Microbial metabolism is a field of research that focuses on studying the metabolic processes of microorganisms, such as bacteria, fungi, and archaea. These microorganisms play a key role in various biochemical pathways, such as nutrient uptake, energy production, and waste product excretion. By studying microbial metabolism, researchers can gain insights into how microorganisms interact with their environments, adapt to changing conditions, and contribute to biogeochemical cycles. This research area is important for understanding microbial physiology, ecology, and potential applications in biotechnology and medicine.
