses, strain CJ42 represents a novel species in the genus Flavobacterium , for which the name Flavobacterium foetidum sp. nov. is proposed. The type strain is CJ42 (=KACC 19302=JCM 32085).
