High Performance Protein-Coated Microcrystals of Rhizomucor miehei Lipase: Preparation and Application for Organic Synthesis.

The goal of obtaining enzyme forms with higher catalytic activity, greater stability, and improved reusability has been pursued for the last few decades. Various novel biocatalyst designs have been created, and protein-coated microcrystals (PCMCs) are one of them. PCMC is an enzyme immobilization method based on simultaneous precipitation of protein and carrier, forming micron-sized enzyme-coated crystals.

Synthesis of trimethylolpropane esters of oleic acid by Lipoprime 50T.

The ability of the commercial lipolytic enzyme Lipoprime 50T to catalyze the biotechnologically important synthesis of the biodegradable and environmentally acceptable trimethylolpropane (2-ethyl-2-(hydroxymethyl)-1,3-propanediol) ester of oleic acid was investigated. Simple and accurate thin-layer chromatography and computer analysis methods were used that enable one to follow changes of all reaction mixture components simultaneously. The processes of transesterification and esterification were compared.
