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 Left behind in Chicago
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.
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!
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.
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?
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 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?
I have a question. I have a task to grow salmonella at home so do you think it would be good if I took bacterias from raw chicken? Or do you have better idea?
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.
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.
@@crystelmeursecret It gives the bacteria something to eat. If you don't give them something to eat they will not grow. If have made that mistake in the past and wondered why nothing was growing.
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.
Has anybody thought about finding somebody who is infected with covid-19 or the Omicron virus and swabbing their mouth to see what grows in a petri dish? Or if they cough up phlegm test that in a petri dish
