| Abstract |
A strictly aerobic, Gram-stain-negative, rod-shaped, non-motile and yellow-pigmented bacterial strain, designated KMM 6208(T), was isolated from a sea urchin. Phylogenetic analysis based on 16S rRNA gene sequencing revealed that this novel isolate was affiliated to the class Gammaproteobacteria and formed a robust cluster with Arenicella xantha KMM 3895(T) with 98.2% 16S rRNA gene sequence similarity. Strain KMM 6208(T) grew in the presence of 0.5-5% NaCl and at a temperature range of 4-38 degrees 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(T) were C-16:1 omega 7c, iso-C-16:0, iso-C-18:0, C-18:1 omega 7c and C-16:0. 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(T) was 46.3 mol%. The DNA DNA relatedness value of strain KMM 6208(T) with Arenicella xantha KMM 3895(T) was 5%. Molecular data in a combination with phenotypic findings strongly suggest inclusion of this novel strain in the genus Arenicella as a representative of a novel species for which the name Arenicella chitinivorans sp. nov. is proposed. The type strain is KMM 6208(T) (=KCTC 12711(T)=LMG 26983(T)). |
