| 摘 要： | 筛选高淀粉酶、蛋白酶活力枯草芽孢杆菌菌株,用于研制高效净水微生态制剂。通过对枯草芽孢杆菌液体发酵所产生的淀粉酶、蛋白酶活力的研究,从来源不同的10株枯草芽孢杆菌样品中筛选出2株蛋白酶及淀粉酶活力相对较优的菌株H001、H008,并对该2株菌株的形态、菌落形态、生理生化特征进行鉴定。基本确认所筛选到的菌株均属于芽孢杆菌属,可用于制备高效净水微生态制剂。

| Abstract: | To screen Bacillus subtilis strains with high activity of amylase and protease,for the purpose of producing high-efficient microbial ecological agent to purify water.Two strains with high activity of amylase and protease were selected from ten strains of Bacillus subtilis collected from different sources by detecting the activities of amylase and protease in fermented liquor.They were named as H001 and H008 and characterized according to morphology,colony morphology,and physiology.The two strains,H001 and H008 were primarily identified to be Bacillus spp.and they were suitable for producing high-efficient microbial ecological agents to purify water. |
