1. Which germicide was the most effective? Was the same germicide most effective for bacteria isolated from the different sources? What could explain this finding?Lab 7 Microbial Control BIO250L We ... did not find a difference in effectiveness. We could have had this happen because the bacteria did not grow or they were dead before the germicides were applied. 2. Which germicide was the least effective? Was the same germicide least effective for bacteria isolated from different sources? What could explain this finding? We did not find a difference in effectiveness. However, in theory, the Hibiclens would be least effective because it affects the cell wall of the gram positive much more than a gram negative cell wall. We could have had this happen because the bacteria did not grow or they were dead before the germicide was applied. 3. Were any bacteria from a specific source most resistant to the different germicides? If so, which source? Either they were all resistant to all germicides or there was nothing to be kill. 4. Did the dry filter paper serve as a positive or negative control? It served as a negative control because it did not contain any substance. 5. Look up the chemical formulas for bleach, isopropyl alcohol, and chlorhexidine gluconate (the active ingredient in Hibiclens). How does each chemical achieve its germicidal properties? [Show More]
