[Microbial production of food compounds with carbon dioxide and derived low-carbon molecules as substrates]

The construction and optimization of microbial cell factories are crucial steps and key technologies in achieving green biomanufacturing. As concern has been aroused regarding the excessive carbon dioxide (CO₂) emissions and food security, a new and promising research field, microbial conversion of CO₂ into food compounds, has emerged. The research in this field not only holds significant implications for achieving the carbon peaking and carbon neutrality goals but also plays a role in maintaining food security. This paper provides a comprehensive review and outlook of the research on utilizing CO₂ and its derived low-carbon chemicals for the production of food compounds, focusing on the production of glucose, sugar derivatives, and single-cell proteins and the development of artificial CO₂ fixation pathways.
