Nosocomial infections caused death in 10% of surgeries. u Disinfectant: Applied to inanimate objects. The genetic factor is also called internal factor because the basis of plant expression (the gene) is located within the cell. Solutes and Water Acidity: Water is one of the most essential requirements for life. Factors Affecting Growth of Bacteria. Variations in any one or more of these factors may lead to the changes in the activity of the organisms which ultimately affect the soil fertility level. The factors that directly impact on bioremediation are energy sources (electron donors), electron acceptors, nutrients, pH, temperature, and inhibitory substrates or metabolites. Dampness is a big player in the growth of fungi.
