IT DOESN'T: The only real use for peroxide is to help wash stuff out of a dirty wound. It doesn't kill bacteria even as much as a topical antibiotic. It will even damage healing tissue. Does it bubble when 'germs' are present? No, it just bubbles peroxide is water with an extra oxygen atom. This is weakly attached and wants to come off hence the bubbling. Bacteria? No it will bubble on clean glass.

Yes: Not a big fan of peroxide for wounds- actually impairs healing. Can occasionally be useful to clean out dried blood etc, but personally don't use it.
