Catalytic Conversion of Carbohydrates to Initial Platform Chemicals: Chemistry and Sustainability

The replacement of fossil resources that currently provide more than 90% of our energy needs and feedstocks of the chemical industry in combination with reduced emission of carbon dioxide is one of the most pressing challenges of mankind. Biomass as a globally available resource has been proposed as an alternative feedstock for production of basic building blocks, which could partially or even fully replace the currently utilized fossil-based ones in well-established chemical processes. The destruction of lignocellulosic feed followed by oxygen removal from its cellulose and hemicellulose content by catalytic processes results in the formation of initial platform chemicals (IPCs). However, their sustainable production strongly depends on the availability of resources, their efficient or even industrially viable conversion processes, and replenishment time of feedstocks. Herein, we overview recent advances and developments in catalytic transformations of the carbohydrate content of lignocellulosic biomass to IPCs (i.e., ethanol, 3-hydroxypropionic acid, isoprene, succinic and levulinic acids, furfural, and 5-hydroxymethylfurfural). The mechanistic aspects, development of new catalysts, different efficiency indicators (yield and selectivity), and conversion conditions of their production are presented and compared. The potential biochemical production routes utilizing recently engineered microorganisms are reviewed, as well. The sustainability metrics that could be applied to the chemical industry (individual set of sustainability indicators, composite indices methods, material and energy flow analysis-based metrics, and ethanol equivalents) are also overviewed as well as an outlook is provided to highlight challenges and opportunities associated with this huge research area.

“…It focuses on the aptitude of microorganisms to convert CO 2 into useful products. Biological fixation of CO 2 is a sustainable solution to reduce CO 2 content in biogas due to its nature which is environmentally-friendly and eliminates the step of captured CO 2 disposal [71]. One of the biological methods to utilize CO 2 in biogas relies on the utilization of H 2 for the conversion of CO 2 to CH 4 based on the action of hydrogenotrophic methanogens.…”

Technologies for Biogas Upgrading to Biomethane: A Review

et al. 2019

The environmental impacts and high long-term costs of poor waste disposal have pushed the industry to realize the potential of turning this problem into an economic and sustainable initiative. Anaerobic digestion and the production of biogas can provide an efficient means of meeting several objectives concerning energy, environmental, and waste management policy. Biogas contains methane (60%) and carbon dioxide (40%) as its principal constituent. Excluding methane, other gasses contained in biogas are considered as contaminants. Removal of these impurities, especially carbon dioxide, will increase the biogas quality for further use. Integrating biological processes into the bio-refinery that effectively consume carbon dioxide will become increasingly important. Such process integration could significantly improve the sustainability of the overall bio-refinery process. The biogas upgrading by utilization of carbon dioxide rather than removal of it is a suitable strategy in this direction. The present work is a critical review that summarizes state-of-the-art technologies for biogas upgrading with particular attention to the emerging biological methanation processes. It also discusses the future perspectives for overcoming the challenges associated with upgradation. While biogas offers a good substitution for fossil fuels, it still not a perfect solution for global greenhouse gas emissions and further research still needs to be conducted.

“…Generally, succinic acid is mainly synthesized from non-renewable petrochemical resources through chemical synthetic methods, which would cause severe environmental issues . Compared with chemical synthesis, biological production of succinic acid shows great potential, such as the utilization of renewable biomass, mild fermentation conditions, and fixation of CO 2 . , During various succinic acid producers, one of the most intensively investigated one is Actinobacillus succinogenes, which has the advantages of a wide substrate utilization spectrum including both pentose and hexose, high yield of succinic acid and tolerance to succinic acid, and so forth. , …”

Consolidated bioprocessing (CBP) has been considered as a cost-effective strategy for the efficient bioconversion of lignocellulosic biomass into valuable chemicals. Microbial consortium can complete the complex CBP process through the cooperation within different microorganisms. In this study, a proof-of-concept CBP microbial consortium was designed, which is composed of a hemicellulase-producing bacterium Thermoanaerobacterium thermosaccharolyticum M5 and a succinic acid production specialist Actinobacillus succinogenes 130Z. The continuous conversion of xylan to xylose by T. thermosaccharolyticum could maintain a high hydrolyzing rate, which would facilitate the following succinic acid production by A. succinogenes 130Z. After the process optimization including inoculation time, pH, and so forth, 32.50 g/L of succinic acid with a yield of 0.39 g/g was obtained from xylan through CBP, representing the highest succinic acid production directly from hemicellulose materials. In addition, 12.51 g/L of succinic acid was directly produced from 80 g/L of untreated corn cob. These results demonstrated that the proof-ofconcept application of this CBP-based microbial cocultivation system could be readily adopted for bioconversion of lignocellulosic biomass into other valuable biochemicals.
