A carotenoid pigment present in red yeast and they possess a wide range of antimicrobial activity. The aim of the present study was tostudy about the antibacterial activity of carotenoid, extracted from soil pigmented yeast. Yeast strain Rhodotorula mucilaginosa YP 187 was isolated from the soil sample collected from Tiger reserve, Parambikulam, Kerala, India. The antibacterial activity of carotenoid pigment was studied on several organisms like Bacillus Subtilis, Streptococcus faecalis, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Enterococcus sp. The pigment showed excellent antibacterial activity than the standard chloramphenicol. Among this, pigment showed maximum inhibition against Bacillus subtilis and Staphylococcus aureus.
