Embodiments of the present disclosure involve systems and methods that inhibit the production of lactic acid during propagation of yeast and/or during hydrolysis of cellulose by including a sufficient amount of dissolved oxygen.

The present invention relates to a method for producing a food product comprising hydrolysed starch, as well as to products obtainable by the method. The method has the advantage of reducing the amount of sugar (i.e. maltose) produced by hydrolysis as compared to conventional methods of starch hydrolysis and present the additional advantage of providing good processability for the food product.

A process to produce a protein concentrate from grain, specifically barley protein concentrate (BPC) through mechanical and biochemical intervention while producing multiple sugar streams as co-products. The resulting BPC preferably contains 54%-95% protein derived exclusively from the enzymatically processed barley and has a pH>5.0. The BPC may contain approximately 10% oil, less than 5% crude fiber, less than 1% residual glucose, and less than 0.5% phytic acid. The BPC contains no ethanol, organic acid, fermentation products, or microbial cells or cell mass. No fermentation occurs in the production of the BPC. The BPC has unique applications in formulations for aquaculture or livestock feed, and other pet food as well as for food formulations intended for human consumption. The sugar co-products, including glucose, have applications in industry and science and are particularly suitable for use as feedstocks for fermentation processes, livestock feeds, or biochemical conversion processes.

Chimeric and other variant β-glucuronidase enzymes with enhanced properties as compared to unmodified enzyme are provided. The enzymes of the invention advantageously exhibit enhanced enzymatic activity, enhanced substrate range, enhanced pH range, enhanced temperature range and/or enhanced enzyme stability. Methods of using the variant enzymes for hydrolysis of glucuronide substrates, including opiates and benzodiazepines, are also provided.

A method for producing mono-ethylene glycol (MEG) from a wood-based raw material, and wherein method includes: i) providing a wood-based feedstock originating from the wood-based raw material and including wood chips, wherein at most 5 weight-% of the wood chips in the wood-based feedstock are overthick wood chips as specified by SCAN-CM 40:01, and subjecting the wood-based feedstock to at least one pretreatment to form a liquid fraction and a fraction including solid cellulose particles; ii) subjecting the fraction comprising solid cellulose particles to enzymatic hydrolysis to form a lignin fraction and a carbohydrate fraction; iii) subjecting the carbohydrate fraction to catalytical conversion to form a liquid composition of glycols; and iv) recovering mono-ethylene glycol from the liquid composition of glycols. Further is disclosed a corresponding arrangement and mono-ethylene glycol obtainable by the method.

The present invention relates to a process for treating a lignocellulosic biomass pretreated beforehand (1), said process comprising the extraction of the free sugars from said pretreated biomass using an alcoholic or aqueous-alcoholic extraction solution (2), so as to obtain a liquid phase enriched in free sugars, called liquor (3), and a solid phase depleted in free sugars, called must (4).

Provided are aqueous fermentation feedstocks comprising glucose monomers at a concentration of less than 50 gram/Liter (g/L) of the total feedstock, water-soluble dextrose oligomers at a concentration in a range between 50 g/L and 300 g/L of the total feedstock; and water. Further provided are methods of production thereof and uses thereof in the production of single cell protein and/or ethanol.
