Treatment of wood chips by a lignin degrading white-rot fungus combined with mechanical pulping is a process known as biopulping or biomechanical pulping. The process has proven its potential in large studies in the USA and is now under commercalization .Biopulping combined with chemical pulping, i.e.
Lignin is a heterogeneous, phenolic and polydisperse biopolymer which resists degradation due to its aromatic and highly branched structure. Lignin is the most abundant renewable source of aromatic molecules on earth.
The valorization of lignin could therefore provide a sustainable alternative to petroleum refineries for the production of valuable aromatic : Stefan Schoenherr, Mehrdad Ebrahimi, Peter Czermak.
A method for producing paper pulp for use in the making of paper from eucalyptus wood chips. The method comprises inoculating wood chips with white rot fungi, fermenting the wood chips so as to cause a propagation of the fungus through the wood chips and allowing the fungus to modify the lignin, and pulping the degraded wood chips by a kraft by: 9.

Morris M. Gibbs. This suggests that the fungi that react positively with these dyes present a wider range of ligninolytic enzymes, making them potential candidates for the treatment of effluents from the textile industry, biopulping, kraft pulp bleaching or the bioremediation of organopollutants, among others (Freitag and Morrell, ; Okino et al., The book provides the most up-to-date information available on various biotechnological processes useful in the pulp and paper industry.
The first edition was published incovering a specific biotechnological process or technique, discussing the advantages, limitations, and prospects of the most important and popular processes used in the industry.

A cellulase and a xylanase enzyme preparation were assessed for their potential to enhance the fiber characteristics of both mechanical and kraft pulps derived from Douglas-fir wood chips.
The effects of cellulase treatments on the pulp properties were dependent on enzyme dosage and resulted in improvements in handsheet density and smoothness, pulp freeness and fiber coarseness. However, Author: Shawn Denton Mansfield.

Waste treatment of kraft effluents by white-rot fungi. SciTech Connect. Kondo, R. The residual lignin in unbleached kraft pulp is commonly removed to afford a fully bleached pulp through a multi-stage bleaching process consisting of chlorination and alkaline-extraction stages.
While for the variation of the thickness of the chip, the lowest amount of selulose and the highest amount of degradation of lignin is find at 3 mm. Keyword: Kraft process, Biopulping, Trametes Versicolor fungi sp, of lignin.-selulose, degradation.
Similar stabilization of Lip by calcium ions was also observed . Distribution of Lip among white-rot fungi seems to be restricted to certain consortia of white-rot fungi and it may serve to detect the Lip activity among others with low pH value around for further survey of Lip activities [21,45,46].
The Reaction Mechanism : Introduction. Laccase (benzenediol:oxygen oxidoreductase; p-diphenol oxidase EC ), a blue multi copper oxidase (MCO), was first discovered by Yoshida () 1 in the latex of the Chinese or Japanese lacquer trees (Rhus sp.). In plant these enzymes seem to be involved in lignification, in wound healing as part of an herbivore or pathogen defense response, and in iron metabolism.

Treatment of bleach mill effluents using the white-rot fungi is promising and offers the option to expand the range of pollutants that cannot be biodegraded by the prokaryotes (bacteria). White-rot fungal remediation may be particularly suited for those recalcitrant compounds for which bioavailability and toxicity are the key issues.
One of the early reports indicated that lignin-degrading white rot fungi, as exemplified by Phanerochaete chrysosporium, can degrade an extremely diverse group of environmental pollutants (Bumpus et al., ).
Since then, there has been intense worldwide research to unravel the. Treating wood with white rot fungi or enzymes derived from decay fiingi is the basis of the experimental biopulping and some biobleaching methods.

White-Rot Fungi. Due to their ability to degrade lignin as well as polysaccharides found in cellulose and hemicellulose, white-rot fungi have the potential not only to act as a biological pre-treatment but also to degrade all the major components of lignocellulose to yield a valuable product.
In the study of lignin peroxidase isozyme H8 from white-rot fungi Phanerochaete chrysosporium (LiPH8), W site was revealed to make the covalent coupling with one moiety of monolignolic radical (guaiacol radical) by LC-MS/MS analysis.
Hypothetical electron-relay containing W residue was newly suggested based on the observation of repressed.(Advances in Biochemical Engineering Biotechnology) K.E.L.
