“…The major sources of this kind of raw material are agricultural residues and wastes, such as rice straw, wheat straw, wood (hardwood), byproducts left over from the corn milling process (corn strover), annual and perennial crops, waste paper and sweet sorghum. These raw materials comprise three types of main biopolymers: cellulose, hemicellulose, and lignin [24].…”

This review paper presents the current state of the art on maleic acid synthesis from biomass-derived chemicals over homogeneous or heterogeneous catalysts. It is based on the most recent publications on the topic, which are discussed in details with respect to the observed catalytic performances. The recent developments and the technical drawbacks in the gas and the liquid phases are also reported. In addition, recent results on the mechanistic aspect are discussed giving insights into the probable reaction mechanisms depending on the starting molecule (furan, furfural and 5-hydroxymethylfurfural).

“…The solventogenic clostridia, Clostridium acetobutylicum and C. beijerinckii have been most commonly used for acetone-butanol-ethanol (ABE) fermentations, although the use of other strains including Clostridium pasteurianum, C. sporogenes, C. saccharobutylicum, and C. saccharoperbutylacetonicum has also been reported [37]. The ABE fermentation is characterized by low productivity because of low cell concentration and product inhibition giving a maximum total solvent (ABE) concentration in the range of 20 g/L.…”

Anaerobic microorganisms present in diverse ecological niches employ alternative strategies for energy conservation in the absence of oxygen which enables them to play a key role in maintaining the global cycles of carbon, nitrogen, and sulfur, and the breakdown of persistent compounds. Thereby they become useful tools in industrial and environmental biotechnology. Although anaerobes have been relatively neglected in comparison to their aerobic counterparts, with increasing knowledge about their diversity and metabolic potential and the development of genetic tools and process technologies to utilize them, we now see a rapid expansion of their applications in the society. This chapter summarizes some of the developments in the use of anaerobes as tools for biomass valorization, in production of energy carriers and chemicals, wastewater treatment, and the strong potential in soil remediation. The ability of several autotrophic anaerobes to reduce carbon dioxide is attracting growing attention as a means for developing a platform for conversion of waste gases to chemicals, materials, and biofuels.

“…Butanols are used in various applications such as solvents and fuel additives. [6,7] As it is well known that 1-butanol can be synthesized selectively from biomass resources by fermentation, [7] we focus on 2-butanol because it has a variety of applications, [6] for example, as a solvent, cleaner, and intermediate of ethyl methyl ketone, and has also received attention as a fuel or fuel additive because of its high octane number and low boiling point. [8] Conventionally, 2-butanol is produced by the hydration of 1-butene and 2-butene, which are obtained from the naphtha fraction in the petroleum refinery.…”

Synthesis of 2‐Butanol by Selective Hydrogenolysis of 1,4‐Anhydroerythritol over Molybdenum Oxide‐Modified Rhodium‐Supported Silica

Rh-MoOx /SiO2 (Mo/Rh=0.13) is an effective catalyst for the hydrogenolysis of 1,4-anhydroerythritol (1,4-AHERY) and provides 2-BuOH in high yield of 51 %. This is the first report of the production of 2-BuOH from 1,4-AHERY by hydrogenolysis. 1,4-AHERY was more suitable as a starting material than erythritol because the 2-BuOH yield from erythritol was low (34 %). Based on the kinetics and comparison of reactivities of the related compounds using Rh-MoOx /SiO2 and Rh/SiO2 catalysts, the modification of Rh/SiO2 with MoOx leads to the high activity and high selectivity to 2-BuOH because of the generation of reactive hydride species and the strong adsorption of 1,4-AHERY on MoOx species. The reaction proceeds by main two routes, (I) the combination of single C-O hydrogenolysis with the desorption of intermediates, a usual route in hydrogenolysis, and (II) multiple C-O hydrogenolysis without the desorption of intermediates from the active site, and the reaction mechanism for Route (II) is proposed.
