A focused team of researchers led by Prof. Barth F. Smets, pursuing Microbial Resource Management and Engineering activities. We work at the interface between environmental engineering and microbial ecology. The main topics we explore are: the engineered nitrogen cycle, water treatment biotechnology, gene flows in microbial communities. We work from the cell scale to the communities and system scales, using complementary approaches (bioreactors operation, microscopy, molecular community description, modelling, etc.)


Come to Canada this June and learn how to mitigate N2O emissions from phase isolated nitrogen removal system at the next ICA conference in Quebec, were Borja will be representing us. Also, check how to monitor your settlers and photobioreactors.

Check the effect of heterotrophs on N2O production during nitrification in our latest article in Biotechnology and Bioengineering. How should we interpret the processes of microbial invasion? Find out by reading our latest perspective in ISMEJ. Also just available online: "Metagenomic analysis of rapid gravity sand filter microbial communities suggests novel physiology of Nitrospira spp." identifying commamox Nitrospira as major players in groundwater fed rapid sand filter. Dive deeper in the microbial world of sand filters with our recent paper: Ecological patterns, diversity and core taxa of microbial communities in groundwater-fed rapid gravity filters.

The R-code for An improved method to set significance thresholds for β diversity testing in microbial community comparisons is now also available online here and as github repository.
