Abstract

A yellow-pigmented, non-motile, Gram-stain-negative, rod-shaped bacterium, designated II4 was obtained from soil sampled at Seongnam, Gyeonggi-do, Republic of Korea. Cells were strictly aerobic, grew optimally at 20–28 °C and hydrolysed casein. A phylogenetic analysis based on its 16S rRNA gene sequence revealed that strain II4 formed a lineage within the family and clustered as members of the genus . The closest members were THG-A13 (97.88 % sequence similarity), GH34-4 (97.82 %), YC6269 (97.74%), GH19-3 (97.53 %) and ATCC 29487 (96.18 %). The principal respiratory quinone was Q-8 and the major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The predominant cellular fatty acids were summed feature 9 (C 10-methyl and/or iso-C 9) and iso-C and iso-C. The DNA G+C content was 68.2 mol%. The average nucleotide identity and DNA–DNA hybridization relatedness values between strain II4 and its closely related genus members with possible full genome sequences were ≤79.6 and 23.7 %, respectively. Based on genomic, chemotaxonomic, phenotypic and phylogenetic data, strain II4 represents novel species in the genus , for which the name sp. nov. is proposed. The type strain is II4 (=KACC 21196=NBRC 113956).
