“…The experimental work focused on shifting the biological process into dark anaerobic conditions where hydrogenase-mediated H 2 formation reaction takes place. The BioCon CO 2 involves the formation of ethanol from biomass waste [101]. The experiment was effective in demonstrating the cyclic turnover of carbon, but more research was needed to produce fuel on a wide scale.…”

Excessive dependence on fossil fuels increases GHG emissions and carbon levels in the atmosphere, leading to climatic changes. This phenomenon can be reversed by capturing the carbon via “carbon capture and storage” (CCS) or “carbon capture and utilize” (CCU) technologies. In CCS methods, the captured carbon is stored in natural sinks (e.g., oceans), whereas, in CCU methods, the carbon is converted into useful products. Among CCU methods, the biological conversion of CO2 (BioConCO2) into value-added chemicals has gained great attention. This review focuses on providing an overview of the recent advances in CO2 utilization technology with a focus on the BioConCO2. The theoretical background and technical drivers, challenges, and setbacks of upscaling and commercialization of BioConCO2 are critically discussed with implications for future improvements. The BioConCO2 is increasingly attracting the attention of researchers and industrialists for its capacity to operate under low CO2 concentrations and in the presence of impurities (common conditions in industrial flue gases)—among other numerous advantages. While upscaling algae-based BioConCO2 has operational and financial challenges, bioconversion via bacteria and genetically engineered cyanobacterial seems promising due to their efficiency and flexibility.

“…Wastewaters are loaded with many types of microorganisms but are predominantly composed of bacteria with different roles in the water treatment system (Kumar et al, 2022). Some belong to functional genera, which are mainly responsible for the removal of pollutants in wastewater while others are potentially pathogenic bacteria, which can pose threats to public health and the environment (Fan et al, 2018).…”
