sp. nov., isolated from marine sediment Free

Abstract

A novel bacterial strain, designated Y11, was isolated from marine sediment at Weihai in China. Comparative analysis of 16S rRNA gene sequences demonstrated that the novel isolate showed highest similarity to DSM 9555 (94.0 %) and SS12 (92.7 %). Strain Y11 was a Gram-stain-negative, rod-shaped, non-endospore-forming, yellow-pigmented bacterium and was able to hydrolyse agar weakly. It was catalase-negative, oxidase-positive, facultatively anaerobic and motile by gliding. Optimal growth occurred at 28–30 °C, at pH 7.0–7.5 and in the presence of 2–3 % (w/v) NaCl. The DNA G+C content was 34.4 mol%. The strain contained MK-7 as the prevalent menaquinone. The major cellular fatty acids were iso-C, anteiso-C and Cω6. The predominant polar lipids were phosphatidylethanolamine and two unknown lipids. Data from the present polyphasic taxonomic study clearly place the strain as representing a novel species within the genus , for which the name sp. nov. is proposed. The type strain is Y11 ( = CICC10837 = KCTC42400).
