Microbial consortia is a fundamental concept in microbial ecology and environmental microbiology, referring to natural or engineered communities comprising multiple microbial species that coexist and interact within a shared environment. This field investigates the structure, composition, interspecies interactions (including synergistic and antagonistic relationships), metabolic capabilities, and dynamic behavior of these complex systems, recognizing that emergent properties arise from collective activity. The study of microbial consortia is significant for understanding their critical roles in driving biogeochemical processes across diverse ecosystems and for harnessing their collective functions in biotechnological applications.
