Abstract: A Gram-negative, aerobic bacterium, designated strain R-40503 T, was isolated from mucus of̃oChannel,SãoPaulo, Brazil. Phylogenetic analyses revealed that strain R-40503 T belongs to the genus Marinomonas. The 16S rRNA gene sequence similarity of R-40503 T was above 97% with the type strains of Marinomonas vaga, M. basaltis, M. communis and M. pontica, and below 97% with type strains of the other Marinomonas species. Strain R-40503 T showed less than 35% DNA-DNA hybridization (DDH) with the type strains of the phylogenetically closest Marinomonas species, demonstrating that it should be classified into a novel species. Amplified fragment length polymorphism (AFLP), chemotaxonomic and phenotypic analyses provided further evidence for the proposal of a novel species. Concurrently, a close genomic relationship between M. basaltis and M. communis was observed. The type strains of these two species showed 78% DDH and 63% AFLP pattern similarity. Their phenotypic features were very similar, and their DNA G+C contents were identical (46.3 mol%). Collectively, these data demonstrate unambiguously that Marinomonas basaltis is a later heterotypic synonym of Marinomonas communis. Several phenotypic features can be used to discriminate between Marinomonas species. The novel strain R-40503 T is clearly distinguishable from its neighbours. For instance, it shows oxidase and urease activity, utilizes L-asparagine and has the fatty acid C 12: 1 3-OH but lacks C 10: 0 and C 12: 0. The name Marinomonas brasilensis sp. nov. is proposed, with the type strain R-40503 T (5R-278 T 5LMG 25434 T 5CAIM 1459 T). The DNA G+C content of strain R-40503 T is 46.5 mol%. © 2011 IUMS Printed in Great Britain.
