Abstract

A Gram-negative, aerobic, motile by gliding, and rod-shaped marine bacterium, designated CE67T was isolated from the marine sponge Callyspongia elegans on Biyang-do in Jeju Island. The CE67T strain grew optimally at 25℃, pH 7.5, and in the presence of 2-3% (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain CE67T was related to the genus Aureivirga and had the highest 16S rRNA gene sequence similarity to the Aureivirga marina VIII.04T type strain (96.3%). The primary fatty acids (>10%) of strain CE67T were iso-C15:0 (35.3%) and iso-C17:0 3OH (21.8%). The polar lipid profile of strain CE67T contained phosphatidylethanolamine, unidentified aminolipids, and unidentified lipids. The predominant menaquinone was MK-6. The DNA G+C content was 29.1 mol%. Based on the polyphasic taxonomic analysis, strain CE67T was determined to be a representative novel species of the genus Aureivirga for which we propose the name Aureivirga callyspongiae sp. nov., whose strain type is CE67T (=KCTC 42847T=JCM 34566T).
