Whole-cell fatty acid methyl ester analysis indicated that the isolates belonged to the class Gammaproteobacteria and were closely related or belonging to the genus Alteromonas . Genomic fingerprinting using the BOX-PCR primer delineated five clusters of isolates with similar BOX-PCR fingerprints. This study demonstrated that isolates from four of the BOX-PCR clusters belonged to Alteromonas macleodii and that the 14 isolates representing BOX-PCR cluster 1 constituted a novel species, which shared 98.4 % 16S rRNA gene sequence similarity with its nearest phylogenetic neighbour, Alteromonas hispanica . Both phenotypic and genotypic analyses enabled this novel species, for which the name Alteromonas genovensis sp. nov. is proposed, to be differentiated from established species of the genus Alteromonas . The DNA G+C content of Alteromonas genovensis sp. nov. is 44.5 mol% and the type strain is LMG 24078 T (=CCUG 55340 T ). The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA gene sequences of strains LMG 24078 T , LMG 24079, LMG 24080, LMG 24081, LMG 24082 and LMG 24083 are AM885866 , AM887686 , AM885868 , AM885867 , AM885870 and AM887685 , respectively. DNA–DNA hybridization results and additional electron micrographs are available with the online version of this paper.
