As barley and oat production have recently increased in Canada, it has become prudent to investigate these cereal crops as potential feedstocks for alcoholic fermentation. Ethanol and other coproduct yields can vary substantially among fermented feedstocks, which currently consist primarily of wheat and corn. In this study, the liquified mash of milled grains from 28 barley (hulled and hull-less) and 12 oat cultivars were fermented with Saccharomyces cerevisiae to determine concentrations of fermentation products (ethanol, isopropanol, acetic acid, lactic acid, succinic acid, α-glycerylphosphorylcholine (α-GPC), and glycerol). On average, the fermentation of barley produced significantly higher amounts of ethanol, isopropanol, acetic acid, succinic acid, α-GPC, and glycerol than that of oats. The best performing barley cultivars were able to produce up to 78.48 g/L (CDC Clear) ethanol and 1.81 g/L α-GPC (CDC Cowboy). Furthermore, the presence of milled hulls did not impact ethanol yield amongst barley cultivars. Due to its superior ethanol yield compared to oats, barley is a suitable feedstock for ethanol production. In addition, the accumulation of α-GPC could add considerable value to the fermentation of these cereal crops.

In the present paper we describe a new carboxylic acid transporter in Escherichia coli encoded by the gene yaaH. In contrast to what had been described for other YaaH family members, the E. coli transporter is highly specific for acetic acid (a monocarboxylate) and for succinic acid (a dicarboxylate), with affinity constants at pH 6.0 of 1.24±0.13 mM for acetic acid and 1.18±0.10 mM for succinic acid. In glucose-grown cells the ΔyaaH mutant is compromised for the uptake of both labelled acetic and succinic acids. YaaH, together with ActP, described previously as an acetate transporter, affect the use of acetic acid as sole carbon and energy source. Both genes have to be deleted simultaneously to abolish acetate transport. The uptake of acetate and succinate was restored when yaaH was expressed in trans in ΔyaaH ΔactP cells. We also demonstrate the critical role of YaaH amino acid residues Leu131 and Ala164 on the enhanced ability to transport lactate. Owing to its functional role in acetate and succinate uptake we propose its assignment as SatP: the Succinate–Acetate Transporter Protein.

Methylation of sedosan (anhydro-sedoheptose) gives a tetramethyl sedosan, which on oxidation by nitric acid, yields an optically inactive trimethoxy glutaric acid. By esterifying the latter, and treating the ester with anhydrous methylamine, an optically inactive methylamide, presumably trimethoxy riboglutaro-dimethylamide is obtained. No trace of the methylamide of inactive dimethoxy succinic acid could be found. It is thus concluded that sedose possesses a 2:6 oxygen ring and that sedosan is an anhydro-sedopyranose.This is confirmed by the isolation of monotrityl sedosan, which shows that sedosan has only one primary alcohol group. Sedosan is therefore 2:7-anhydro-sedopyranose.The epimerisation of trimethyl δ-arabonolactone into trimethyl δ-ribonolactone apparently takes place only with great difficulty.The structure of sedosan is found to be in harmony with its lack of tendency towards polymerization, and this is in accordance with the views of Hibbert on the relation of structure to polymerization.
