Modelling the survival of an Escherichia Coli in Soil : effect of pH and temperature

Survival of E.coli on soils determines its the availability for transport during rainfall events. In this study, the survival of E.coli in soil was examined under different pH in saturated condition. Results indicated that first order decay model fit well. Decay rate of E.coli increased when pH o...
