Natural variability of the thermophilic culture of Bacillus diastaticus was studied, and the population of its cells was found to be genetically heterogeneous. The bulk (75.5%) of the cells had a high activity of amylase biosynthesis; 21.5% of the cells had a low activity; 2.94% of the cells had no activity. One inactive variant and two variants whose activity was higher that that of the parent culture with respect to amylase biosynthesis have been selected.
对嗜热淀粉酶芽孢杆菌的培养物的自然变异性进行了研究，发现其细胞群体在遗传上是异质的。大部分（75.5%）细胞具有高淀粉酶生物合成活性；21.5%的细胞活性较低；2.94%的细胞无活性。已筛选出一个无活性变体和两个在淀粉酶生物合成方面活性高于亲本培养物的变体。
