Fermentative production of carotenoids from marine actinomycetes
Background and Objectives: In marine actinomycetes, carotenoid production occurs in constitutive, light-dependent or cryptic manner. The present work deals with the fermentative production of carotenoids from marine actinomycetes.
Materials and Methods: Marine actinomycetes namely Streptomyces strain AQBMM35 was isolated from the marine sponge Mycale mytilorum collected from South West coast of India using ISP media. The Streptomyces isolates were characterized for their colony characteristics, morphological properties, physiological and biochemical properties and were tentatively identified. Fermentation of the strain under fluorescent white light was carried out for the production of carotenoids. UV spectrum, TLC and HPLC analysis were done for the confirmation of carotenoids.
Results: The characteristics studied strongly suggest that the strain AQBMM35 belongs to the genus Streptomyces sp. It has been found that Streptomyces strain (AQBMM35) fermenting under fluorescent white light produced carotenoids. Spectrophotometric analysis of the carotenoid fraction revealed a peak at 280 nm. TLC analysis of the carotenoid extract showed the presence of phytoene (Rf of 0.81). HPLC confirmed the production of phytoene when compared with standards.
Conclusion: The fermenting sponge-associated Streptomyces isolate (AQBMM35) produced carotenoids namely phytoene. If this symbiotic Streptomyces strain, from which secondary metabolite like carotenoids are derived, can be cultured under light, then it can be used for mass production of precursor pigment and it can be used as an antioxidant and also as a food additive.
