【Abstract】 The conventional lysozyme production gives several problems and low yields. On the contrary, lysozyme is easily prepared by using L-d absorbent which is based on the principle of combaining ion-exchange with absorbtion. Since the main steps -solting out, dialysis and freeze drying-may be cut down, the working process is simplified and the cycle time is shortened from 7 to 2-3 days. A high yield (-50000u/g egg white) and high aclivities (15,000-20,000u/mg) can be obtained by using the new route at Iow cost (30000u/g and 9000u/mg by conventional way) . In addition, it provides means for multiple utilization of the egg products.更多还原
