弹性蛋白酶生产菌种的筛选及发酵条件的研究
Study on Filtration of the Strain Producing Elastase and Its Fermentation
【摘要】 通过科学的采样、初筛、复筛等合理的试验设计和大量研究工作,筛选到1株弹性蛋白酶高产菌株EL112,该菌株鉴定为Bacillus pseudofirmus。试验采用正交试验得出产弹性蛋白酶菌株的的最佳发酵条件:温度37℃,pH 7.5,转速150r/min。
【Abstract】 Through scientific designing and plentiful working,a bacillus had been filtrated,this strain was temporarily identified as Bacillus Pseudofirmus EL112 combination of the characteristics of morphology and physiology.And through science studying,I had found the best condition,the optimum temperature and pH this enzyme are respectively:37℃,pH 7.5 and rate 150r/min.
