Abstract

alpha-Chymotrypsin has been immobolized on porous silica beads. The activity, optimum temperature and pH of the immobilized chymotrypsin aswell as its Michaelis constant have also been determined. Its stabilities to heat, acid, base, methanol and urea are increased remarkably. It has been applied to resolving DL-phenylalanine continuously more than two months with good performance. L-Phenylalanine is obtained in a yield of 90%, and its optical purity reaches as high as 96%.
