sp. nov., a marine bacterium isolated from seawater of the Taiwan Strait in China Free

Abstract

A Gram-negative, ovoid rod-shaped bacterium that lacked bacteriochlorophyll , designated strain Y-2, was isolated from seawater of the Taiwan Strait, China. The strain was oxidase- and catalase-positive, and reduced nitrate to nitrite. Optimal growth occurred at around pH 7.0 and 25 °C in the presence of 1–3 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain Y-2 belonged to the class and formed a coherent cluster with SW-277 (96.2 % sequence similarity). The major whole-cell fatty acid was C 7 (75.42 %). Other characteristic fatty acids were C (9.16 %) and C (7.32 %). The DNA G+C content of strain Y-2 was 62.4 mol%. Therefore, based on phenotypic properties, phylogeny and genomic data, strain Y-2 should be placed in the genus as representing a novel species, for which the name sp. nov. is proposed. The type strain is Y-2 (=MCCC 1A00107=LMG 24574=CGMCC 1.7081).
