Identification of ß-carotene producing bacteria from terrestrial habitats of Jaipur, Rajasthan

Carotenoids are pigments that have significant value as colorants and antioxidants in pharmaceutical, food, textile and cosmetic industries. Owing to its high demand, this study aims to identify s-carotene producing bacteria from different terrestrial habitats of Jaipur region.,In this paper, standard isolation and purification process was used, followed by colony morphology and biochemical characterization of s-carotene producing bacteria. s-carotene concentration was determined quantitatively using spectrophotometric method.,Out of 43 isolates, 21 isolates showed peak range between 400 and 500 nm confirming the presence of carotenoids. Only one bacteria SAN-A has capacity to produce s-carotene confirmed by the thin layer chromatography and high performance liquid chromatography (HPLC) with a yield of 1.68 mg/l. The 2, 2-Diphenyl-2-picrylhydrazil (DPPH) assay showed an IC50 value of 4.0 mg/ml.,The present study revealed the presence of s-carotene producing bacteria in the soil of different terrestrial habitat of Jaipur region which can be exploited as an economical source for s-carotene production.
