苏云金芽孢杆菌防治法对大曲质量的影响

Study on the Effects of Bacillus thuringiensis Prevention Method on Daqu Quality

对苏云金杆菌防治大曲害虫过程的杀虫效果与大曲质量影响进行了研究。结果表明,利用苏云金杆菌毒杀大曲害虫,大曲的糖化力、液化力、发酵力与试验前相比略有下降,分别为7.8%,11.6%,8.0%;而对照组与试验前相比,3个指标明显下降了31.2%,29.2%,40.4%;对微生物的影响甚微。

Bacillus thuringiensis was used to prevent Daqu pest and its prevenntion effects and its influence on Daqu quali- ty were studied. The results indicated that the saccharifying power, the liquefying power and the fermenting power of Daqu decrease by 7.8 %, 11.6 % and 8.0 % respectively after the use of bacillus thuringiensis.The three indexes of contrast group decreased by 31.2 %, 29.2 % and 40.4 % compared with that before the test, which had little effects on microbes.
