Aldehydes achieve sterilisation by which mechanism?

Explanation:
Aldehydes sterilize primarily by alkylating and cross-linking cellular proteins, which irreversibly inactivates essential enzymes and structural proteins vital for the microbe’s survival. This protein inactivation disrupts metabolism, enzyme activity, and membrane integrity indirectly, leading to cell death. They don’t act mainly by disrupting membranes, oxidizing sugars, or solely damaging DNA; while DNA can be affected as a consequence of protein cross-linking, the main antimicrobial action comes from protein modification.
