Characterization of carotenoids extracted from Haloferax larsenii NCIM 5678 isolated from Pachpadra salt lake, Rajasthan.
Carotenoids are a diverse group of pigments known for their broad range of biological functions and applications. This study delves into multifaceted potential of carotenoids extracted from Haloferax larsenii NCIM 5678 previously isolated from Pachpadra Salt Lake in Rajasthan, India. H. larsenii NCIM 5678 was able to grow up to OD600 1.77 ± 0.03 with carotenoid concentration, 3.3 ± 0.03 µg/ml. The spectrophotometric analysis of carotenoid extract indicated the presence of three-fingered peak (460, 490 and 520 nm) which is a characteristic feature of bacterioruberin and its derivatives. The bacterioruberin was purified using silica gel column chromatography and thin layer chromatography. The carotenoid extract showed 12.3 ± 0.09 mm zone of growth inhibition with a minimum inhibitory concentration 546 ng/ml against indicator strain, H. larsenii HA4. The percentage antioxidant activity of carotenoid was found to be 84% which was higher as compared to commercially available ascorbic acid (56.74%). Thus, carotenoid extract from H. larsenii NCIM 5678 possesses unique attributes with compelling evidence of antimicrobial and antioxidant potential for the development of novel pharmaceuticals and nutraceuticals.
