The Microbial Resource Research Infrastructure (MIRRI) is a distributed Research Infrastructure for the preservation, systematic investigation, provision and valorisation of microbial resources and biodiversity. MIRRI aims to serve the Bioscience and the Bioindustry user communities by facilitating their access to a broad range of high-quality microbial bioresourses, microorganisms, their derivatives, associated data and services, with a special focus on the interconnection domains of Health & Food, Agro-Food, and Environment & Energy. The MIRRI partners strive to alleviate the fragmentation of bioresource holdings and expertise, to deliver fit-for-purpose microbial material, to add value to microbial diversity, and to discover and preserve the yet unknown or uncultivated microorganisms.

MIRRI was included in the ESFRI Roadmap 2010 and was acknowledged as ESFRI Landmark in 2021 when it successfully submitted the European Research Infrastructure Consortium (ERIC) Step2 application. MIRRI brings together more than fifty microbial domain Biological Resource Centres (mBRCs), culture collections and research institutes from 11 European countries. The statutory seat of MIRRI ERIC will be located in Portugal while the Collaborative Working Environment Hub will be operated from Spain in cooperation with LifeWatch ERIC Common Facility situated in Spain. The materials and services will be provided by partners in MIRRI member countries, coordinated by their national nodes. Users will be able to easily search MIRRI services and make requests on the MIRRI access portal.
