Question:
Will I be able to kill bacteria using electrical shock?



Replies:
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.
