Bismuth sulfite agar

Bismuth sulfite agar is a type of lab plate used to help check for certain types of bacteria in the environment. The agar is a jelly-like substance that has special substances like bismuth sulfite, which helps spot and grow the bacteria in the sample you put on the plate. To use the agar, you take a sample from something you want to test, like food or soil. Then, you put it on the bismuth sulfite agar plate and wait. The bacteria on the sample will grow on the plate, and you can then look at the plate to find out what kind of bacteria there are.
