In vitro antioxidant and antimicrobial activity of carotenoid pigment extracted from Sporobolomyces sp. isolated from natural source
Journal Title: Journal of Applied and Natural Science - Year 2014, Vol 6, Issue 2
Abstract
The aim of the present study was to isolate and study about the antioxidant and antibacterial activity of carotenoid pigment. Sporobolomyces sp. isolated from the phyllosphere surface of rice plant has found to produce carotenoid pigment. The present investigation was carried out for antioxidant assays viz., DPPH, iron reducing and metal chelating activity. A steady increase in the antioxidant activities was observed in the carotenoid pigment with raising the pigment concentration. In the present study, the maximum antioxidation characteristics of carotenoid by DPPH, iron reducing and metal chelating assays (75.04 %, 1.88 % and 59.32 %) were achieved by pigmentation of Sporobolomyces sp. at the concentration of 100 μg ml-1. The antibacterial activity was studied on several organisms like Enterococcus sp., Staphylococcus aureus, Streptococcus faecalis, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa. Among the six pathogens, the pigment was found to be more effective against E. coli (2.9 cm) and S. aureus (2.6 cm). This study revealed that yeast carotenoid pigment was a potential source for its use in food and pharmaceutical applications.
