摘要
根霉2(Rhizpussp2)是从土壤中分离筛选得到的野生型生淀粉分解酶高产菌株。通过对该菌所产生的生淀粉分解酶的性质研究得知,该酶对不同淀粉原料的分解能力不同;该酶的最佳作用pH范围是3.0~5.2,最佳作用温度范围是38~42℃,50℃以下酶活稳定,该酶不受终产物葡萄糖的抑制。
Rhizopus sp 2 isoated from soil was a high-yiels producer of raw starch decomposing enzyme (glucoamylase) .The study of the glucoamlase produced by Rhizopus sP 2# indicated that the decomposing ability of this glucoamylase to different starch and the absorption rate were different. The optimal pH and temperature range for the enzyme reaction were 3. 0~5. 2 38~42℃ respectively. The enzyme was stable at temperature under 50℃. The enzyme reaction was not inhibited by glucose.
