There are so many soaps available in markets today, that advertise as the "best anti-bacterial soap." I figured that as I was studying bacteria in class, I should test the claims of the soap-producing companies, and perform an experiment to test which soap was actually the most disinfectant.

While antibiotics are very powerful in the cure of many bacterial diseases, some bacteria have developed ways to resist antibiotics. The extensive use of antibiotics (unfortunately including the over-prescription and misuse of these medications) has resulted in the evolution of bacteria that are not be killed by antibiotics and these bacteria once again threaten health and life. Diseases that were

Biologists do not yet know why these bacteria produce light. One idea is that producing light gives these bacteria an advantage for survival. By glowing, they attract fish, which they then use as a host organism — the bacteria are able to live in the fish's body. These fish, which are attracted to the bacteria's light, pick up the bacteria and prevent them from settling on the bottom of the ocean

The purpose of this experiment is to determine the relationship between the concentration of disinfectant and its effectiveness in destroying bacteria.

This project examines how effective dog saliva is against bacteria.

The objective is to determine which acne medications are the most effective in inhibiting the growth of Propionibacterium acnes, over-the-counter or prescription.

With the result that application of an electric field apparently halted bacterial cell division and led to filamentous growth, we sought to understand better the cause of this phenomenon. (Recall that filamentous growth occurs when cell division—but not cell growth—is inhibited.)

I tested my hypothesis by taking samples of bacteria from the feet of a chicken, a human, and a rabbit, placing them in augers, and recording their growth over three days. I used a culture mix, water, a stove, a pot, nine petri dishes, graph paper, and samples of bacteria in my project. The full procedure went like this. I first mixed the water and the culture mix, then boiled it, and added some t

My objective was to see what the affect was of ultra-violet light on bacteria. I hoped that the bacteria would get killed, and wanted to see a decrease in bacteria colonies.
