Microbial analysis is the study of microorganisms, such as bacteria, fungi, and viruses, to understand their presence, behavior, and impact in various environments. This analysis is crucial in fields like healthcare, food safety, and environmental science, where identifying harmful microbes can prevent disease and contamination. Techniques used in microbial analysis include culturing, where samples are grown in controlled conditions, and molecular methods, such as PCR (polymerase chain reaction), which detect specific genetic material. These methods help researchers and professionals monitor microbial populations and assess their effects on human health and ecosystems.
