Catalytic and physical features of a naturally immobilized lipase in cell debris (LipImDebri) displaying high thermostability.

Lipase activity (337 U/g dry weight of cell debris) was detected in cell debris after ultrasound treatment of cells cultivated in residual frying palm oil. It is a naturally immobilized lipase with protein content of 47%, herein called LipImDebri. This immobilized biocatalyst presents low hydrophobicity (8%), that can be increased adjusting pH and buffer type.
