The Effectiveness of Antimicrobial Agents Bacteria: Clearasil and Proactive Veronica Hillgren 11/16/12 FRI AM Question/ Hypothesis The purpose of my experiment is to find and compare the efficiency of Proactive™ and Clearasil™ acne products on certain bacteria. For myself‚ Clearasil™ works better than Proactive™ does when exposed to my pores‚ which are infested with bacteria. However‚ Proactive™ is widely known and has a large amount

MICROBIOLOGY What is the purpose of general growth media‚ selective media‚ and differential media? Give examples of each. General Purpose Media General Purpose media is designed to grow most organisms and do not contain growth inhibitors. Standard Methods Agar and Blood Agar Bases are examples of general purpose media. Differential Media Differential media contain a component that allow an observable change when a specific chemical reaction takes place. Simmons Citrate Agar is an example

responsible for making the pillbug habitat‚ taking them in and out of the habitat for our experiment‚ setting up the experiment setups for testing‚ and timing the experiment. In my opinion‚ I contributed a lot in my group. I did a majority of the lab proposal‚ and a substantial amount in the lab report. I was always the one getting up to gather our materials and pillbugs from the bins and making sure that our experiment was going as smoothly as intended. From this project‚

Theodor Wilhelm Engelmann was a German microbiologist whose 1882 experiment measured the effects of different colors of light on photosynthetic activity and showed that the conversion of light energy to chemical energy took place in the chloroplast. In 1881‚ he observed the movement of bacteria towards the chloroplasts in a strand of “Spirogyra” algae. Engelmann hypothesized that the bacteria were moving in response to oxygen generated by the photo synthetically active chloroplasts in the algae.

Microbiology Unknown 5/7/2013 Microbiology Unknown #94 The purpose of this report was to identify an unknown bacterium by applying methods that were previously learned and conducted in microbiology lab class. It is possible to identify a mixed culture by running experiments on the unknown bacteria and taking what we already know and applying it to the results. It helps to slowly eliminate any bacteria that do not correspond with the results of certain tests. An unknown test tube labeled 94 was
