Surfactant interference on lipase catalysed reactions in microemulsions.

J. Chem. Technol. Biotechnol. 54(3) , 277-82, (1992)

The hydrolysis of palm oil with lipase as a catalyst was carried out in two different microemulsion systems. One system was based on a nonionic surfactant, pentaethylene glycol monododecyl ether (C12E...
