Science Buddies: "Ask an Expert"

Hi

I'm testing the effect of natural antibiotics on bacterial strains. Im culturing bacteria in agar from raw meat. I know there are many microorganisms that will form and its a bit dangerous, but I'll be careful. I'm wondering if raw chicken or beef is better to use? Raw meat bacteria are bacterial strains right? I can't order simple E coli k-12 strain because its too expensive and takes too long to mail.

Can i find a specific bacterial strain around my home that is usable?

Thank you very much

Please address my questions and the bacteria has to be a strain!

Hi
by opening the door of your Petri-dish you can see variety of fungi and bacteria in your culter.
you can use bacteria that lives in the soul to.

Hi,
I agree with the previous expert that opening your culture plate alone and exposing it to air will enable you to have microorganisms. I am assuming that you are interested in isolating a particular bacteria. From exposing your agar plate to the air, you will probably get a mixed culture. Thus, prior to your experiment, you can isolate one type of bacteria from your mixed culture. This link will hep you in performing this.
