Abstract

Un método para producir un producto de lignina purificada mediante un tratamiento enzimático, cuyo método comprende los pasos de: -proporcionar una mezcla que contenga lignina, ajustando y/o manteniendo el valor del pH de dicha mezcla en un valor óptimo para el tratamiento enzimático; -agregar al menos una enzima a dicha mezcla, donde dicha al menos una enzima esté dirigida a hidrolizar los carbohidratos presentes en dicha mezcla; -ajustar y/o mantener la mezcla en una temperatura óptima de trabajo, durante un período de tiempo óptimo de reacción para el tratamiento enzimático; y ?terminar el tratamiento enzimático.A method for producing a purified lignin product by an enzymatic treatment, the method of which comprises the steps of: - providing a mixture containing lignin, adjusting and / or maintaining the pH value of said mixture at an optimum value for the enzymatic treatment; - adding at least one enzyme to said mixture, wherein said at least one enzyme is directed to hydrolyze the carbohydrates present in said mixture; -adjust and / or keep the mixture at an optimum working temperature, for an optimal reaction time period for the enzymatic treatment; and? terminate the enzyme treatment.
