Thirty halophilic bacteria were isolated from the soil of Karwar mangrove regions, Karnataka. These were examined for the production of pigments, antibiotic and proteolytic activities. KA16SPiv produced fluorescent green pigment and KA16SK2HS produced pink pigment. The optimal pigment production was at pH 8, 37°. Pigments are extractable in chloroform and methanol. Absorption spectra suggested phenazine skeleton for green and prodigiosin skeleton for pink pigment. A polyphasic taxonomic study showed KA16SPiv to be Pseudomonas aeruginosa whereas KA16SK2HS to be Salinicoccus roseus with accession no: MF377544 and MF377542, respectively.
