Dwindling petroleum feedstocks and increased Carbon dioxide (CO₂) concentrations in the atmosphere currently open the concept of using CO₂ as raw material for the synthesis of well-defined organic compounds. In parallel to recent advances in the chemical CO₂-fixation, enzymatic (biocatalytic) CO₂ conversion is currently being investigated at an increased pace. Enzyme catalytic reactions are found to be environmentally safe catalytic reactions in organic synthesis and, the efficient biocatalytic conversion of Carbon dioxide will help in reducing the greenhouse gas effect and in production of useful chemicals as well. The enzymatic approach for CO₂ conversion has attracted a lot of attention, due to its several advantages compared to conventional processes, such as high yields and selectivity under milder reaction conditions. A detailed search of published reports was done and analyzed in this paper, related to enzyme catalytic conversion of carbon dioxide into useful chemicals.
