In August 2017, within the scope of our collaborative project ERA-IB-15-109 ‘Z-Fuels’ (A novel bacterial system with integrated micro-bubble distillation for the production of acetaldehyde), a colleague from the University of Sheffield, Ali Mulakhudair, visited our Laboratory of Microbial bioenergetics for a short practical training course in cultivation and cloning methods for bacterium Zymomonas mobilis.
