摘要: Abstract Lipases are particularly important due to the fact that they specifically hydrolyze acylglycerols into free fatty acids and glycerol, which is of greater interest for biodiesel production. In this study, garbage lipase was produced from organic waste (Pomegranate (P), Orange (O) Pineapple (PA) peels) by optimization composition, ultrasonic pre-treatment time process parameters. Optimization parameters using RSM ANN modelling performed with composition 35(P): 20(O): 35(PA) 15 min (pre-treatment). The maximum activity 57.43 U/mL obtained at pH (6), temperature (33 °C), agitation (210 rpm) (4 days). effects pH, temperature, solvents on stability partially purified (PPL) enzyme kinetic were also investigated. PPL yielded 88.63% conversion palm oil biodiesel. Hence, would be a potential biocatalyst other industrial catalytic processes.
