Bioconversion of Carbon Dioxide to Value-Added Products Using Saccharomyces Cerevisiae

This paper investigates and identifies within 20 bacterial strains an adept microorganism to effectively bioconvert carbon dioxide (CO2) to added value products. Among these microorganisms, Saccharomyces cerevisiae and Clostridium autoethanogenum emerged as promising candidates for their proficiency in converting CO2 into biofuel. Utilizing strategic acclimatization techniques, including anaerobic inoculum cultivation, the research team aimed to enhance the adaptability and efficiency of microorganisms in utilizing CO2 as feedstock for chemical production. The results were promising, particularly with the strain M. trichosporium, exhibiting commendable catalytic capabilities in reducing CO2 to valuable products. This study underscores the pivotal role of microbial biocatalysts in driving sustainable chemical transformations, establishing a framework for a “biorefinery” where diverse biochemical pathways converge to yield highvalue products from industrial waste streams. The bioconversion process achieved a significant CO2 conversion rate of 54.67%, coupled with a methanol purity exceeding 98.37%. The implications extend to the chemical industry's trends, promoting the use of bio-based building blocks for sustainability and economic viability, with potential annual reductions of CO2 by 64.4 metric tons.
