agar

I recently ordered some agar powder online because i thought it would be fun to try to make some vegan jello and what ever else i can come up with. I am having a hard time finding good recipes for agar jello. I know that agar comes out much firmer than gelatin buti was wondering if anyone knows...

i'am doing an experiment on "study of effect of antibiotics on microorganism" and in the experimental procedure it says autoclave PDA medium at 15 pound pressure. is it really necessary to autoclave?what if i do not autoclave?are there any alternatives? and i dont have autoclave machine aim...

I'm doing a science experiment and i have to present it in two days. I'm not sure how long the samples will last or what temperature to store them at. Keep in mind that the germs have already been grown. Also is there any way I can classify them by just looking at them? Thanks a lot! Thanks! any...

I am doing a science fair about bacteria and I have about 10, 3 and a half inch diameter petri dishes. How much water and agar should I mix together to fill all ten and allow bacteria to grow? Do I need to sterilize my tea pot when I boil it, and if I do...how would I do that with everyday house...

I add water and agar and pour in petri dish. Do mycelium ( or any cells ) will grow on it? Since PDA contain dextrose which contain nutrients, what about water agar?

For a project I designed, I grew bacteria from my finger on a petri dish with agar in it. Now, a bunch of various bacterial species are present in the dish. I would like to identify s. epidermis, if possible without a microscope. How could I do so? And if I did use a microscope, how could I...

Or can it be in a plastic container, like those that food are put in at the Walmart Deli? I am trying to grow bacteria in dif types of water.

For a research project, I need to get enough agar to fill up about 25-30 100x15 mm Petri dishes. I've never done anything with bacteria and stuff before, so I'm gonna need some help with this. The site that I'm purchasing the "agar powder" from comes in amounts of 10, 25, 50, 100, and 500. 1-...

First, how come not all species of bacteria and fungi can grow on NA and PDA, respectively? And second, why are NA and PDA plates incubated at 37 degrees Celsius and at room temperature, respectively? Thank you! :D

I'm supposed to answer how and why Agar and petri dishes are used in pathology. Thanks for any help :)

I would like to do plate counts from food samples (fruit) for staphylococcus areus. I have CLED medium, but I find that the fungus within the sample grows as a lawn, making it difficult to determine plate counts. Which medium would improve this?
