摘　　要：利用紫外线诱变出发菌株S1并筛选出高产纤维素酶的菌株NS1。结果表明:诱变菌株NS1在28℃培养48h,酶活达15.04U/mL,分泌的纤维素酶活力比出发菌株S1提高1.51倍。Ultraviolet ray(UV)was used to induce mutation on S1 and a new Bacillus subtilis NS1 with high yield of cellulase has been selected.The cellulase yield of NS1 was 1.51 times than that of S1 and the yield of cellulase reached the highest when they were cultivated 48 hours.NS1 from induced mutation had better capacity of producing cellulase,which provided a theoretic base for natural cellulose decomposition.
