How to grow bacteria in a petri dish

My technique for adding and growing bacteria to petri dishes while minimizing the chance of contamination.

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

Thank you I can’t wait to grow my friends :>

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!

[Shandleyman]

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?

So here where I live where 90 fahrenheit is like ambient temperature at night and 100 fahrenheit is ambient temperature at day, is a regular shelf an incubator?

Thanks for this video! I want to do something like this for a kid’s camp but have limited time. Did you have growth within 1-2 days?

I'm just wondering, what kind of bacteria did you get when you dug a soil? is it bacillus subtilis?

i live in Guernsey channel islands where can i get these dishes from the ones with the red stuff in side

Hi, sir. I find your video really beginner-friendly. I just want to know if you add something on the agar?

[dylanoxgaming]

How much agar do I need for a petri dish do I need to fill it full of just enough to fill up blank spaces I keep failing so I need some advice and helps

Sir I want to grow a particular type of gut bacteria. But I am new to lab - experiment thing. Can u suggest me how to separate a particular bacteria and grow it in petri dish without interference of other bacteria.

[deepajames]

Do you need to have a BSL-1 level lab for this kind of experiment?

[noahirizarry]

I have an incubator but I don’t know what temperature it should be???

[infernalchaos]

I know I'm late to this video, but I have a question: in this video and your video on making the petri dishes, you kept turning the dishes upside down. Why do you do that?

Why do the dishes look like there is condensations in them?
