Abstract

A novel Gram-stain-negative, non-motile, halophilic bacterium designated strain M10.9X was isolated from the inner sediment of an aluminium can collected from the Mediterranean Sea (València, Spain). Cells of strain M10.9X were rod-shaped and occasionally formed aggregates. The strain was oxidase-negative and catalase-positive, and showed a slightly psychrophilic, neutrophilic and slightly halophilic metabolism. The phylogenetic analyses revealed that strain M10.9X was closely related to E-37 and F028-2. The genomic G+C content of strain M10.9X was 65.2 mol%. The average nucleotide identity and digital DNA–DNA hybridization values were 76.6 and 20.9 %, respectively, confirming its adscription to a new species within the genus . The major cellular fatty acids were C ω7/C ω6 and C. The polar lipids consisted of phosphatidylglycerol, phosphatidylethanolamine, an unidentified aminolipid, an unidentified glycolipid, an unidentified phospholipid and an unidentified lipid. According to the resuts of a polyphasic study, strain M10.9X represents a novel species of the genus for which the name sp. nov. (type strain M10.9X=DSM 112301=CECT 30307) is proposed.
