Nutrient Agar

Nutrient Agar is a firm, gel-like substance used in laboratories to grow bacteria and other microorganisms. It combines nutrients essential for microbial life with a nutrient-rich base called agar, derived from seaweed. When sterilized and poured into petri dishes, it provides a supportive environment where microbes can multiply, forming visible colonies. This medium helps scientists study microorganisms, identify infections, and test antibiotics, making it a fundamental tool in microbiology labs.
