Six strains of Gram-negative, rod-shaped, non-spore-forming bacteria were isolated from the Mediterranean Sea. 16S rRNA gene sequence analysis indicated that the strains were affiliated within the alphaproteobacterial genus Brevundimonas, with Brevundimonas intermedia (99.4 %) and Brevundimonas vesicularis (99.2 %) as their closest relatives. This affiliation was supported by chemotaxonomic data (major polar lipids: phosphatidyl diacylglycerol, sulfoquinovosyl diacylglycerol and phosphatidyl glucopyranosyl diacylglycerol; major fatty acids: C(18 : 1), C(16 : 0), C(16 : 1), C(15 : 0), C(17 : 1)omega8c, 11-Me-C(18 : 1)omega5t). The results of DNA-DNA hybridization and physiological and biochemical tests allowed genotypic and phenotypic differentiation of the strains from all recognized Brevundimonas species. The strains therefore represent a novel species, for which the name Brevundimonas mediterranea sp. nov. is proposed, with the type strain V4.BO.10T)(=LMG 21911T=CIP 107934T).
