Abstract

Thirteen yellow pigment producing bacterial strains were isolated by air and soil sampling method and screened for carotenoid production, as many of them exhibited a deep orange pigmentation when cultured on NA-plates. We found that most of them produced trace amount of carotenoids. The isolates RS7, RSS3, RS13 and RS14 had significant amounts of the yellow pigment producing ability (Degree of pigmentation 8.31, 2.72, 6.66 and 5.5). Free Radical Scavenging Activity of the extracts from the isola
