Light-Independent Biological Conversion of CO2

Abstract

Sevcan Erşan is a postdoctoral researcher at UCLA. Previously, she conducted postdoctoral research at the University of Hohenheim in Germany. She received her PhD in biotechnology from Yeditepe University, Turkey, and her bachelor’s and master’s degrees in food engineering from Istanbul Technical University, Turkey. She is experienced in waste utilization, bioprocessing technologies, and biological activities associated with phytochemicals. Her current research focuses on natural product chemistry and sustainable biotechnology. Junyoung Park is an assistant professor of Chemical and Biomolecular Engineering and co-director of the Metabolomics Center at UCLA. His research group focuses on systems-level analysis of metabolic networks to elucidate regulatory mechanisms and engineer metabolism. He aims to apply this knowledge to solving energy and environmental problems and curing human diseases such as cancer and diabetes. Before moving to Los Angeles, he conducted postdoctoral research at MIT. He received his bachelor’s degrees in mathematics and bioengineering from UC San Diego and a master’s and PhD in chemical engineering from Princeton University.

Effect of electron donors on CO2 fixation from a model cement industry flue gas by non‐photosynthetic microbial communities in batch and continuous reactors

“…Since non-photosynthetic microorganisms rely on the use of chemical energy instead of light to carry out the CO 2 reduction, the use of an adequate energy and reducing power source is key for the CO 2 fixation and conversion (Erşan & Park, 2020) ) and metal (i.e., Fe 2+ and Mn 2+ ) compounds serve as electron donors for these bacteria (Labrenz et al, 2005). Although H 2 has been recognized as an efficient electron donor (Claassens et al, 2018), currently it is valorized as an important feedstock in industry and as a clean biofuel (Mah et al, 2019); therefore, in this study it was not considered for its evaluation.…”

“…low efficiency and suffers from difficulties while operating in continuous mode on large scale [48,64] Dependence on sunlight limits its tractability and scalability [65] Methanation process is considered to be kinetically slow and suffers from poor mass transfer [55] …”

Ag Nanoparticle-Decorated GaN/β-Ga2O3 Core–Shell Nanowires as Catalysts for Highly Efficient CO2-to-CO Photocatalytic Conversion

“…Various methods for CO 2 utilization have been developed, − with artificial photosynthesis emerging as a particularly promising avenue for converting CO 2 into valuable carbon forms (e.g., CO, CH 4 , HCOOH, HCHO, etc.) through the use of sunlight and water. − Compared to biological or photoelectrochemical conversion methods, the process occurs at mild conditions (room temperature and ambient pressure) without requiring an external power source . However, challenges arise due to the inherent inertness of CO 2 molecules, the high CO bond energy (750 kJ mol –1 ), and the intricate electron transfer reactions, which limit the efficiency and selectivity of CO 2 photocatalytic conversion .…”
