How does embalming influence microbial viability?

Embalming reduces microbial viability by fixing tissues with chemical agents that inactivate many microbes and slow decomposition. Fixatives like formaldehyde cross-link proteins and nucleic acids, denaturing enzymes and damaging cell structures, which limits microbial growth and activity. The process also distributes preservative solutions through the vascular system, lowering microbial load in accessible tissues. Yet it is not a sterilization method; some hardy organisms, such as spore-forming bacteria, can survive in protected niches or in areas not fully penetrated by the solution. So the effect is a substantial reduction in viability, not complete elimination.
