Classical media and buffers are fundamental components in microbiology laboratories, serving various purposes in the cultivation and study of microorganisms. classical media provide the necessary nutrients for the growth of microorganisms and can be selective or differential, allowing for the identification of specific microbial characteristics. Buffers, on the other hand, help maintain a stable pH in experimental settings, which is crucial for the proper functioning of enzymes and other biological processes. Both classical media and buffers are indispensable in microbiological research and diagnostics.
