Abstract

A Gram-stain-negative, non-motile, rod-shaped bacterial strain, designated KIS14-15, was isolated from forest soil of Baengnyeong Island in the Yellow Sea in Korea and its taxonomic position was investigated by using a polyphasic study. Strain KIS14-15 grew optimally at 30 °C, at pH 6.0–7.0 and without NaCl. In the neighbour-joining phylogenetic tree based on 16S rRNA gene sequences, strain KIS14-15 formed a cluster with the strains of with a bootstrap resampling value of 100 %. Strain KIS14-15 exhibited 16S rRNA gene sequence similarity values of 98.0 % to 521 and of less than 89 % to the type strains of other taxa. The mean level of DNA–DNA relatedness between strain KIS14-15 and KACC 16548 was 21 % (reciprocal, 24 %). The predominant ubiquinone found in strain KIS14-15 and KACC 16548 was ubiquinone-10 (Q-10). The predominant fatty acids of strain KIS14-15 and KACC 16548 were Cω7, C 2-OH and 11-methyl Cω7. Total polar lipids of strain KIS14-15 were phosphatidylmonomethylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, one unknown aminolipid and one unknown lipid. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, demonstrated that strain KIS14-15 is distinguishable from . On the basis of the data presented, strain KIS14-15 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is KIS14-15 ( = KACC 13034 = NBRC 108950).
