solvents that avoid the use of classical organic solvents when performing enzymatic reactions. A noticeably change in regioselectivity was observed in the synthetic behaviour of Biolacta β-galactosidase using bio-solvents derived from dimethylamide and glycerol as co-solvents. Under these conditions, the enzyme changes its well known tendency to produce β-(1→4) to β-(1→6) disaccharides. An evaluation of
生物溶剂是很好的替代溶剂,在进行酶促反应时避免使用传统的有机溶剂。在使用衍生自二甲基酰胺和甘油的生物溶剂作为助溶剂的Biolactaβ-半乳糖苷酶的合成行为中,观察到了区域选择性的显着变化。在这些条件下,该酶改变了其众所周知的产生β-(1→4)至β-(1→6)二糖的趋势。为了优化反应条件以提高β-(1→6)产物的产率,对市售的Biolactaβ-半乳糖苷酶中的生物溶剂浓度和非蛋白质添加剂的作用进行了评估。
