How does bleach kill bacteria?

Answer 1

According to the journal articles (see links below) cited, hypochlorous acid - the active ingredient in bleach - kills bacteria by denaturing their proteins. The process is apparently very similar to the denaturing effect of heat on proteins - it causes them to change shape and clump together, leading to the death of the bacteria.

Answer 2

Beach is a generic term for a chemical or chemical compound that removes colors and coloration stains. Usually, this is an effect of oxidation, effected either by chlorine compounds (such as sodium hypochlorite (NaClO)) or oxygen compounds (such as hydrogen peroxide (H2O2)).

It's the chlorine compounds in chlorine bleach that make it useful as an anti-bacterial, anti-fungal, disinfectant, or sterilization tool.

Depending on the concentrations used, chlorine bleach can kill most all microorganisms, and, for that matter, macro-organisms (like pets or people) too.

There are some bleach-resistant bacteria, just as there are bacteria that are resistant to most all forms of disinfectant, and more of them are evolving all the time. The more use we make of anti-bacterial agents, the more resistant strains will evolve.

Chlorine bleach works chemically rather than biologically. Rather than bonding to specific proteins in the target, the chlorine in bleach works by directly reacting with the cell wall causing it to burst, usually before there is a chance to alter it to not react with chlorine. This is one reason bleach (especially at high concentrations) is such an effective disinfectant (and also why it is so indiscriminate); it is much more difficult to develop or improve a chemicalresistance.

Answer 3

A leading brand of disinfecting wipes is Germ-X. The Germ-X brand of disinfecting wipes kills about 99.99% of germs found in our world. These wipes can be found at mass retailers such as Walmart, Target, or KMart.

Answer 4

Bleach kills bacteria by disrupting their cell membranes and causing them to break down. It also interferes with the bacteria's ability to function and reproduce by disrupting their protein and enzyme molecules. This leads to the bacteria's death and helps to disinfect surfaces.

Answer 5

Bleach or sodium hypochlorite is a potent oxidant.
