sp. nov., isolated from coastal sediment.

A Gram-stain-negative, rod-shaped, facultative anaerobic bacterium, designated strain 3539, was isolated from coastal sediment of Weihai, PR China. Optimal growth occurred at 28 °C, pH 7.5-8.0 and in the presence of 3.0 % (w/v) NaCl. Results of phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 3539 formed a robust clade with members of the genus and was closely related to JCM 16154, F2 and sw153 with 97.7, 96.2 and 95.4 % sequence similarity, respectively. The average amino acid identity, percentage of conserved proteins, average nucleotide identity and digital DNA-DNA hybridization values between strain 3539 and JCM 16154 were 64.9, 68.3, 72.8 and 18.9 %, respectively. The genomic DNA G+C content of strain 3539 was 42.0 mol%. The dominant respiratory quinone was ubiquinone-8, and the major fatty acids were iso-C and summed feature 3 (C ω7/C ω6). The polar lipids of strain 3539 consisted of phosphatidyldimethylethanolamine, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, one unidentified aminophospholipid, one unidentified lipid and three unidentified phospholipids. Based on the combination of phylogenetic, phenotypic and chemotaxonomic data, strain 3539 is considered to represent a novel species within the genus in he family , for which the name sp. nov. is proposed. The type strain of the new species is 3539 (=KCTC 72414=MCCC 1H00388).
