Abstract
LA PRESENTE INVENCION SE REFIERE A UN PROCESO DE TRATAMIENTO DE UNA PASTA LIGNOCELULOSICA POR UNA PREPARACION QUE CONTIENE ENZIMAS QUE TIENEN UNA ACTIVIDAD SOLUBILIZANTE DE LA LIGNINA Y EVENTUALMENTE UNA ACTIVIDAD HEMICELULOLITICA, DERIVANDO DICHAS ENZIMAS DE LA BACTERIA STREPTOMYCES VIRIDOSPORUS. ESTE TRATAMIENTO ENZIMATICO PUEDE SER APLICADO EN LA SEPARACION DE LA LIGNINA DE LA PASTA LIGNOCELULOSICA, POR EJEMPLO EN COMPLEMENTO DE UN PROCESO DE BLANQUEO.
