Abstract
The rapid growth of the global population will double protein demand by 2050. However, the conventional ways of protein production need large occupation of arable land and are associated with negative environmental impacts such as high greenhouse gas emissions, water pollution, and deforestation. This proof-of-concept study aims to develop and investigate a process that combines the strengths of microbial electrochemistry and microbial metabolisms to convert CO2 and surplus renewable electricity into single-cell protein. The results may provide insights into developing an alternative approach as a step forward to conventional farming for high-quality and carbon-neutral protein production by using renewable feedstocks and free from the arable land, which aligns with the Sustainable Development Goals (2, 12, 13, 15).
In this study:
• We realized CO2-to-protein in a two-stage bioinorganic electrosynthesis system.
• We clarified how key factors of CO2 inflow and voltage affected this bioconversion.
• We revealed the importance of O2-level control for maximizing protein production.
• This process with renewable feedstocks is independent of conventional agriculture.
