“…Given the massive political interest in substituting part of the petroleum-based transportation fuels with fuels derived from cheap and plentiful renewable The 12 building blocks derived from the sugars that result by hydrolysis and saccharification of lignocellulusic biomass, exemplified by glucose (Murzin and Leino (2008)) resources -about 10 10 tons/year of lignocellulosic biomass appears to be relatively readily available worldwide -the subject of ethanol production from biomass has been treated in numerous journal papers, books, and pamphlets published by national and international organizations. The three recent reviews (Lin and Tanaka 2006;Hahn-H€ agerdahl et al 2006;Lynd et al 2008) give short, but well-balanced accounts of the prospects of ethanol production, technological as well as economic, from Japan, Sweden, and the USA.…”

For the past 80-90 years petroleum and natural gas have served as raw materials for the majority of the finished products of our daily lives. After World War II these raw materials decisively substituted coal, and they have been the foundation of an enormous increase in material wealth and welfare throughout the World.A few basic raw materials, petroleum, natural gas, þS from oil or natural gas, and O 2 þ N 2 from air, generate first primary (or platform) chemicals, next secondary (commodity) chemicals, then intermediates, and finally the finished products of virtually all industries that provide consumer goods.The aromatic fraction of petroleum delivers platform chemicals, such as propylene, ethyl benzene, cyclohexane, and cumene. These are used to synthesize secondary chemicals such as styrene, adipic acid, caprolactam, acetone, and terephthalic acid; and these in turn are raw materials for the polymer industry that produces textiles, packaging for food products, appliances, and communication equipment (pencils, inks, computer casings, optical fiber). The aliphatic fraction of petroleum contains other platform chemicals (iso-butylene, butadiene, etc.) that supplement the aromatic fraction to produce intermediates for the abovementioned industries. The transportation sector directly receives consumer goods from C 5 to C 14 aliphatic compounds, while products such as antifreeze and gasoline additives are derived by chemical processing of petroleum platform chemicals.Natural gas and cracked naphtha deliver other platform chemicals (ethylene, propylene, CO/H 2 , NH 3 ) for the solvent industry (methanol, ethanol, ethylene glycol, etc.), for the polymer industry (formaldehyde, polyethylene, polypropylene, PVC), and for fertilizers.Together the platform chemicals from petroleum and natural gas are combined to give most of the products of the health and hygiene industry, the housing industry, and the exploding recreation industry. Except for the input from the mining and the forest industry, and the inorganic platform chemicals (such as cement and phosphates) it is, indeed, hard to imagine the modern world without the crucial input from oil and gas.J.

Dark fermentation, also known as acidogenesis, involves the transformation of a wide range of organic substrates into a mixture of products, e.g. acetic acid, butyric acid and hydrogen. This bioprocess occurs in the absence of oxygen and light. The ability to synthesize hydrogen, by dark fermentation, has raised its scientific attention. Hydrogen is a nonpolluting energy carrier molecule. However, for energy generation, there is a variety of other sustainable alternatives to hydrogen energy, e.g. solar, wind, tide, hydroelectric, biomass incineration, or nuclear fission. Nevertheless, dark fermentation appears as an important sustainable process in another area: the synthesis of valuable chemicals, i.e. an alternative to petrochemical refinery. Currently, acetic acid, butyric acid and hydrogen are mostly produced by petrochemical reforming, and they serve as precursors of ubiquitous petrochemical derived products. Hence, the future of dark fermentation relies as a core bioprocess in the biorefinery concept. The present article aims to present and discuss the current and future status of dark fermentation in the biorefinery concept. The first half of the article presents the metabolic pathways, product yields and its technological importance, microorganisms responsible for mixed dark fermentation, and operational parameters, e.g. substrates, pH, temperature and head-space composition, which affect dark fermentation. The minimal selling price of dark fermentation products is also presented in this section. The second half discusses the perspectives and future of dark fermentation as a core bioprocess. The relationship of dark fermentation with other (bio)processes, e.g. liquid fuels and fine chemicals, algae cultivation, biomethane-biohythane-biosyngas production, and syngas fermentation, is then explored.

The preparation of optically pure fine chemicals is among the most important and challenging tasks met by organic chemists. Recently, significant efforts have been focused on the development of green and sustainable procedures for the synthesis of these high value-added compounds. Asymmetric heterogeneous catalysis has provided efficient solutions to these challenges. The application of heterogeneous chiral catalysts in one-pot processes combines the advantages of use of these materials with time, material, and energy savings associated with cascade or sequential procedures. This review surveys these asymmetric onepot reactions reported until July 2017, in which a heterogeneous chemical catalyst has been applied either as a single multifunctional catalyst or in combination with a second catalytically active material. These processes include one-pot procedures catalysed by carefully designed solids obtained by the immobilization of chiral metal complexes, by anchoring chiral organocatalysts, or by modifying catalytic surfaces with optically pure compounds, which may also incorporate uncatalyzed and homogeneously catalysed steps. Methods applying achiral heterogeneous catalysts in combination with soluble chiral chemical catalysts or biocatalysts are also presented. Sophisticated, finely tuned materials have been applied in most of these reactions, which have been discussed along with the main requirements necessary to perform these transformations in a one-pot manner.
