Aquatic microbiology is the study of microorganisms that live in water environments, such as oceans, rivers, lakes, and wetlands. This field examines various types of microbes, including bacteria, viruses, fungi, and protozoa, and their roles in aquatic ecosystems. These microorganisms are essential for nutrient cycling, decomposition, and maintaining water quality. Researchers in aquatic microbiology also investigate how these microbes interact with their environment and other organisms. Understanding these interactions helps in addressing issues like water pollution, harmful algal blooms, and the impacts of climate change on aquatic ecosystems. This knowledge is crucial for managing and preserving water resources effectively.
