Additionally, the development of robust microbial strains through genetic and metabolic engineering could optimize CO2 fixation rates and product yields, making these technologies economically viable for large-scale deployment. The future of microbial processes in sustainable industrial practices looks promising, with microbial CO2 fixation and conversion technologies poised to play a critical role in addressing climate change and promoting green manufacturing. The continuous advancements in understanding microbial metabolic pathways, coupled with innovations in genetic engineering and bioelectrochemical systems, are likely to drive the development of more efficient and cost-effective CO2 fixation processes. As these technologies mature, they could be integrated into various industrial applications, from biofuel production to the synthesis of high-value chemicals, thereby contributing to a circular carbon economy and reducing our reliance on fossil fuels. The collaborative efforts of researchers, industry stakeholders, and policymakers will be essential in realizing the full potential of microbial CO2 fixation technologies and ensuring their successful implementation in sustainable industrial practices.
