sp. nov., a gammaproteobacterium isolated from the sea urchin Free

Abstract

A strictly aerobic, Gram-stain-negative, rod-shaped, non-motile and yellow-pigmented bacterial strain, designated KMM 6208, was isolated from a sea urchin. Phylogenetic analysis based on 16S rRNA gene sequencing revealed that this novel isolate was affiliated to the class and formed a robust cluster with KMM 3895 with 98.2 % 16S rRNA gene sequence similarity. Strain KMM 6208 grew in the presence of 0.5–5 % NaCl and at a temperature range of 4–38 °C. The isolate was oxidase-positive and hydrolysed aesculin, casein, chitin, gelatin, starch and Tweens 40 and 80. The prevalent fatty acids of strain KMM 6208 were Cω7, iso-C iso-C Cω7 and C The polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and an unidentified aminophospholipid, and the major isoprenoid quinone was Q-8. The DNA G+C content of strain KMM 6208 was 46.3 mol%. The DNA–DNA relatedness value of strain KMM 6208 with KMM 3895 was 5 %. Molecular data in a combination with phenotypic findings strongly suggest inclusion of this novel strain in the genus as a representative of a novel species for which the name sp. nov. is proposed. The type strain is KMM 6208 ( = KCTC 12711 = LMG 26983).
