Interest in biobutanol as a top-rated biofuel and industrial solvent has increased due to its high energy density, low water-absorbing properties, and compatibility with existing fuel infrastructure systems. Converting butyric acid derived from biomass to butanol using species of Clostridium presents a promising approach for recycling carbon and valorising waste. Despite advances, challenges persist due to low conversion efficiency, product inhibition, and metabolic limitations, hindering large-scale implementation. This research examines the microbial conversion of butyric acid into butanol by solventogenic Clostridium species in a controlled anaerobic fermentation process. The process was optimized by altering pH levels, initial butyric acid concentrations, availability of electron donors, and the duration of fermentation. Metabolic flux was redirected towards solventogenesis by controlling redox balance and selectively supplementing nutrients. Substrate consumption and product formation were quantified using analytical techniques such as gas chromatography and high-performance liquid chromatography. Significant improvements to fermentation conditions led to a substantial increase in butanol production, resulting in high butanol selectivity and a decrease in the formation of by-products. The fermentation of butyric acid utilized a two-step process. The first stage process of upgrading is esterification, where the butyric acid is reacted with an alcohol. Butyric acid is separated from methanol in the presence of an acid catalyst to form methyl butyrate and water. The second step is hydrogenolysis of the butyrate ester in the presence of Hydrogen and a metal catalyst. The ester C-O bond is broken by hydrogenolysis, and the intermediates are hydrogenated to obtain biobutanol, and the corresponding alcohol utilized in the esterification is reusable. Reaction temperatures are normally between 180 and 260°C at high hydrogen pressures. This process reduced fermentation time and enhanced carbon efficiency relative to conventional acetone-butanol-ethanol (ABE) fermentation. The results show that Clostridium sp. can effectively re-uptake butyric acid and convert it into butanol, which suggests a strong potential for combining acidogenic and solventogenic bioprocessing methods. The conversion of butyric acid to butanol by Clostridium sp. constitutes a feasible and environmentally friendly biotechnological process for the production of sophisticated biofuels. This approach underpins circular bioeconomy principles by integrating waste-derived volatile fatty acids with renewable fuel production. Advances in metabolic engineering and process integration could make biobutanol production more scalable and economically viable.
