Okay, I am doing an experiment for a class. I am going to see if bleach or garlic juices kill bacteria better. I have the bacteria grown in Petri Dishes and everything seems to be going well. The only thing is, I started late since I messed up and I am running out of time.
Anyways, I don't know how I will know if the bacteria dies. Will it turn white, dissolve, or something else? Please tell me how I will know it is dead! Thanks so much in advanced!

Are you hoping for a miracle?
As the ice caps melt away.
Well how do you know that you actually have bacteria? Or that its actually alive?
Need more info please.
No use hoping for a miracle.
There's a price we'll have to pay.

Hmmm... There has to be books about this stuff. How did you know how to grow the bacteria?
If you do know there is bacteria in the dishes, use medical grade alchahol. That's proven to kill bacteria. Do a few drops to a spare petri dish if you have one and you'll know what they look like dead

They should dissolve or at the least shrink.

well, when they are alive they keep growing, don't they? so if they die they will stop growing. I'm not sure if there is any color change or anything though.
