摘要： The present invention relates to method for a microbial fermentation process involving fermentation of a fermentation media derived from biomass to a target fermentation product. The method comprising: providing a reference curve defined by a predetermined weight ratio of galactose to xylose as a function of acetic acid concentration present in the fermentation media; providing a first biomass-based stream and a second biomass-based stream different to the first biomass-based stream, comprising galactose and xylose; mixing the first and second biomass-based streams; providing a fermentation media by treating the mixed first and second biomass-based streams, or treating the first and second biomass-based streams separately prior to the mixing, wherein the mixing of the first and second biomass-based streams results in a weight ratio of galactose to xylose in the fermentation media closer to the reference curve compared to at least one of the first and second biomass-based streams; and fermenting the fermentation media by means of fermentation microorganisms being a yeast able to ferment xylose, such that the xylose and galactose are simultaneously fermented into the same target fermentation product.

摘要： Disclosed herein are yeast strains and derivatives thereof, as well as compositions comprising the yeast strains for use in ethanol manufacture. The disclosure also relates to processes for producing ethanol from biomass using the yeast strains and compositions. In particular, the yeast strains produce lower glycerol and higher ethanol, and have a higher temperature tolerance and higher fermentation rate than strains and products currently used in ethanol production processes.

摘要： Fermented grain (11), such as brewer's grain or wet cake, which contains both hemicellulose and cellulose, is processed to provide sugars. The grain is first treated (14) with hot water to hydrolyse hemicellulose; and an aqueous phase (26) containing the products of the hydrolysis of hemicellulose is separated from particulate material. The particulate material is then fed (18) into a flow of steam at above 450°C along a reactor duct (20, 32) to form a flowing mixture of particles and vapours, the mass flow of steam being at least 3 times the mass flow of particulate matter, such that the particulate material is heated rapidly; and after no more than 3 seconds at least 75% (by mass) of the particles are separated (21) from the flowing mixture. The vapours of the flowing mixture are then condensed (22). The result is a sugar solution (25). Steady feeding of the particulate material may be achieved with an eductor (32) that includes a nozzle (36) for entry of the steam, and a sloping deflector plate (40) above it.
