Simultaneous enzymatic hydrolysis and anaerobic\r\nbiodegradation of lipid-rich wastewater from poultry\r\nindustry with porcine pancreatic lipase at different concentrations\r\n(from 1.0 to 3.0 g L-1) were performed. The\r\nefficiency of the enzymatic pretreatment was measured by\r\nthe Chemical Oxygen Demand (COD) removal and formation\r\nof methane. All samples pretreated with lipase\r\nshowed a positive effect on the COD removal and formation\r\nof methane. After 30 days of anaerobic biodegradation\r\nthe methane production varied from 569 �± 95 to\r\n1,101 �± 10 mL for crude wastewater and pretreated at\r\n3.0 g L-1 enzyme, respectively. COD removal of wastewater\r\nsupplemented at different enzyme concentrations\r\nwas found to be threefold higher than crude wastewater.\r\nThe use of lipases seems to be a promising alternative for\r\ntreating lipid-rich wastewaters such as those from the\r\npoultry industry.
