Will I be able to kill bacteria using electrical shock?
I wouldn't advise you experimenting with it, but yes,
bacteria will be killed by electricity when the shock
is high enough.
Strange as it sounds, scientists use electricity on
bacteria for a different purpose: a non-lethal shock
can help 'shoot' DNA into a bacterial cell. That is
called electroporation. We don't know exactly how it
works, but imagine the electrical current 'draws' DNA
into the bacterial cell. The bacteria then incorporate
this DNA into their own, with the desired effect for
scientific purpose. I know by experience that the
bacteria don't survive if you give them too high a
shock. So electrocutation is lethal for bacteria also.
