Figure 4: Effect of temperatures on the stability of the lipase. Relative activity of the lipase was measured at different interval at different temperature. (Open square) 20°C; (closed triangle) 30°C; (closed circle) 50°C; (closed square) 60°C; ° (open triangle) 70°C. The stability of the lipase was very high at 20°C, enzyme activity decreased slightly when temperature was at 30-40°C. Lipase activity was completely inactivated at 70°C at 120 mins.
