Jatrophihabitans soli sp. nov., isolated from soil

Abstract

One bacterial strain, designated KIS75-12T, isolated from a soil sample collected from Wonsando island located in Boryeong city, Republic of Korea, was characterized as aerobic, Gram-stain-positive, non-flagellated and a short rod. It grew between temperatures of 15–37 °C, pH 4–9 and 0–3.0 % (w/v) NaCl. The 16S rRNA gene analysis showed the strain was moderately related to Jatrophihabitans endophyticus S9-650T (97.7 %) and revealed low sequence similarity (≤94.7 %) with all the other species with validly published names. Its major fatty acid was iso-C16 : 0. The predominant menaquinone of strain KIS75-12T was MK-9(H4). The polar lipids consisted of diphosphatidylglycerol and several small amounts of phosphatidylinositol, aminolipids and glycolipid. The peptidoglycan contained meso-A2pm as diagnostic diamino acid and the peptidoglycan type is A4γ. The genomic DNA G+C content of the type strain was 72.1 mol%. The combined phenotypic, chemotaxonomic and phylogenetic data showed that strain KIS75-12T could be clearly distinguished from the only member of the genus Jatrophihabitans , J. endophyticus . Therefore, the results of this study indicate the existence of a representative of a novel species of the genus Jatrophihabitans , for which we propose the name Jatrophihabitans soli sp. nov., with strain KIS75-12T ( = KACC 17298T = DSM 45908T  =  NBRC 109658T) as the type strain. An emended description of the genus Jatrophihabitans is also given.
