Question

Why bacteria cannot survive in 70% concentration of alcohol?

Answer 1

hey mate here is your answer

alcohol kills bacteria mainly through 2 mechanisms: protein denaturation and dissolving the lipid membrane. Proteins, the machinery of the cell, must be dissolved in water in order to properly function. However, the lipids will freely dissolve in alcohol, causing a disruption of the bacterial membrane. so bacteria cannot survive in 70% concentration of alcohol
