Lipase

An enzymatic reaction in ionic liquids was studied with a special attention to the water content. Water, as a byproduct of the esterification by lipase should be removed to enhance the synthesis. Pervaporation was studied for water removal in integrated system.

A lipase-immobilized biphasic membrane reactor was applied for the optical resolution of racemic 2-hydroxy octanoic acid. Lipase from Candida rugosa or Pseudomonas cepacia was used as a biocatalyst, and three kinds of capillary membranes were employed as immobilization supports. The (S)-isomer of ra

Two concepts of the localisation of hydrolytic enzymes with the use of a membrane phase contactor are presented in the paper. Because of the participation of water molecules in the process, the enzyme should be immobilized so that it could be in contact with the aqueous phase. Thus, enzyme immobilis
