General description
Tomato Juice Broth is specifically designed for the cultivation of yeasts and other aciduric microorganisms. Lactobacilli, which grow poorly on standard culture media, require specialized nutrients for optimal growth. Mickle and Breed demonstrated the effectiveness of tomato juice in selectively inhibiting the growth of non-acidophilic bacteria. Dextrose serves as an additional carbon source, while yeast extract provides nitrogen, carbon, and essential B-complex vitamins. Potassium phosphates function as buffering agents, and the inclusion of several inorganic salts in low concentrations supplies essential ions that, along with yeast extract, support bacterial metabolism.
Application
用于酵母和其他嗜酸微生物的培养。
