sp. nov., isolated from the gut microflora of a mussel, , and emended description of Free

Abstract

An orange-coloured and slender rod-shaped bacterium, designated strain PSC32, was isolated from the gut microflora of a mussel collected from Gwangyang Bay, South Sea (Republic of Korea). Cells were Gram-reaction-negative, strictly aerobic, and catalase- and oxidase-positive. The major fatty acids were iso-C, iso-C 3-OH, iso-C G and iso-C 3-OH. The only isoprenoid quinone of strain PSC32 was MK-6 and the DNA G+C content was 36.9 mol%. Phosphatidylethanolamine, one unidentified aminolipid and two unidentified polar lipids were found as major polar lipids. A phylogenetic tree based on 16S rRNA gene sequences showed that strain PSC32 forms an evolutionary lineage within the genus and is closely related to A6 (97.0 % similarity) and to other members of the genus (94.4–96.5 %). Genomic DNA–DNA relatedness between strain PSC32 and A6 was 40.7 %. A number of phenotypic characteristics distinguished strain PSC32 from described members of the genus . On the basis of the evidence presented in this study, strain PSC32 represents a novel species, for which the name sp. nov. is proposed. The type strain is PSC32 ( = KCTC 23301 = JCM 17453). An emended description of is given.
