sp. nov., an exopolysaccharide-producing acidobacterium isolated from rhizosphere soil of a medicinal plant Free

Abstract

An exopolysaccharide-producing bacterium, designated strain DRP 35, was isolated from the rhizosphere soil of a medicinal herb, at Geumsan in Korea. Cells were Gram-staining-negative, non-motile, catalase-positive and oxidase-negative short rods. The isolate grew aerobically from 15 to 45 °C (optimum 30 °C), pH 3.5–7.0 (optimum pH 5.0) and in the presence of 0–1.0 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain DRP 35 belongs to the genus in the phylum with a sequence similarity of 97.2 % and 97.0 % to SP1PR4 and KBS63, respectively. The genomic DNA G+C content was 62.1 mol%. DNA–DNA relatedness between strain DRP 35 and the type strains of the other species of the genus SP1PR4 and KBS63, were 24.6 and 17.2 %, respectively. The predominant menaquinone was MK-8. Major fatty acids were iso-C, Cω7 and C. The polar lipids were phosphatidylethanolamine, unidentified aminophospholipid and unknown phospholipids. On the basis of polyphasic analysis from this study, strain DRP 35 represents a novel species of the genus for which the name Terriglobus sp. nov. is proposed. The type strain is DRP 35 ( = KACC 16474 = NBRC 109677).
