Microbial Biotechnology

We conduct research in microbial biotechnology with a focus on anaerobic microorganisms and bioprocesses. Our work aims to advance fundamental understanding of microbial metabolism and ecology, with particular emphasis on the links between microbial diversity, function, and process performance. Our research spans from the isolation and characterization of novel microorganisms to the optimization of laboratory-scale and full-scale bioprocesses. Microbes in focus includes, cellulose degraders, acetogens, syntrophs and methanogens. We use anaerobic cultivation and different molecular and bioinformatic methods, some of which are developed within our group. Our laboratory is equipped with different bioreactors ranging from 500 ml to 40 L, and we work closely with industry to study and optimize full-scale systems.

Biogas processes are one major focus of our research. We study the microorganisms driving biogas production, evaluate different substrates and reactor designs, and develop strategies to improve process efficiency. We also explore new applications and synergies with other bioprocesses and energy systems, such as organic acid production and integration with wind power. Additionally, some research addresses digestate quality and its use as fertilizer, including questions related to bioplastic degradation and spreading of weed seeds and antibiotic resistance. The work is carried out in collaboration with both academic and industrial partners and partly within the national platform BSRC. We also study the methane formation process in various other environments, such as in the rumen of cows and in rice fields.
