The formation of the exoenzymes, neutral and alkaline proteinase as well as alpha-amylase of Bacillus subtilis, is characterized by the same time course. The exoenzyme formation starts in the exponential phase of growth by an excess of C and N sources. We assume that carbon metabolism of pyruvate is responsible for the exoenzyme formation during this growth phase. The proteinase formation at the transient and/or stationary phase of growth is related to amino acid limitation.
枯草芽孢杆菌的胞外酶、中性和碱性蛋白酶以及α-淀粉酶的形成具有相同的时间进程。胞外酶的形成在生长的指数期开始，此时碳源和氮源过剩。我们假设丙酮酸的碳代谢在这个生长阶段负责胞外酶的形成。生长的过渡和/或稳定期的蛋白酶形成与氨基酸限制有关。
