I'm very new to experimental biology and don't know much about it. So, i was looking to grow some bacteria in petri dishes and looked up how to do it. Unfortunately, I'm finding it difficult to get my hands on the 'agar-agar' required to make the culture medium. So, is it possible to use any other alternative which would give the same results? Like for example regular gelatin?
My school lab teachers have also shown little to no interest in helping me with my project, so I'm on my own here. Any tips would be greatly appreciated!
To better assess your issue, I need to know what type of bacteria you plan to grow. I have never tried growing bacteria on normal homemade gelatin, you should definitely try to go with a method that you know works (i.e. normal agar plates). You can actually purchase them on amazon for about $15. If you would like to use a safer route to purchase them, go to fisher scientific. Most universities actually purchase their plates on that website (https://www.fishersci.com/shop/products/prepared-culture-media-plates-nutrient-agar-10-pk/s716931a).
