Microbial ecology is the study of application to environmental science, ecology, and taxonomy of numerous microorganisms on Earth including soil, marine, wastewater, freshwater, air, food, animals, and the human gut. Ecological research, in particular, is the study of which microorganisms reside in a given environment, how they shape microbial communities, and how they influence the environment and humans. Furthermore, we isolated novel microoragnisms in a specialized habitat in order to conserve more diverse microbial resources on this planet, and taxonomic study (nomenclature/ identification/ classification) is being undertaken. We are now broadening the area of our research by investigating the ecology of archaea, fungi, and viruses which have gotten less attention in comparison to bacteria.
