The present project pursues an ambitious overall objective aimed at the sustainable development and utilisation of innovative biotechnological processes for the efficient use of low woody biomass. The focus is on the cultivation of Cupriavidus necator, Clostridia and Ustilago maydis in robust and scalable processes for the production of humulene, butyric acid and itaconic acid as well as the extraction of enzymes, each of which is to be established on a pilot plant scale. The robustness of a bioprocess is generally defined as its ability to tolerate fluctuations in the starting materials and process changes. In this context, robustness means that these fluctuations should have as little negative impact as possible on the resulting quantity and quality of the products. As fluctuations in the composition of the starting materials cannot be avoided, they must be taken into account during process development. The use of pressed juices as an energy-efficient substrate forms the basis for the realisation of a future-proof, resource-conserving and sustainable biotechnology.
