Abstract
Lipases from Aspergillus niger and Rhizopus delemar catalyzed the synthesis of glycerides from oleic acid and glycerol. Lipases from Geotrichum candidum and Penicillium cyclopium were inactivated by oleic acid, but were stable in the presence of casein, albumin or buffer of appropriate pH. Lipases from A. niger and R. delemar synthesized glycerides from fatty acid, dibasic acids and aromatic acids, making ester bonds only at position 1 and 3 of glycerol. Lipases from G. candidum and P. cyclopium synthesized glycerides only from long chain fatty acids, and made ester bonds at all 3 available positions of the glycerol molecule.
