Agroindustrial Wastes as Alternative for Lipase Production by Candida viswanathii under Solid-State Cultivation: Purification, Biochemical Properties, and Its Potential for Poultry Fat Hydrolysis

Table 2

Lipase production by C. viswanathii in solid-state cultivation with different nitrogen sources.

Nitrogen sources (5% w/w)	Lipase activity (U/gds)	Specific activity (U/mg prot)
Control	31.43 ± 4.91	11.64 ± 1.81
Yeast extract	119.91 ± 11.68	65.50 ± 6.38
Corn steep liquor	57.96 ± 5.20	49.32 ± 5.35
Whey powder	61.00 ± 4.20	93.53 ± 6.44
Soybean meal	40.65 ± 4.80	24.12 ± 4.03
Soy protein	84.60 ± 4.41	76.22 ± 7.62
Cotton seed protein	57.95 ± 2.83	66.84 ± 3.72

Cultures were carried out on wheat bran plus barley spent grain (1 : 1, w/w), 50% moisture, and 40% (w/w) poultry fat for 5 days, at 28°C. Control was carried out in the absence of nitrogen source.
