Biorefineries are set to become an important agent in the shift towards a circular economy due to their potential to valorize organic wastes into marketable products. Anaerobic fermentations yielding volatile fatty acids (VFA) are a key process in this biorefinery paradigm as VFA act as intermediates between the organic wastes and the final biorefinery products. However, the development of a new bioprocess based on mixed-culture fermentation is an extremely challenging task. Targeting the desired ...

Model-based design of a biorefinery platform to valorise agrifood organic waste into odd-chain volatile fatty acids integrating technical and environmental criteria

The conversion of organic wastes by anaerobic fermentation (the so-called carboxylate platform) is one of the promising emerging biorefineries that allows valorising organic carbon to volatile fatty acids (VFA), which can be further processed as chemicals, biopolymers and biofuels. A major obstacle to the widespread of the carboxylate ...

Batch cultures of designed media inocculated with biomass from WWTP anaerobious fermentation steps. The media consisted of a series of macro- and micro-nutrients to avoid limitations on proliferation, and a fermentative substrate of glucose and aminoacids. The glucose proportion and aminoacid composition varied culture to culture according to previous work using a mathematical model of a mixed culture fermentation in similar conditions. Acetoclastic methanogenesis was avoided with BES at 1 ...
