Pigmented pseudoalteromonas sp. isolated from marine sponge with anti-microbial activities against selected human pathogens

Marine sponges have been the potential source of bioactive compounds with potent antimicrobial properties. Sponge associated microbes significantly provide the route of biosynthesis of some of these compounds. In this work, a total of 100 bacterial colonies were screened from a marine sponge from Cl...
