Many types of projects are possible when you are able to count bacteria. For example‚ you could count the bacteria in drinking water‚ fresh milk‚ old milk that is slightly sour‚ buttermilk‚ yogurt‚ mud puddle‚ lemonade‚ and many other things. Or you may want to know how fast Chlorox kills bacteria. If you add some Chlorox to a culture and count the surviving bacteria at suitable intervals you can plot killing the killing curve and determine whether the killing is single hit or higher order.
