The effect of a chelator mediated fenton system on activation of TMP fibres and decolorization of synthesized dyes
2004 - IRG/WP 04-50223
The purpose of this work is to improve our current knowledge of the non-enzymatic mechanisms involved in the brown rot degradation of wood, but also to study the potential applications of a chelator-mediated Fenton system in activation of wood fibers and decolorization of synthesized dyes. In this work, Electron Spin Resonance (ESR) spin-trapping techniques were used to study the generation of hyd...

An alternative method for the determination of lignocellulolytic enzymatic activities of white rot fungi
1998 - IRG/WP 98-10261
Some lignocellulolytic activities of wood decay fungi can be evaluated in an indirect way through the study of the decolorization that white rot fungi produces in culture media in the presence of dyes. In this assay, ten dyes were selected, which were added in concentrations of 0.00 1% - 0.003% (P/V) to four-day cultures of Trametes versicolor containing 1% of beech sawdust in a basal salt medium...

Evaluation of mark-release-recapture dyes for Reticulitermes grassei (Clément) (Isoptera: Rhinotermitidae)
2004 - IRG/WP 04-20305
To enumerate foraging territories of termite populations, mark-release-recapture (MRR) appears a more satisfactory method than destructive sampling. Marking of termites has been pioneered by the use of ingested dyes and, accordingly,six candiate dyes were evaluated at several concentrations in Reticulitermes grassei (Clément) workers. Only two of the dyes, neutral red and nile blue A provided co...

Stained wood: The identification of natural dyes and mordants in wooden works of art
2010 - IRG/WP 10-20434
On the basis of current knowledge only natural-colored wood species crafted to veneers were used for the decorative design of furniture and wooden interior in classical antiquity.First applications of artificially stained wood can be dated to the late Middle Ages. In the Renaissance wooden works of art were manufactured by using intarsia of natural-colored, fungus-stained and artificially stained ...
