| 摘 要： | 酪蛋白经胰酶水解后，可以被轮枝链霉菌SK-1所利用．采用pH-STAT法得到了DH=3、DH=6、DH=9、DH=12等4个水解度的酪蛋白水解物．当酪蛋白水解物作氮源时，其水解度(即肽相对分子质量的大小)对轮枝链霉菌SK-1产谷氨酰胺转胺酶酶影响很大，其中以DH=3的酪蛋白水解物效果最好，而且肽的浓度对轮枝链霉菌SK-1产谷胺酰胺转胺酶也有一定的影响，其中以4%的浓度最为合适．

| Abstract: | After being hydrolyzing,casein was utilized by Stretoverticillium SK-2.Casein hydrolyzated ( DH=3,DH=6,DH=9,DH=12 )were obtained with pancreatin.When the casein hydrolyzates were used as a nitrogen source,the dergree of hydrolysis(the molecular weight of casein peptide)had a significant influence on the production of transglutaminae by Stretoverticillium SK-2 and the optimum value was DH=3 ,The production of transglutaminase also depend on the concentration of casein peptide and,with 4% addition of DH=3 casein peptide,the production of transglutaminase reached 3.89 u/mL. |
