Abstract:

用Haldane生长抑制动力学模型模拟了偏二甲肼(UDMH)高效降解菌群(FYD)的生长动力学过程,用Andrews非竞争性底物抑制动力学模型模拟了UDMH的降解动力学过程,拟合出动力学方程。通过拟合方程计算了比生长速率与比降解速率。结果表明,UDMH初始浓度为43.6980mg·L-1时,菌群有最大比生长速率,UDMH初始浓度为50.2261mg·L-1时,UDMH有最大比降解速率,理论值接近于实验值的50mg·L-1。菌群FYD降解UDMH的产率系数为0.229,反映了菌群FYD对UDMH的耐受性和利用情况。比生长速率与比降解速率的线性关系表明,在菌群FYD降解UDMH过程中存在物料平衡,细胞生长随UDMH浓度的变化存在合理性。
