Tóm tắt

AbstractAn autoclavable All‐in‐One electrolysis electrode in a rod shape assembly is developed as a new tool for bioelectrochemical systems and electricity‐aided bioprocesses. It can replace the classic two‐chamber bioelectrochemical system for electrolysis reactions, be inserted into conventional bioreactors and is easily adaptable as electrocatalytic surface or generator of super‐fine bubbles (H2 and O2) for bioconversion processes. Whereas the bioreactor itself functions as the working electrode chamber, a well‐integrated inner counter electrode chamber enables water electrolysis without the normally encountered undesired ion‐transfer effect. The efficiencies of the electrode are characterized and its advantages and usefulness compared to the classic H‐Cell bioelectrochemical system (BES) are demonstrated with glycerol fermentations by Clostridium pasteurianum DSM 525.
