Abstract

Изобретение относится к способу получения продукта ферментации из лигноцеллюлозного материала, включающему следующие этапы: (a) необязательно, предварительной обработки лигноцеллюлозного материала; (b) необязательно, промывания необязательно подвергнутого предварительной обработке лигноцеллюлозного материала; (c) ферментативного гидролиза необязательно промытого и/или необязательно подвергнутого предварительной обработке лигноцеллюлозного материала с применением ферментной композиции, включающей по меньшей мере две целлюлазы, и при этом ферментная композиция, по меньшей мере, содержит ЛПМО, и необязательно очистки гидролизованного лигноцеллюлозного материала, (d) ферментации гидролизованного лигноцеллюлозного материала до получения продукта ферментации, и (e) необязательно, извлечения продукта ферментации; где количество образованных гидролизованных продуктов окисления в конце ферментативного гидролиза путем окисления ЛПМО лигноцеллюлозного материала, содержащего целлюлозу и/или целлоолигосахариды, поддерживают от 3 до 80 г/кг глюкана, присутствующего в лигноцеллюлозном материале, путем добавления подходящего количества кислорода после предварительной обработки и до и/или во время ферментативного гидролиза к лигноцеллюлозному материалу; предпочтительно образующимся гидролизованным продуктом окисления является глюконовая кислота, альдоновая кислота и/или геминальный диол, более предпочтительно гидролизованным продуктом окисления является глюконовая кислота.The invention relates to a method for producing a fermentation product from lignocellulosic material, comprising the following steps: (a) optionally, pretreating the lignocellulosic material; (b) optionally washing the optionally pretreated lignocellulosic material; (c) enzymatic hydrolysis of the optionally washed and / or optionally pretreated lignocellulosic material using an enzyme composition comprising at least two cellulases, and wherein the enzyme composition at least contains LMPO, and optionally purifying the hydrolyzed lignocellulosic material, (d ) fermenting the hydrolyzed lignocellulosic material to obtain a fermentation product, and (e) optionally recovering the fermentation product; where the amount of formed hydrolyzed oxidation products at the end of the enzymatic hydrolysis by oxidizing the LMPO of the lignocellulosic material containing cellulose and / or cellooligosaccharides is maintained from 3 to 80 g / kg of glucan present in the lignocellulosic material by adding a suitable amount of oxygen after pretreatment and before and / or during enzymatic hydrolysis to lignocellulosic material; preferably the resulting hydrolyzed oxidation product is gluconic acid, aldonic acid and / or geminal diol, more preferably the hydrolyzed oxidation product is gluconic acid.
