If I wanted an antimicrobial agent that worked very quickly, I believe Cecropin would be best to use because it starts decreasing in 30-240 minutes. F15 showed highest activity, but it was slower than cecropin control culture. Cecropin is antibacterial peptide that is recovery bacterial cell membranes and response to the infection.

F15 proved to be a more potent antimicrobial agent than F12 because I saw the line graph of antimicrobial agent that F15 is decreasing in bacterial colony survival than F12. F15 is around 20% in 120 minutes, but F12 is around 54% in 120 minutes. After 240 minutes, F15 is decreasing to 15% and F12 is increasing to about 60%. But, F15 will not be on the pharmaceutical counter because it is a large protein and expensive. It is also purified form inclusion bodies after bacterial cultures.

I supported my hypothesis because I saw a data where cecropin and F15 can prevent the growth of bacterial colonies. It is interesting to see how they both decreasing in 30-240 minutes but increasing in 270 minutes. P.cinereus produces substances on the skin that may supply antimicrobial agent for protection. …show more content…
aureus because S.aureus can cause skin infections and it is Gram- positive bacteria with a single -layered that can be enter by antimicrobial agents. On the other hand, E.coli is a Gram- negative bacteria and it is unable to infiltrate the double -layered cell wall. It is also lives inside the body which antimicrobial agents can’t attack the bacteria. For example, if someone have diarrhea and used antimicrobial agent like F12 or F15 which it is not working. It is because these specific antimicrobial agents can act better on the skin like people who have skin infections like furuncles or
