Light Induced Esterification of Oleic Acid Catalyzed by Pseudomonas Cepacia Lipase

This paper reports on new approach of light illuminated esterification of oleic acid catalyzed by an enzymatic catalyst. Immobilized Pseudomonas cepacia lipase was used as a biocatalyst. Enzyme catalyzed esterification reaction was chosen due to the wide attention from chemical and biotechnology...
