Abstract/OtherAbstract:
|
The hydrolysis of effluent from a poultry slaughterhouse containing 800mg oil and grease (O&G)/L was conducted with 1% (w/v) of an enzymatic pool obtained by solid-state fermentation with the fungus Penicillium restrictum. The chromatographic evaluation of the lipid profile during hydrolysis indicated a higher concentration of acids after 4h of reaction (2954mg/L), with a predominance of oleic, palmitic, and linoleic acids. Effluent aliquots were collected after 4, 8, and 24h of hydrolysis and tested for anaerobic biodegradation in sequential batches. An adaptation of the biomass was observed, both in the control experiment (with non-hydrolyzed raw effluent) and in the experiments with enzymatically pre-treated effluent. The specific methane production in the control experiment was 0.248L CH(4)/g COD(consumed), and in the experiment with effluent pre-treated for 4h, this production was 0.393L CH(4)/g COD(consumed), indicating a higher methane production after enzymatic hydrolysis. |
