Abstract
Se proporciona un método para controlar contaminantes orgánicos, tales como xilanos, brea o ambos, que interfieren con el blanqueo de fibras y/o causan otras interferencias en los sistemas de fabricación de papel. El método incluye poner en contacto las fibras antes de cualquier blanqueo de las mismas con una composición que contiene una enzima hemicelulolítica y un adyuvante de remoción de contaminantes orgánicos para liberar los contaminantes orgánicos de las fibras. Las fibras tratadas luego se pueden blanquear y además utilizar, por ejemplo, en la fabricación de papel. La presente invención también se relaciona a las composiciones de tratamiento y a los productos de papel hechos con los materiales de fibra tratados con estas composiciones. También se proporcionan un método para aumentar la degradación enzimática de un sustrato, así como formulaciones y sistemas para lograr los mismos. Varios sustratos se pueden degradar o de otra manera procesar, incluyendo biomasa, lodo de molino de papel, y cuero de animal. La degradación enzimática puede ser aumentada al incluir uno o más surfactantes poliméricos.
