The MIFFi with an extremely good program (https://miffi.org/), and the FMT will be there too!
Watch out for Ker Sin Ng presenting 'A Novel Microbial Consortium for the Production of Antimicrobial Fermentates Containing Caproate'
and posters by
Mensure Elvan Gezer: 'Optimized Antifungal Propionate Production by Loigolactobacillus coryniformis for Food Preservation' P28
and Rebekka Herdis Lüf: 'Beyond Lactate: Exploring Microbial Cross-Feeding to Improve Antimicrobial Activities' P58
We celebrated the first PhD student of the FMT group:
Ker Sin Ng succesfully graduate on March 3rd with her work on 'Old Natural Compounds That Are Underexploited--Antimicrobial Mode of Action of Short-chain Carboxylic Acids and Their Potential as Biopreservatives'.
Congratulations Ker Sin!
In a new publication in Microbiology Spectrum, we show that human fecal microbiota is highly competitive for the dairy sugar lactose. Lactose was used through microbial cross-feeding, or (even more interesting) directly by butyrate producers. We had previously observed that Anaerobutyricum hallii can use lactose, but only now have we been able to place it in an ecological context. Competition of the starter culture was much lower, even when added together with lactose.

journals.asm.org/doi/10.1128/spectrum.02193-24Work initiated by Qing Li and Freja Foget Andersen with a lot of contribution from Angeliki Marietou, Carsten Scavenius, Jiří Hošek and Jianbo Zhang.All made possible with funding from Mælkeafgiftsfonden and the Hartmann Foundation.
Functional Microbe Technology started the year with a roam through Aarhus together with our lab buddies Microbial Synthetic Biology (MSB) and Multiscale Microbial Engineering.(MME). We set the foundation for the FMT/MSB/MMB Philosophy and celebrated with a meat-lovers lunch. Great to work with such a wonderful group of people!
With a timely and important editorial on the potential of microbial technology on the initiative of Kenneth Timmis. Take some time and give it a read - it is extensive! Happy to have contributed a tiny bit.

I am very happy and proud to announce that I have been recently promoted to Full Professor at Aarhus University.
Despite the many challenges that work at a university entails, there is no other job I would rather have. It is a privilege to provide research-based education to students while running an independent research group, whose curiosity, motivation and unforeseen outcomes make every week unpredictable and never boring.
A big shout out to all the current and past students at University of Alberta, University of Vienna, ETH Zurich, CZU Prague and Aarhus University, you are a big part of this! And it is a pleasure to see thrive still at, or after university.
Heads up to the many colleagues and collaborators past and present and the many coffees that were drunk. Every move was done at a different career stage and asked for an introduction to a new place and university, education style and funding landscape.
And finally, this would all have not been possible without a partner, who agreed to move along even though there was hardly any certainty on where the journey would bring us, and who manages life at home. We are glad that we ended up in Denmark and have been making our base here.
I am looking forward to further consolidating our research on the interface of food and gut biotechnology at Aarhus University that addresses many current societal issues related to sustainable and safe food and gut health.
…and to contribute to the development of the (young) Department of Biological and Chemical Engineering and the Section of Industrial Biotechnology. Look out for us, there will be more to come!
There will be a small celebration, date will be linked in the comments once set.
And the good news came during vacation:
Excellenet news, new paper from Ker Sin on her PhD journey to investigate food relevant short chain carboxylic acids in more detail. Have a look at: https://journals.asm.org/doi/full/10.1128/spectrum.01658-24?af=R
Watch out, there is more to come!
Funding from the Novo Nordisk Foundation for the project BIOFUNC.
This one was a long time in the making - but it was really a matter of the heart. Congratulations and thanks to Qing Li, who kept persistent, and to all the patient collaborators. Funding from the Aarhus Universitet Forskningsfonden and from EMBO for the stay of Qing at ETH Zürich. Glad that fundamental research is still possible!

It starts to look real, the labs are getting renovated and FMT with its sister groups MME (Alvaro Lara) and MSB (Marta Irla) are looking forward to moving later this autumn.
It becomes a tradition, in August, BCE retreats to the beautiful Mols Bjerge for two sunny days.. FMT sent 9/170 participants
Finally InfantAD gains momentum! Possible due to funding by the LeoFoundation.
Happy to be granted resource time at the pan-European pre-exascale supercomputer, LUMI. i-Tarmen metagenomes, here we come!
The year started with a lot of education related activities, but now some first research news in 2024: We have a new paper in Microbial Biotechnology, and indentified the (first?) species of the Lactobacillaceae, who transform the deoxyhexose rhamnose to propionate. We provide some first indication that propionate-containing fermentates act as antimicrobials against Salmonella. Have a look:

Find us in Copenhagen next week at the yearly Danish Microbiology Society Congress.
Watch out for Ker Sin Ng presenting on 'Environmental pH and compound structure affect the potential of short-chain carboxylic acids as antimicrobial metabolites' in Session 3 'Innovation through fermentation: microorganisms for food, feed and fun'
and posters of:
Angeliki Marietou 'Lactose addition increases expression of fecal microbiota beta-galactosidases and the fermentative production of butyrate independent of the presence of starter cultures' &
Mensure Elvan 'Deoxyhexoses as overlooked fermentation substrates for food microbes'
Yes, we published our last year's study on the fermentability of fucose (actively fermented) and fucoidan (not a gut microbe's favorite) by human fecal microbiota.
More to be found here:
https://academic.oup.com/femsec/article/99/10/fiad107/7287365?searchresult=1
More to come in the future, we will continue to work on exciting fucoidan and find ways to make it accessible to bacteria!
Ker Sin obtained a Short Term Research Grant from the Deutsche Akademische Austauschdienst (DAAD) to support her secondment at the Center for Biotechnology (CeBiTec) at the Universität Bielefeld. Congratulations Ker Sin, and enjoy your stay!
