Culturing, a term for growing microorganisms in the laboratory, is a basic yet indispensable method in microbiology research. Microorganisms are often cultured in a liquid medium that provides essential nutrients, and this process is both simple and highly effective. In addition to nutrients, oxygen availability is also critical for the growth of aerobic microorganisms. However, oxygen does not dissolve easily in the liquid medium. As a result, the medium needs to be forcibly aerated, usually by shaking.
