Despite worldwide attempts to reduce carbon dioxide (CO?) emissions, their rise persists, making it critical to explore other methods for addressing climate change. Microbial carbon fixation, which leverages the metabolic abilities of different microorganisms to convert CO? into useful bioproducts, is a promising sustainable approach. The efficacy and scope of CO? usage have significantly increased due to recent advancements in microbial biotechnology, particularly in technologies like microbial fuel cells (MFCs), bioelectrochemical systems (BESs), microbial electrolysis cells (MECs), and polyhydroxyalkanoate (PHA) production platforms. This review investigates the diversity of carbon-fixing microbes, advanced biotechnological techniques that increase their effectiveness, and the use of synthetic biology and metabolic engineering to enhance CO? capture. We also emphasize the potential prospects and the difficulties related to scaling up, with an emphasis on industrial and environmental uses. A comprehensive summary of new findings is presented, including data from forty important studies on this topic.
