    The use of enantioselective hydrolysis for preparing chiral epichlorohydrins was investigated using recombinant Pichia pastoris with the enantioselective epoxide hydrolase of Rhodotorula glutinis. The rate of the recombinant epoxide hydrolase-catalyzed enantioselective hydrolysis of racemic epichlorohydrins was enhanced by the addition of 5% (v/v) Tween 20. Enantiopure (R)-epichlorohydrins with an enantiopurity of 100% ee and a yield of 26% were obtained within 5 min from 50 mM racemates
