Microbial community research focuses on the study of the interactions and dynamics of various microorganisms within a particular environment. This can include bacteria, archaea, viruses, and fungi, among others. Researchers study how these microbial communities interact with each other, their environment, and larger organisms, and how these interactions can impact ecosystem function, human health, and various industrial processes. Techniques such as DNA sequencing, metagenomics, and bioinformatics are commonly used in microbial community research to analyze the diversity, composition, and function of these communities.
