Abstract

|
A non-motile and rod shaped bacterium, designated strain B1T, was isolated from forest soil at Mt. Baekwoon, Republic of Korea. Cells were Gram-negative, catalase-positive, and oxidase-negative. The major fatty acids were 9-octadecenoic acid (C18:1 ω9c; 42%) and hexadecanoic acid (C16:0; 25.9%) and summed feature 3 (comprising iso-C15:0 2-OH and/or C16:1 ω7c; 10.0%). The DNA G+C content was 44.1 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain B1T formed a lineage within the genus Acinetobacter and was closely related to A. baylyi DSM 14961T (98.6% sequence similarity), followed by A. baumannii DSM 30007T (97.4%), A. calcoaceticus DSM 30006T (97.0%), and 3 genomic species (96.8~7.6%). Phenotypic characteristics, gyrB gene sequence analysis and DNA-DNA relatedness data distinguished strain B1T from type strains of A. baylyi, A. baumannii, and A. calcoaceticus. On the basis of the evidence presented in this study, strain B1T represents a novel species of the genus Acinetobacter, for which the name Acinetobacter soli sp. nov. is proposed. The type strain is B1T (= KCTC 22184T= JCM 15062T).
