Plate culture is a microbiological technique used to grow and isolate microorganisms on a solid medium, typically in a petri dish. The medium, often made of agar, provides nutrients that support the growth of bacteria, fungi, or other microbes. By spreading a sample evenly across the surface, researchers can observe colony formation and identify different species based on their characteristics. This method is essential in various fields, including medical diagnostics, food safety, and environmental monitoring. It allows scientists to study microbial behavior, test antibiotic resistance, and assess contamination levels in different samples. Plate culture is a fundamental tool in microbiology laboratories.
