What is another name for a liquid growth media, and what are the basic
components?
Your Answer:
Growth media in a liquid form is often referred to as nutrient broth. Its
composition consists primarily of essential ingredients such as a rich source of
sugars, amino acids, and vitamins. A nutrient broth provides the microbe with a
source of carbon/energy, which encourages its expansion.
