Today was all about safety in the lab. We learned the proper
way to enter and exist the lab to avoid carrying anything harmful into or out
of it. We also practiced the aseptic technique for transferring cultures from
one tube to another.
That made us excited to get to do it for real. The other thing the class did was we split
into two groups and each made a different type of culture collection tool. Our
group made the agar plates (Petri dishes) and the other group made the agar
broth tubes. The agar mixture we made was a liquid when it was warm, but once
it cooled it became a solid. Before placing it in the Petri dishes to cool,
both things had to be made sterile. We put them into an autoclave. The autoclave
heated it to a very high temperature for 15 minutes. No bacteria can survive
that type of heat. When the liquids are removed they are completely sterile and
ready to use. So now that we know safety in lab, the fun can officially begin!
