Manganese Peroxidase, Produced by Trametes versicolor during Pulp Bleaching, Demethylates and Delignifies Kraft Pulp.
Previous work has shown that Trametes (Coriolus) versicolor bleaches kraft pulp brownstock with the concomitant release of methanol. In this work, the fungus is shown to produce both laccase and manganese peroxidase (MnP) but not lignin peroxidase during pulp bleaching. MnP production was enhanced by the presence of pulp and/or Mn(II) ions. The maximum level of secreted MnP was coincident with ...
متن کاملEnzymes Improve Ecf Bleaching of Pulp
The delignification efficiency of different laccase enzymes was examined on the eucalyptus Kraft pulp. The laccase enzyme from Trametes versicolor showing the highest delignification efficiency was selected and used in the elemental chlorine-free bleaching sequence for improving the pulp bleachability. An appreciable reduction in chlorine dioxide consumption was also obtained. Further reduction...
متن کاملUse of Enzymes in Deinked Pulp Bleaching
To comply with government’s environmental policies and to satisfy the requests of the consumers, recycling of waste paper is essential for reducing the consumption of virgin fibers in pulp and paper industry. However, the poor optical properties of recycled fibers restrict their use in value-added papers. Enzymes, such as lipase and laccase, represent an interesting alternative. The detachment ...

متن کاملRagauskas Overview of Hexenurinic Acids on Pulp Bleaching Influence of Hexenuronic Acids on Kraft Bleaching
Over the past ten years there has been a research renaissance in hemicellulose chemistry as it applies to pulping and bleaching operations. Researchers have identified hemicelluloses as an important component influencing pulp yields, strength properties, and pulp bleachability. This report summarizes the research activities undertaken at IPST in the dues funded research consortium (DFRC) projec...
