Factors Influencing Death of Microorganisms (MO): 
Mainly there are two major factors are involved in the killing of microorganisms. These are i) 
Growth environmental Factor and ii) Host body factors 
Growth environment factors: Microorganisms grow in a specific environment which enables 
them to complete their life cycle. Simple changes in growth conditions can result in killing of 
these organisms (Willey & Woolverton, 2012). Some points are discussed below. 
 Presence/absence of Oxygen: Some microorganisms are anaerobic and some 
aerobic.Presence of oxygen hampers with the electron transport system and kills 
anaerobic MOs. Likewise for aerobic bacteria absence of oxygen hamper electron 
transport chain and kills MOs. 
 Nutrient deficiency: If nutrients deplete from the growth environment MOs are unable 
utilize carbon source and cannot derive energy for its growth.
