The use of bio-residues from agriculture for value addition is often limited, otherwise operators fear process instabilities. This hinders the closing of regional material cycles.
Dark fermentation optimised for short-chain carboxylic acid production has a great potential to adapt any undefined feedstock mixtures into small building blocks, which can be used to products of higher value. This process can be performed in plug-flow bioreactors. In order to achieve a higher efficiency and robustness, enzymes and microbes shall be added as identified in automated screening; the application of gradient measurements along the plug-flow reactor and polarizability measurements to assess the activity of microorganisms in several parts of the plug-flow bioreactor and in different scales shall contribute to new options for process control. The short-chain carboxylic acids from dark shall be used for the production of the polyunsaturated fatty acid docosahexaenoic acid (DHA) in a subsequent cultivation.
