Characterization of a thermo tolerant lipase from Pichia anamola

Prakash Tiwari and Mukesh K. Upadhyay

A yeast strain of Pichia anamola was characterized for optimal production of liapse.The organism shown maximum enzyme production on 5th day of incubation. The optimum temperature and pH for th e enzyme activity was 45°C and 7.0 respectively. The enzyme r e t a i n e d 85 % activity at 55°C. Few metal ions like Ca⁺² and Mg⁺²enhanced the activity whereas Fe⁺³, Hg⁺²and Ag⁺ declined the enzyme action. The enzyme was characterized by some inhibitors and solvents; amongst inhibitors, β – mercapto ethanol, SDS and urea had shown maximum inhibition where as amongst the solvents phenol and chloroform strongly repressed the activity.
