Studies were initiated to investigate the interactions between heterotrophic plate count bacteria and coliform organisms. We used spiked samples to show that heterotrophic plate count bacteria could reduce coliform densities by more than 3 logs within 8 days. Some heterotrophic plate count bacteria were able to cause injury to the coliform population. A significant correlation (r = 0.66; P less than 0.05) was observed between the initial level of heterotrophic plate count bacteria and the rate of coliform decline. Competition for limiting organic carbon was hypothesized to be responsible for the observed effects.
开展了多项研究以调查异养平板计数细菌与大肠菌群之间的相互作用。我们使用加标样本表明,异养平板计数细菌能够在8天内使大肠菌群密度降低超过3个对数级。一些异养平板计数细菌能够对大肠菌群造成损害。观察到异养平板计数细菌的初始水平与大肠菌群下降速率之间存在显著相关性(r = 0.66;P小于0.05)。据推测,对有限有机碳的竞争是造成观察到的这些影响的原因。
