Synthesis and Characterization of Polyurethanes Containing D-lactose Residues in the Main Chain

α半乳糖苷酶因可水解人B型红细胞表面的α半乳糖残基，使B抗原结构变成O抗原结构，而成为B→O血型改造的工具酶。

α - Galactosidase could hydrolyze the α galactose residues on the surface of human blood type B erythrocyte , resulting in the conversion of the B antigen to O antigen .

五种缓冲剂对根瘤菌生长的酵母汁阿拉伯糖半乳糖培养基（YAG）低pH的缓冲作用进行了测定。

Five buffers were examined for their ability to buffer low pH during the growth of Rhizobium in yeast extract-Arabinose-galactose medium ( YAG ) .

草鱼结合胆汁酸盐像乳糖培养基中的牛胆盐一样，能够抑制革兰氏阳性菌的生长，而有利于革兰氏阴性菌如大肠杆菌（Bacilluscoli）的生长。

The combined salt was quite similar to cow bile salt cultured in lactose bile medium , which showed bacteriostasis to Gram positive bacteria , but not to Gram negative ones like Bacillus coli .
