An approach to industrial application: influence of black liquor and pH on xylanase efficiency in bleaching of eucalyptus kraft pulp
Fillat Latorre, Úrsula; Roncero Vivero, María Blanca; Bassa, Alexandre; Sacón, Vera Maria (American Chemical Society (ACS), 2010-11-17)
Article
Accés restringit per política de l'editorialTo obtain a more realistic appraisal of the potential efficiency of xylanases in the industrial bleaching, the influence of pH and the presence of black liquor (measured as COD) on the bleaching efficiency of two commercial ... -
Aplicación de biotecnología para la obtención de pastas de alta calidad. Estudio de sistemas enzimáticos en secuencias de blanqueo respetuosas con el medio ambiente
Fillat Latorre, Úrsula (Universitat Politècnica de Catalunya, 2008-06-30)
Tesi
Accés obertLa presente tesis parte del interés de blanquear pasta de lino (Linum usitatissimum) mediante procesos más respetuosos con el medio ambiente, a partir de secuencias totalmente libre de cloro (TCF) y de la utilización de ... -
Biobleaching of high quality pulps with laccase mediator system: influence of treatment time and oxygen supply
Fillat Latorre, Úrsula; Roncero Vivero, María Blanca (Elsevier, 2009)
Article
Accés obertIn this study we examined the influence of the treatment time and addition of oxygen on the efficiency of a laccase mediator system (L) applied to flax pulp at atmospheric pressure. The redox potential and the dissolved ... -
Effect of commercial xylanases applied at extreme conditions in a eucalyptus pulp mill
Fillat Latorre, Úrsula; Roncero Vivero, María Blanca; Bassa, Alexandre; Sacón, Vera Maria (2012-10)
Article
Accés restringit per política de l'editorialIn this study, we examined the effect of treating eucalyptus pulp with various commercial xylanases to identify the most effective enzyme for use under the industrial bleaching conditions used at the Jacareí mill of the ... -
Effect of process parameters in laccase mediator system delignification of flax pulp. Part II: Impact on effluents properties
Fillat Latorre, Úrsula; Roncero Vivero, María Blanca (2009)
Article
Accés obertFlax pulp was bleached by using an enzyme treatment with laccase (L stage) in the presence of HBT as mediator in order to replace chlorine-based pulp bleaching processes which produce toxic organochlorine compounds with ... -
Integrating a xylanase treatment into an industrial-type sequence for eucalyptus kraft pulp bleaching
Fillat Latorre, Úrsula; Roncero Vivero, María Blanca; Sacón, Vera Maria; Bassa, Alexandre (American Chemical Society (ACS), 2012)
Article
Accés restringit per política de l'editorialThe influence of a treatment with two commercial xylanases on pulp and effluents obtained after the bleaching stages in the OXAZDP (O, oxygen stage; X, xylanase treatment; A, acid stage; Z, ozone stage; D, chlorine dioxide ...
