Two aerobic, gram-negative asporogenous, red-pigmented, rod-shaped bacterial strains were isolated from oil sardine (Sardinella longiceps). Their morphological, biochemical and growth characteristics are reported. The pigment was identified to be a prodigiosene. The strains were found to resemble Serratia plymuthica. Effect of temperature and certain carbohydrates on pigmentation was also studied. Iron was found to inhibit pigmentation, and mannitol or sorbitol removed such inhibition.
