Abstract

Four bacterial strains were isolated from larval cultures and collectors of the scallop . They showed a high level of intragroup genomic relatedness (84–95%) as determined by DNA-DNA hybridization. The cells were Gram-negative, strictly aerobic, motile, ovoid rods. They grew at temperatures from 15 to 37 °C and from pH 7·0 to 10, but did not grow in the absence of NaCl and required growth factors. They had the ability to use a wide variety of compounds as sole carbon source: D-mannose, D-galactose, D-fructose, D-glucose, D-xylose, melibiose, trehalose, maltose, cellobiose, sucrose, -erythritol, D-mannitol, glycerol, D-sorbitol, -inositol, succinate, propionate, butyrate, γ-aminobutyrate, DL-hydroxybutyrate, 2-ketoglutarate, pyruvate, fumarate, glycine, L-α-alanine, β-alanine, L-glutamate, L-arginine, L-lysine, L-ornithine and L-proline. They exhibited oxidase and catalase activities but no denitrification activity. The isolates did not contain bacteriochlorophyll a. The G+C content ranged from 57·6 to 58 mol%. Phylogenetic analyses of the 16S rRNA sequence revealed that these isolates belong to the genus . On the basis of quantitative hybridization data, it is proposed that these isolates should be placed in a new species, . The type strain is BS107(= CIP 105210).
