摘要
产碱菌麦芽四糖淀粉酶水解不同来源淀粉的产物组成有差异:G4占81.5％～98.8％,G_3占0％～9.6％,G_2占0％～5.9％。不同淀粉的水解速度在4170～9036mgGlch^-(1)·mg^(-1)之间。对可溶性淀粉的水解产物为6-型。麦芽四糖淀粉酶能被小麦、玉米及马铃薯的生淀粉吸附,其吸附率分别为60.2％、50.0％及52.2％,相对水解率分别为4.5％、2.7％及0％,水解生淀粉的主要产物为G_4。
When starch from different sources were treated with maltotetraose-forming amylase from Alcaligenes sp., their product compositions were different: G481.5%-98.8%, G30%- 9.6% and G20%- 5.9%. Their hydrolysis velocities were about 4170- 9036 mgGlc ·h-1 · mg-1. The product from soluble starch was α-maltotetraose. The amylase can be adsorbed on raw-starch from wheat, corn, and potato with adsorption rates of 60.2%, 50% and 52.2% and digestion rates of 4.5%, 2.7% and 0%, respectively. The main product from raw-starch was G4.
