agar medium
Agar medium is a gel-like substance used in laboratories to grow microorganisms like bacteria and fungi. It is made from a natural compound derived from seaweed, called agar, which provides a solid surface for microbes to grow on. Scientists add nutrients to the agar to support the growth of specific organisms. When cooled, the agar hardens, creating a stable environment for studying or isolating microbes. It's an essential tool in microbiology for testing, research, and diagnosing infections.
