1.Waste beer yeast polypeptides were made from waste beer yeast by bromidic hydrolyzation, separation, purification and dryness etc.
以啤酒废酵母原料,经菠萝蛋白酶酶解、分离、纯、干燥等工序制得啤酒废酵母活性肽。
2.Method The target compound was synthesized from clarithromycin via hydrolyzation,acetylation,cyclic carbonatation,oxidation,decarbonatation,acylation,cyclic carbamatation and cyclization.
方法以克拉霉始原料,经水解、乙、碳酸、氧、脱碳酸、、氨基甲酸和合等反应合成目标合物。
3.degradation product from different component accelerated the aging, which could be exampled by the fact that HCl from degradation of PVC accelerated the hydrolyzation of cellulose and semicellulose.
