Welcome
The Organizing Committee cordially invites you to participate in the 10th Biennial Meeting on Microbial Carbohydrates, organized by the Hirszfeld Institute of Immunology and Experimental Therapy in Wrocław, which will be held on location at Krzyżowa Palace, Poland.
Special Issue of Carbohydrate Polymers
The Organizers are proud to announce that a Special Issue of Carbohydrate Polymers (latest IF 10.7 from JCR) will be dedicated to 10th BMMC 2025. Participants are welcome to contribute to this Special Issue, both Regular and Review articles will be accepted.
The Biennial Meeting on Microbial Carbohydrates in a nutshell
The 10th Biennial Meeting on Microbial Carbohydrates (BMMC) conference continues the long-standing tradition of regular meetings of the international scientific community interested in the microbial glycans in terms of chemical analysis of their structures, synthesis and biosynthesis, carbohydrate biochemistry, intermolecular interactions and biological activity.
The lectures and communications presented cover a wide range of microorganisms, including bacteria, viruses, parasites, archaeons and microalgae. Major topics dealt with include important healthcare issues such as infectious diseases and vaccination. The overall message is complemented by reports on the latest analytical methods, bioinformatics and databases that provide indispensable support for glycan research. The conference dates back to 1988. It has evolved from the early Baltic Meeting, and its reach has since expanded geographically far beyond the first three countries involved.
The Scientific Committee comprises distinguished researchers in the glycobiology community, the research teams’ leaders from Austria, Germany, Finland, Ireland, Italy, and Poland, representing the wide gamut of subjects in the carbohydrate chemistry and glycobiology. The conference aims to integrate research teams and to encourage the participation of PhD students and researchers from all over the world. Frequently, the conference engagement and presentations have resulted in successful collaborations, post-doctoral positions or joint projects and publications. After 20 years, the Ludwik Hirszfeld Institute of Immunology and Experimental Therapy in Wrocław has the privilege to be once again the organizer of the conference.

BMMC 2025 Venue and Attractions
The International Conference Center
& Krzyżowa Village
The 10th BMMC will be held in Krzyżowa, a small village in the region of Lower Silesia, about 60 km to the south-west of Wrocław, near the town of Świdnica.
The conference venue follows the long-standing tradition of integrating chemists, glycobiologists and microbiologists away from the big cities. It combines a conference center with a hotel base. The horizon is overlooked by the massif of the Sowie Mountains and the mysterious Ślęża Mountain, as well as by farmland around Wrocław and the surrounding area.
Social Activities
Wednesday, Sep 10: An evening meal will be served during an outdoor barbecue & bonfires.
Thursday, Sep 11: An evening Reception & Gala dinner in the Restaurant ‘U Hrabiego’ followed by a dance party.
All participants are invited at no additional cost.
The City of Wrocław
We highly recommend a city tour of the old town and the riverside of Wrocław.
Meet the team
Hirszfeld Institute of Immunology & Experimental Therapy
Hirszfeld Institute of Immunology and Experimental Therapy of the Polish Academy of Sciences in Wrocław is a leading research center in immunology, experimental oncology, microbiology, immunochemistry, glycobiology and medicine – with a focus on diseases of civilization, new drugs and vaccines, as well as transplantology & regenerative medicine. The Hirszfeld Institute comprises 23 laboratories that cooperate closely with other integral entities: Medical Center which includes the Phage Therapy Center and the Laboratory of Tissue Immunology, the Polish Collection of Microorganisms, the Eukaryotic Cell Line Collection, and the NeoLek, the Innovative Medical Technologies Laboratory. The research activities are supported by the local Animal Facility, and Core Laboratories (i.a. NMR spectroscopy, mass spectroscopy, cytometry, TEM/SEM microscopy). In 2023 the Hirszfeld Institute was classified at the top category in medicine (A+) and in biology (A) among Polish academic institutions. It was ranked 5th among all Polish research institutes and universities according to the Scimago Institutions Rankings.
The institute was established in 1952 by the Polish Academy of Sciences. Professor Ludwik Hirszfeld, a famous Polish immunologist and microbiologist, was the founding father and the first director.
