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.

Abstract: A process for producing cellulolytic and/or hemicellulolytic enzymes with a strain of microorganism belonging to the family of filamentous fungi. The process includes growing the fungi in an aqueous culture medium, in the presence of at least one carbon-based growth substrate, in a stirred and aerated bioreactor. It also includes the production of enzymes, starting with the aqueous culture medium in the presence of at least one inductive carbon-based substrate and also inducing the production of hydrophobins. Further, at least a portion of the hydrophobins produced in step (b) are reintroduced into the growth step (a).

Abstract: The invention relates to a process for treating lignocellulosic biomass by means of an acidic liquor in order to produce “second-generation” (2G) sugary liquors. These sugary liquors may be used to produce other products via a biochemical pathway (e.g. alcohols such as ethanol, butanol or other molecules, for example solvents such as acetone, etc.). This process comprises analysis of the liquid streams withdrawn during the process and adjustment of the composition of the impregnation liquor so as to keep the acidic power of said streams constant.

Abstract: The invention relates to a process for treating a lignocellulosic biomass comprising a solids content of not more than 80% by weight, said process comprising the use of at least one reactor (9,14) for treating said biomass, in which the or at least one of said reactors is fed with biomass via a feed means (6,11) creating a pressure increase between the biomass inlet and the biomass outlet of said feed means, in which said feed means is washed by circulation of a washing fluid between a washing inlet (7,12) and a washing outlet (8,13). According to the process, at least a portion of the washing fluid (8,13) exiting the fluid outlet of the at least one feed means (6,11) is reintroduced into the washing inlet of the same feed means or of another of said feed means.
