research project "Multi-Digestome Overclocker"

Multi-Digestome Overclocker: Development of a multi product fermenter with QuorumSensing based biocenosis overclocking

Within the framework of the ZIM network Biomass 2.0, the Institute for Waste and Environmental Economics at the Technical University of Dresden is participating in a research project focusing on a novel three-stage digestion plant, the "MultiDigestome Overclocker". The word "overclocker" refers to an aspired biocoenosis overclocking. MultiDigestome is derived from the English word "microbiome" and refers to the idea of functionally linking multiple process biocoenoses.

Participating in the project is the Robert Boyle Institute e. V., the company BioenergieBeratungBornim GmbH, and the company AEV Energy GmbH. The new plant concept is to focus on the provision of succinic acid, hydrogen and methane. There is also a strong focus on the possibility of supplying energy according to demand.

At the succinic acid synthesis stage, the possibility of biological gas purification is also investigated in order to improve the quality of the methane produced. In order to facilitate the extraction of valuable metabolic substances, it is planned to feed the plant exclusively with liquid substrates, which are pressed out of the corresponding substrates previously. In addition, signalling molecules available on the market will be investigated in order to determine their suitability for the biocoenosis overclocking target.
