Abstract: A process for preparing lactic acid and/or a lactate salt via the fermentation of carbohydrates obtained from lignocellulosic material. In particular the process includes: a) treating a lignocellulosic material with an alkaline agent including a caustic magnesium salt in the presence of water to provide a treated aqueous lignocellulosic material; b) saccharifying the treated aqueous lignocellulosic material in the presence of a hydrolytic enzyme to provide a saccharified aqueous lignocellulosic material including fermentable carbohydrates and a solid lignocellulosic fraction; c) fermenting the fermentable carbohydrates in the saccharified aqueous lignocellulosic material by way of lactic acid producing microorganism in the presence of an alkaline agent including a caustic magnesium salt to provide an aqueous fermentation broth including a magnesium lactate; and d) isolating lactic acid and/or lactate salt from the fermentation broth; wherein the saccharification step b) and the fermentation step c) are performed as two separate steps.

Abstract: The present invention relates to regulation of the p H of a liquefaction process. Presented is a method for treatment of a biomass feedstock wherein the biomass feedstock is subjected to liquefaction, at a p H of at most 4, by treatment with hot compressed liquid water (HCW) at subcritical and/or supercritical conditions to improve the conversion efficiency. The present invention is also directed to quenching of a liquefaction process according to above, preventing, minimizing or eliminating clogging and/or fouling of sticky biomass components in process equipment during processing as according to above, and to the use of additives in a biomass liquefaction process.

Abstract: There is disclosed a method for processing a biomass (for example straw) containing lignocellulose such that cellulose and hemicellulose are made accessible for further processing, typically by decomposition, without needing energy-consuming dissolution of the biomass in water. The method includes repeated compressions of the biomass in a reciprocating piston press, where loose biomass is continuously fed into a piston chamber in front of a piston which moves the loose biomass into a tubular reaction chamber in which the biomass is compressed for producing a vapor explosion and autohydrolysis under simultaneous displacement of compressed biomass through the reaction chamber. After compression, to the biomass can be added fluid livestock manure, fluid waste water sludge etc. in a biogas plant for subsequent biogas processing.
