Description The novel, cream colored, Gram-staining-negative, rod-shaped, motile bacteria, designated strains AK15 sup(T) and AK18, were isolated from sediment samples collected from Palk Bay, India. Both strains were positive for arginine dihydrolase, lysine decarboxylase, oxidase, nitrate reduction and methyl red test. The major fatty acids were C sub(16:0), C sub(18:1 ?7c), C sub(16:1 ?7c) and/or C sub(16:1 ?6c) and/or iso-C sub(15:0) 2-OH (summed feature 3). Polar lipids content of strains AK15 sup(T) and AK18 were found to bephosphatidylethanolamine (PE), two unidentified phospholipids (PL1 and PL2) and three unidentified lipids (L1-L3). The 16S rRNA gene sequence analysis indicated strains AK15 sup(T) and AK18 as the members of the genus Photobacterium and closely related to the type strain Photobacterium jeanii with pair-wise sequence similarity of 96.7 percent. DNA-DNA hybridization between strain AK15 sup(T) and AK18 showed a relatedness of 87 percent. Based on data from the current polyphasic study, strains AK15 sup(T) and AK18 are proposed as novel species of the genus Photobacterium, for which the name Photobacterium marinum sp. nov. is proposed. The type strain of Photobacterium marinum is AK15 sup(T) (=MTCC 11066 sup(T) = DSM 25368 sup(T)).
