Abstract:

Microorganisms produce certain commercially important secondary metabolites like antibiotics, carotenoid pigments, toxins and so on, some of which are of commercial importance. Carotenoid is a group of pigment and its production is a natural phenomenon in case of certain microorganisms. Yeast is a unicellular eukaryotic organism occurring in soil, air, feed and fodder of dairy farm environment. Among yeast, Rhodotorula sp. produces both extra and intracellular carotenoid pigments. The pigment producing 11 isolates of Rhodotorula were obtained from air (3), apple (4), can milk (2) and yoghurt (2). Phenotyped Rhodotorula minuta RAI3; Rhodotorula acheniorum RC2, Rhodotorula sp RA2, Rhodotorula minuta RY1 were selected for pigment production. Sterile synthetic media Malt Yeast Extract Agar (MYEB), coconut water as liquid media and rice as solid substrate medium were used for intracellular pigment production from Rhodotorula minuta RAI3; Rhodotorula acheniorum RC2, Rhodotorula sp RA2, Rhodotorula minuta RY1. Coconut water and rice media showed maximum production of intracellular pigment at 300C for 6 days. Among the 4 isolates, Rhodotorula minuta RAI3 showed maximum intracellular pigment production of 4.412 μg/g of dry cell mass respectively. The present study was taken to the production and characterization of pigments from wild strains of phenotyped Rhodotorula sp.
