This work proves for the first time the bioelectrochemical production of butyrate from CO2 as a sole carbon source. The highest concentration of butyrate achieved was 20.2 mMC, with a maximum butyrate production rate of 1.82 mMC•d-1. The electrochemical characterisation demonstrated that the CO2 reduction to butyrate was hydrogen driven. Production...

BACKGROUND Phosphorus (P) resources are limited, and to assure its supply, the coming actions must be focused on P‐recovery rather than its removal. In this sense, manure is a mining opportunity for nutrient recovery, for example, recovered as struvite. However, manure treatment is challenging due to its characteristics, such as the solid content,...
