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 кислород потребляется в количествах, соответствующих от 20 до 5000 ммоль молекулярного кислорода на килограмм глюкана, присутствующего в лигноцеллюлозном материале, кислород добавляют после предварительной обработки и до и/или во время ферментативного гидролиза лигноцеллюлозного материала, предпочтительно в количестве, соответствующем по меньшей мере 30 ммоль молекулярного кислорода на килограмм глюкана, присутствующего в лигноцеллюлозном материале, более предпочтительно в количестве, соответствующем по меньшей мере 40 ммоль молекулярного кислорода на килограмм глюкана, присутствующего в лигноцеллюлозном материале, и наиболее предпочтительно в количестве, соответствующем по меньшей мере 50 ммоль молекулярного кислорода на килограмм глюкана, присутствующего в лигноцеллюлозном материале.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 oxygen is consumed in amounts corresponding to 20 to 5000 mmol of molecular oxygen per kilogram of glucan present in the lignocellulosic material, oxygen is added after pretreatment and before and / or during the enzymatic hydrolysis of the lignocellulosic material, preferably in an amount corresponding to at least 30 mmol molecular oxygen per kilogram of glucan present in the lignocellulosic material, more preferably in an amount corresponding to at least 40 mmol of molecular oxygen per kilogram of glucan present in the lignocellulosic material, and most preferably in an amount corresponding to at least 50 mmol of molecular oxygen per kilogram of glucan present in the lignocellulosic material.
