Category Culture Media

culture media is food to grow microorganisms in the laboratory. Microbes require nutrient and suitable environment to grow and survive. They need nutrients like carbon source, nitrogen source, salts, vitamins and minerals. There is variation in nutritional’s needs of every microorganism. Therefore, it is impossible to grow all microbes with single type of culture media. In microbiology various types of culture media are available to grow bacteria.
