Figure 3: Effect of yeast extract concentration 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 and 50% (w/v) initial moisture provided by Vogel salts solution, at 28°C for 5 days. ■: lipase activity (U/gds); □: specific activity (U/mg of protein).
