Development period of the parasitoid pupa from the 5th instar larva fed on MSB was significantly longer. Length of cocoon of MSB treatment was significantly shorter than the control. However, no obvious differences were detected in the development periods of egg to larva, cocoon mass size, wasp emergence rate, sex ratio, longevity and forewing length of wasp between KMD1 and the control. 3. Amino acid content in the haemolymph of SSB after fed with transgenic rice Although there were no changes on the components of amino acids in the haemolymph of SSB after fed with two transgenic rice lines, there were some changes on relative contents of amino acids.

Furthermore,enzymatic production of cephalexin using free penicillin G acylase in aqueous system wasstudied. The parameters, including pH, temperature, concentration of 7-ADCA and molar ratiosof 7-ADCA to phenylglycine methyl ester, that affect the yield of cephalexin, wereevaluated. In section Ⅱ, the integration technique of bioseparation and biosynthesis was investigatedfirst time in the enzymatic production of cephalexin.

Therelationship of the amount of catalyst and the ee% of product was seen to be negative nonlin-ear. Catalyst 3 was used in the enantioselective addition of diethylzinc to aromatic aldehydesand gave good results. The configuration of products was determined by the configuration ofthe catalysts' chiral carbon linked with hydroxy group. Using β- amino alcohols bearing only one chiral center as catalysts for the enantiose-lective addition were studied. D-N, N-dialkyl-2-amino butanol gave poor catalytic effect be-cause of their structure. The configuration of the product is the same as the catalyst. Anotherkind of β- amino alcohols - phenylglycine derivatives and valine derivatives have chiralcenter on the carbon linked with amino group. Catalyzed by-phenylglycine derivatives 6,7, 9, 10, the reactions gave satisfied results. The optical yields exceeded 80%.
