Nutrient Agar- Principle, Composition, Preparation, Results, Uses


Microorganisms are living organisms that are too small to be seen by the naked eye. They include bacteria, fungi, algae, protozoa, and viruses. Microorganisms are found everywhere in nature and play important roles in various biological processes. Some microorganisms are beneficial to humans, while others can cause diseases or spoilage.

To study the characteristics and functions of microorganisms, scientists need to grow them in the laboratory under controlled conditions. This requires the use of culture media, which are substances that provide the necessary nutrients and environmental factors for the growth and reproduction of microorganisms.

Culture media can be classified into different types based on their composition, consistency, selectivity, and differential properties. One of the most common and basic types of culture media is nutrient agar.
