Best Answer: Ethyl alcohol, at the concentrations used in most antibacterial preparations, kills bacteria by disrupting membranes and by denaturing proteins. Ethylalcohol is miscible in water (that is, completely soluble). But ethyl alcohol can also dissolve in the membranes of cells.
Is a group of chemical compounds whose molecules contain a hydroxyl group bonded to a carbon atom. Made by the fermentation of sugars. Also, if there is an equal percentage of alcohol used on the Staphylococcus Epidermidis and Escherichia Coli, then the Staphylococcus Epidermidis will be greater affected by the alcohol. Hypothesis. If there is a higher percentage of alcohol content, the alcohol will greater inhibit the growth of the bacteria. Also, if there is an equal percentage of alcohol used on the Staphylococcus Epidermidis and Escherichia Coli, then the Staphylococcus Epidermidis will be greater affected by the alcohol.
