Water and Dampness Warmth, moisture, pH levels and oxygen levels are the four big physical and chemical factors affecting microbial growth. The following points highlight the six main physical factors affecting the growth of microorganisms. Environmental factors such as weather influence the transport and dissemination of microbial hazards via rainfall and runoff and their survival and/or growth through according to temperature or humidity conditions [ 13 ]. The factors that directly impact on bioremediation are energy sources (electron donors), electron acceptors, nutrients, pH, temperature, and inhibitory substrates or metabolites.
