It generally contains carbohydrates, nitrogen-containing substances, inorganic salts, vitamins and several other types of substances. Culture medium is not only a basic substance that provides cell nutrition and promotes cell proliferation, but also a survival environment for cell growth and reproduction. In bottle cap production, microbial testing is a key factor for verifying the eligibility of the produced bottle caps. However, before microbial testing, the microorganisms need to be cultivated first, and the precise subpackaging of culture medium can improve the accuracy of comparative testing.
