Core Viewpoint - The article discusses the potential of carbon dioxide (CO2) as a resource for biomanufacturing, highlighting advancements in converting CO2 into valuable products such as starch, proteins, and biodegradable plastics, which can contribute to sustainable development and carbon neutrality [10][11][12]. Group 1: CO2 as a Resource - CO2 is not only a greenhouse gas but also a crucial raw material for biomanufacturing, participating in the global carbon cycle and supporting the food chain [11][12]. - The international community is increasingly focusing on how to convert CO2 into useful resources, shifting from passive emission reduction to active utilization [11][12]. Group 2: Advances in CO2 Conversion - Researchers have made significant progress in developing new pathways for CO2 conversion, including the design of artificial carbon fixation pathways that outperform natural processes [13][14]. - The first artificial synthesis of starch from CO2, achieved by the Chinese Academy of Sciences, demonstrates a method that does not rely on photosynthesis, utilizing chemical catalysis and enzymatic reactions [15][16]. Group 3: Industrial Applications - Microbial proteins are emerging as a sustainable protein source, with companies successfully converting CO2 or industrial waste gases into microbial protein, thus not competing with food resources [16]. - The development of biodegradable plastics from CO2 captured from seawater showcases the potential for large-scale production and addresses marine acidification [17]. Group 4: Future Implications - The exploration of CO2 bioconversion mechanisms and the development of efficient carbon fixation systems are recognized as significant scientific challenges, with the potential to reshape material production and contribute to carbon neutrality goals [17][18].
