Classification of culture medium
Classification of culture medium by components
Due to the wide variety of microorganisms, the demands for nutrients are different, and the required culture media are complex and diverse. According to incomplete statistics, there are about 1700 kinds of commonly used culture media at present. Moreover, with the development of biological science, the types of culture media are constantly increasing. At present, the classification method of culture medium is not unified, and it is usually distinguished according to the composition, physical state and use of culture medium.
