Influence of Agro wastes on Enhanced Carotenoid Production – An Untapped Resource from Tropical Wetland Actinobacterial Cell Factory for Multifunctional Prospectives

Abstract

The environmental toxicity problems caused by synthetic dyes, have incited the need for expedition of natural pigments or biochromes. Henceforth, microbial pigments can dwell as a promising alternative for synthetic colorants. In the current study, an extracellular yellow carotenoid was isolated from tropical mangrove wetland sediment. An actinomycete isolate, producing a characteristic extracellular yellow carotenoid, was attributed to be Streptomyces coelicolor strain SPR7 by 16SrDNA sequencing. The influence of agro wastes on Carotenoid production was scrutinized. The purified pigment was characterized by UV-Vis spectroscopy, FTIR and GC-MS; bioprospected for distinct applications such as antimicrobial activity, antioxidant activity and textile applications post to silica gel G60 chromatography. The obtained results leaded the yellow carotenoid to accept as natural dye and displayed a prospective antibacterial coupled antioxidant activity along with textile dying attributes. Ultimately, the present study could be a progressive streamline for sophisticated research and scopes in the distinct industrial arena scale.
