Figure 2: Effects of different triacylglycerol sources (a) and poultry fat concentration (b) on lipase production by C. viswanathii in solid-state cultivation. Cultures were carried out with wheat bran plus barley spent grain supplemented with 25% (w/w) of each triacylglycerol source without nitrogen source supplementation and 50% (w/v) initial moisture provided by Vogel salts solution, at 28°C for 5 days (a). Cultures were carried out in the same conditions with only poultry fat (b). ■: lipase production (U/gds); □: specific activity (U/mg of protein).
