Hello, I am currently trying to grow a bacteria lawn or a spread plate with Bacilllus subtilis. I do not have nutrient broth powder as a liquid medium. So can I use peptone water as a substitute to culture B. subtilis before I spread?

Hello, I am a high school IB student. For my research paper, I will be testing the effects of different hand sanitizers on Bacillus Subtilis. Here is my problem: I only have a plate culture of the specific B.Subtilis bacteria and I do not have the powder for a liquid nutrient broth. Therefore, how do I create many plates with a lawn culture of b subtilis?

My name is Ben and I am a high school student. I am currently conducting a research on the efficacy of 3 different types of hand sanitisers on bacteria (Bacillus subtilis). I would like to ask this question: Is it safe to culture and grow samples of bacteria directly from our hands? This is one of the issues that has deterred me from continuing my research as my teacher is not sure whether it is safe and I was hoping that you would be able to clarify things a bit! Thank you Best Regards, Ben
