“…The production of sustainable biobased butanol is achieved through the ABE pathway utilizing Clostridium spp. during the process of fermentation ( Vamsi Krishna, Bharathi, George Shiju, Alagesan Paari, & Malaviya, 2022 ). The optimal agricultural residues for ABE synthesis exhibit elevated levels of cellulose and hemicellulose while possessing reduced amounts of lignin ( Liu et al, 2022 ).…”

“…However, the challenges in syngas fermentation remain the low solubilities of H 2 and CO in water, which may result in gas-liquid mass transfer limitations, the poor alcohol-to-acid ratios and low product concentrations with wild-type strains, and the low biomass densities in submerged syngas fermentation resulting in low volumetric productivities [27]. Therefore, various studies have investigated the optimization of autotrophic cultivation conditions, including partial pressures of the syngas components (nutrient level), pressure, pH, medium composition, and temperature [4,14,28,29]. For instance, Clostridium aceticum can utilize CO as a sole source of carbon and energy.…”

Providing simultaneously autotrophic and heterotrophic carbon sources is a promising strategy to overcome the limits of autotrophic syngas fermentations. D-xylose and L-arabinose are particularly interesting as they can be obtained by the hydrolysis of lignocellulosic biomass. The individual conversion of varying initial concentrations of these pentoses and D-fructose as reference was studied with C. autoethanogenum in fully controlled stirred-tank reactors with a continuous syngas supply. All mixotrophic batch processes showed increased biomass and product formation compared to an autotrophic reference process. Simultaneous CO and D-xylose or L-arabinose conversion was observed in contrast to D-fructose. In the mixotrophic batch processes with L-arabinose or D-xylose, the simultaneous CO and sugar conversion resulted in high final alcohol-to-acid ratios of up to 58 g g−1. L-arabinose was superior as a mixotrophic carbon source because biomass and alcohol concentrations (ethanol and 2,3-butanediol) were highest, and significant amounts of meso-2,3-butanediol (>1 g L−1) in addition to D-2,3-butanediol (>2 g L−1) were solely produced with L-arabinose. Furthermore, C. autoethanogenum could not produce meso-2,3 butanediol under purely heterotrophic conditions. The mixotrophic production of meso-2,3-butanediol from L-arabinose and syngas, both available from residual lignocellulosic biomass, is very promising for use as a monomer for bio-based polyurethanes or as an antiseptic agent.

“…Enzymatic catalysis currently only exists on a lab scale [ 36 , 37 ]. Although biobutanol production is also possible by sugar fermentation from sugar cane, corn, wheat, and other food crops, it is limited by lower productivity and yields, product inhibition, and high costs [ 11 , 16 , 18 , 38 ].…”

“…Many Clostridia are natural butanol producers and possess the ability to metabolize a variety of different substrates. However, similar to its first-generation predecessor, the process is limited by low butanol titers and product inhibition [ 11 , 16 , 18 , 38 ]. Typically, butanol is produced via ABE fermentation, which results in solvents in ratio of 3 parts acetone, 6 parts butanol, and 1 part ethanol, and butanol refinement is not an energetically favorable solution.…”

The steady increase in human population and a rising standard of living heighten global demand for energy. Fossil fuels account for more than three-quarters of energy production, releasing enormous amounts of carbon dioxide (CO2) that drive climate change effects as well as contributing to severe air pollution in many countries. Hence, drastic reduction of CO2 emissions, especially from fossil fuels, is essential to tackle anthropogenic climate change. To reduce CO2 emissions and to cope with the ever-growing demand for energy, it is essential to develop renewable energy sources, of which biofuels will form an important contribution. In this Essay, liquid biofuels from first to fourth generation are discussed in detail alongside their industrial development and policy implications, with a focus on the transport sector as a complementary solution to other environmentally friendly technologies, such as electric cars.
