Abstract
A Gram-stain-negative, aerobic, non-motile and rod-shaped bacterium, designated KIS59-12T, was isolated from a soil sample collected on Hodo island, Boryeong, Republic of Korea. The strain grew at 10–33 °C, pH 6.0–7.5 and with 0–4 % NaCl (w/v). Results of phylogenetic analysis based on 16S rRNA gene sequences showed that strain KIS59-12T was in the same clade as Arachidicoccus rhizosphaerae Vu-144T and Arachidicoccus ginsenosidivorans Gsoil809T with 97.5 and 97.2 % sequence similarity, respectively. Comparative genome analysis between strain KIS59-12T and A. rhizosphaerae Vu-144T showed that average nucleotide identity value was 69.4 % and the digital DNA–DNA hybridization value was 19.1 %. The major respiratory quinone was menaquinone-7. The major polar lipids were phosphatidylethanolamine and an unknown polar lipid. The predominant cellular fatty acids were iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH, which supported the affiliation of strain KIS59-12T with the genus Arachidicoccus . The major polyamines were homospermidine and putrescine. The genomic DNA G+C content was 36.4 mol%. On the basis of phylogenetic, physiological and chemotaxonomic characteristics, strain KIS59-12T represents a novel species of the genus Arachidicoccus , for which the name Arachidicoccus soli sp. nov. is proposed. The type strain of Arachidicoccus soli is KIS59-12T (=KACC 17340T=NBRC 113161T).
