Community-level flux balance analysis

Definition

Community-level flux balance analysis is a computational method used to model and analyze the metabolic activities of microbial communities as a whole, rather than focusing on individual species. This approach allows researchers to understand how different organisms within a community interact and share resources, providing insights into the overall functionality and efficiency of microbial ecosystems.
