Microbial conversion of cheap and problematic carbon sources, like CO 2 and CO, into fine chemicals offers a promising green alternative to numerous traditionally fossil fuel-based industries such as steel, cement, and pharmaceuticals production. Purple phototrophic bacteria (PPB) are emerging as versatile key players in carbon–neutral systems due to their anoxygenic photosynthesis and diverse metabolic capabilities, enabling...

Microbial conversion of CO 2 and CO into chemicals is a promising route that can contribute to the cost-effective reduction of anthropogenic green house and waste gas emissions and create a more circular economy. However, the biotechnological valorization of CO 2 and CO into chemicals is still restricted by the limited number of model microorganisms implemented, and the small profit margin of the products synthesized. This per...
