The patterns of microbial mineralization of 0.3 to 30 ng of glucose, benzoate, and phenol per ml of sewage collected in late fall and winter were analyzed with the integrated Monod equation and a model in which growth of active organisms occurs at the expense of organic compounds other than the test substrate. Either model could be closely fit by nonlinear regression to the data from individual tests with one concentration of substrate added to one dilution of sewage. However, neither model accounted satisfactorily for differences in patterns of mineralization resulting from differences in substrate concentration and cell density between different tests. It is suggested that both the added substrates and other organics present in sewage contributed to the growth of the active organisms. The mineralization of glucose in sewage collected in summer was better described by a two-compartment model than by any other model tested.
采用整合的莫诺方程和一个模型，分析了在深秋和冬季采集的每毫升污水中含有0.3至30纳克葡萄糖、苯甲酸盐和苯酚时的微生物矿化模式，该模型中活性生物体的生长以除测试底物之外的有机化合物为代价。对于向一种污水稀释液中添加一种底物浓度的单个测试数据，这两种模型中的任何一种都可以通过非线性回归很好地拟合。然而，对于不同测试之间因底物浓度和细胞密度差异而导致的矿化模式差异，这两种模型都不能令人满意地解释。研究表明，污水中添加的底物和其他有机物都促进了活性生物体的生长。与所测试的任何其他模型相比，两室模型能更好地描述夏季采集的污水中葡萄糖的矿化情况。
