A high pressure (200 bar) CO2-H2O process was developed for pretreating lignocellulosic biomass at high-solid contents, while minimizing chemical inputs. Hardwood was pretreated at 20 and 40 (wt.%) solids. Switchgrass, corn stover, big bluestem, and mixed ...
Abundant in nature lignocellulosic plant biomass represent a promising, sustainable, source of energy as it can be converted into fuel ethanol through the fermentation of one of its prevalent sugar constituents – xylose. Xylose-utilizing recombinant Saccha ...
Face to the increasing demand for energy, the declining availability of fossil fuels and the periodical tensions in the geopolitical context of oil-producing countries have raised serious concerns in the governments worldwide as well as in the public opini ...
Nitrogen-in-the-ring analogues of L-fucose and L-rhamnose were prepared, which feature a spirocyclopropyl moiety in place of the methyl group of the natural sugar. The synthetic route involved a titanium-mediated aminocyclopropanation of a glycononitrile a ...
In solution-state NMR spectroscopy, dynamic processes can be probed provided the nuclear relaxation rate constant does not exceed the rate constant of the process. Phenomena occurring on a time scale longer than the spin-lattice relaxation time constant, T ...
Xylose fermentation from lignocellulosic material using recombinant yeast cells is a promising resource for efficient ethanol production as a future sustainable energy supply. Experimental approaches emphasize the engineering of xylose-utilizing recombinan ...
Although alcohols are well-known to be protein denaturants when present at high concentrations, their effect on proteins at low concentrations is much less well characterized. In this paper, we present a study of the effects of alcohols on protein stabilit ...
Glycoproteins and glycolipids are major components of the outer surface of mammalian cells. Their carbohydrate moieties, which are directed into the outer environment, serve as ligands for receptor proteins, such as lectins, pathogen proteins and antibodie ...
The one-step conversion of cellulose to C6-alcs. via green and energy efficient approaches has, as far as we are aware, not been reported. Such a process presents a considerable challenge, the two key problems being (1) finding a suitable solvent that diss ...
Alcohols, phenols and carboxylic acids are silylated with very good yields in the presence of silyl methallylsulfinates under non- basic conditions and with the formation of volatile co-products. ...
