We are a group of high school students from Manila who is performing an investigatory project on a topic that we chose which, at first glance, seemed simple, but turned out a bit complicated. We're trying to test the effectiveness of SODIS of solar water disinfection in killing bacteria.
I previously asked a question here at Stack Exchange and we consulted our teacher about the answer we received. According to her, at our level, it is best to use culture media. Our testing will be qualitative. We won't be identifying the specific type of bacteria. Rather, we will observe culture media if anything grows in there.
She gave us an assignment to research about what medium to use. Due to inexperience and lack of knowledge on what we find on the internet, we resorted to ask here again.
For bacteria commonly found in tap water, what culture medium do we use? We found mentions of Legionella, Salmonella, E. coli, and Anabaena sp. in our research.
In this article, we found different types of culture media. TSA captured our attention because it is a "general type." Nonetheless, we're not that sure about what "general" means if it means it can be used for the bacteria I mentioned above. There's also EMB that appears to be used in two of the bacteria we mentioned.
Edit: It appears that not all culture media is good for student use. According to this article, only LB Agar, Nutrient Agar, and Tryptic Soy Agar can be used by students. Among these three, is there something I can use?
