MicrobiomeNet (https://microbiomenet.com) is a web-based platform developed to provide functional insights into microbiome signatures using genome-scale metabolic models (GEMs). It currently hosts 12,400 GEMs and around 6 million microbial signatures. Users can start by searching microbes, metabolites, genes, or enzymes, and perform common tasks such as to characterize the metabolic capacity for a given microbe, to explore known microbial associations, as well as to understand potential metabolic interactions. This book chapter provides practical, step-by-step instructions for navigating MicrobiomeNet to obtain functional insights into individual microbes or microbial association networks. © 2026 The Author(s).
