    I bet you never expected growing things on agar would have such a broad range of interested parties. Thanks for your content.

    Hello I found your video very helpful but I have just a few questions. The first one is, is agar in the Petri dishes harmful and what are the disks you used to add in the cleaning liquids. Thank you!

    I love your methods!
    The UV light thing got me thinking.
    Could I put an Agar petri dish in a UVC chamber (I have one for erasable microchips) with the lid on to kill anything that's in the dish before using it?
    It might be overkill but I too do not have a big budget and would like to do my best to act clean.

    Thanks.
    I want to check bacteria germs in some kitchens, bathrooms in my Co-OP building and a neighborhood bar across the street.
    I don't have an "incubator" but you said it was more about a warm ~ 90 F dry place. That should be something I could do, how about an oven?
    Another question, can I sterilize the Q Tip with just bowling water, then putting the Q tip to dry then in to a plastic bag?
    Thanks Jaye

    I have a question. Instead of using a cleaner for your examples, is it possible to use an antibiotic or some kind of solution instead to see if bacteria grows near it?

      I have used penicillin and other types of antibiotic disks and got great results with that.

      @brightbiology9632  2 года назад

      I would definitely think so. You just should keep them in a container so they don't dry out.

    • @brightbiology9632
      @brightbiology9632  2 года назад +2

      If it is nutrient agar, then no, if it is just pure agar, then I add a soup bouillon cube. I'm going to experiment with better smelling things besides a bouillon cube though.

      @brightbiology9632  2 года назад

      If there is a small number of colonies I just count them, or if there are lots of little ones, I would put a grid behind the dish and count a couple squares and then and extrapolate.

      Most people will either put them into an autoclave/pressure cooker which can be really smelly or they will put them in a bag that is labeled as biohazard and disposed of properly.
