An important milestone was achieved in January 2020 with the start-up of the state-of-the-art gas fermentation facility at the ERA Chair of Gas Fermentation Technologies (GasFermTEC). The facility enables to carry out gas fermentation experiments in strictly-controlled environmental conditions (both in bottles and in bioreactors) and our fermentation systems provide detailed characterisation of cell growth through on-line monitoring of culture conditions including off-gas analysis using an on-line mass-spectrometer. The facility was built and equipped according to the highest safety standards.
