从湖南耒阳哲桥镇茶籽油榨油坊内采集土壤样品,分离筛选出能耐受茶皂素并产生碱性洗涤用蛋白酶的菌株.通过对筛选出的菌株进行初步形态鉴定、蛋白酶活力测定和污布去污效果比较,挑选出-株符合要求的菌株,命名为SJP-5.该菌株为革兰氏阳性产芽孢杆菌,无荚膜,能耐受茶皂素,产生碱性蛋白酶,其酶活力为150 U/mL,将其添加到清洗剂中并测定去污能力,试验表明:污布去污值Ri达到18,是平行菌株去污力的2倍.

A G＋ strain of Bacillus,named SJP-5,was isolated from the soil around an oil mill in Zheqiao Town,Leiyang,Hunan Province.It showed alkaline protease-producing capability with its enzyme activity being of 150 U/mL.The decontamination ability of a detergent added with this strain showed that the Ri was of 18,which was 2 times higher than t...
