    Abstract: A process for producing oligosaccharides from lignocellulosic biomass, having the following steps: a) pre-treating the biomass in a pre-treatment reactor (1) in order to provide an effluent containing a pre-treated substrate; b) enzymatic hydrolysis of the pre-treated substrate contained in the effluent from step a) in a reactor, in the presence of cellulases such that a hydrolysate containing glucose, cellulases and water is produced; c) removing at least a portion of the hydrolysate from step b) comprising a liquid fraction; d) reducing the water content of said portion of the hydrolysate in step c) such that the liquid fraction of the hydrolysate has a water content of less than 65% by weight with respect to the total weight of the liquid fraction; e) incubating the hydrolysate from step d) at a temperature in the range 40° C. to 70° C. for the time necessary to produce an effluent enriched in oligosaccharides.

    Abstract: The present invention concerns a process for the production of an aqueous mixture comprising isopropanol, n-butanol and ethanol, comprising a step in which an aqueous solution containing C5 and/or C6 sugars and acetate is fermented under strict anaerobic conditions in the presence of a fermenting microorganism of the genus Clostridium and in which said aqueous solution has an acetate concentration in the range 0.5 to 10 g/L and a ratio by weight of (acetate)/(sum of C5 and/or C6 sugars) in the range 0.005 to 0.35 g/g.

    Abstract: The process for the production of alcohol and/or solvent from a biomass feedstock comprises the stages for pretreatment (P) of the biomass feedstock, for enzymatic hydrolysis (H) of the pretreated substrate, and for fermenting the hydrolyzate (F).To reduce the size of the fermenters, at least a portion of the solid residue contained in the hydrolyzate is extracted (Ex1) in such a way as to obtain a stream of solid residue (9) comprising lignin and a hydrolyzate (8) that is low in solid residue. Then, the stream of solid residue is washed (L) with a liquid stream in such a way as to recover a sugar-enriched liquid stream (15). The sugar-enriched liquid stream (15) is recycled in the enzymatic hydrolysis stage (H) to be able to upgrade the sugars without providing dilution of the streams in the process.
