Job description

Vacancy PhD candidate in microbial protein production from biogas.

Ghent University is a world of its own. Employing more than 15,000 people, it is actively involved in education and research, management and administration, as well as technical and social service provision on a daily basis. It is one of the largest, most exciting employers in the area and offers great career opportunities. With its 11 faculties and more than 80 departments offering state-of-the-art study programmes grounded in research in a wide range of academic fields, Ghent University is a logical choice for its staff and students.

The Center for Microbial Ecology and Technology (CMET) ( is part of the Faculty of Bioscience Engineering at Ghent University, as well as part of CAPTURE ( CMET has over 40 years of experience in the study of applied microbial processes and microbial ecology in the contexts of waste(water) treatment, bioremediation, bioproduction and resource recovery. CMET is well recognized worldwide in its field, and links excellent basic science with application, leading to a high level of peer reviewed outputs besides commercial outcomes, including several spin-off companies over time. Reactor and process developments go from millilitre scale to full scale industrial.

A holistic approach to resource recovery from organic waste is critical for a successful bio-based circular economy in which anaerobic digestion for biogas production plays a central role. Currently, biogas is used for electricity production or upgraded to biomethane. In this project, we will consider a novel value chain for biogas towards the production of the high-value microbial biomass rich in protein or “microbial protein” towards animal feed and even food applications, using a specific microbial consortium that can use methane and/or carbon dioxide as carbon source. We will produce the microbial biomass, harvest it, process it, and use it for inland different feed trials. In this project we will, thus, create a novel valorisation route for biogas through the indirect conversion of organic waste into feed & food. A key emphasis will be placed on the operation of gaslift bioreactors at the lab-scale and pilot-scale.
