Comparative study of lignocellulolytic activities of Pleurotus spp. and white rot and brown-rot fungi
1997 - IRG/WP 97-10210
In this work, the in vitro species of Pleurotus (P.eringii, P. cornucopiae and P. ostreatus), from structures of degraded wood have been studied. This degradative activity was compared to those presented by Trametes versicolor (fungus characteristic of white rot) and Gloeophyllum trabeum (fungus representative of brown rot). The activities studied were the following: cellulase, xylanase, pectinase...

Comparative study of the degradative ability of autochthonous and standardized strains of wood decay fungi
1996 - IRG/WP 96-10178
This study is intended to assess the biomass, the extracellular protein production, and the carbohydrate degradating ability of three standarized (Chaetomium globosum, Trametes versicolor and Gloeophyllum trabeum) and six autochthonous wood decay fungi strains, with unknown degradating effects. The carbohydrate sources used were those that are usually found in wood cells (glucose, galactose, manos...

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...

Influence of the nature of the substrate and the method of inoculation on the degradative activity of soft rot fungi
1998 - IRG/WP 98-20133
The European Standard (ENV-807) determines the threshold of effectiveness of wood preservatives against the action of soft rot Ascomycetes fungi. Its application in the treatment of wood used in the hazard class 4 does not always offer repeatable results, which could be expected in an experimental norm. For this reason, in this paper, we have evaluated the diverse variables that might influence t...

Study of the durability of the Maderon® against wood decay fungi and insects
2011 - IRG/WP 11-40548
Many industries produce residues that are not easily degradable. One of these is nut husks which, due to their high level of resistance to biological and environmental degradation, have become an ecological problem. Maderón® is a material invented and patented in Spain employed as an ecological substitute and a modern alternative to certain uses of wood. At present, Maderón® is commercialized ...

Application of nanoparticles of silver and nanoparticles of titanium dioxide in reinforcement of wood and coating for wood in Costa Rica
2015 - IRG/WP 15-40698
Wood is one of the most widely used materials in last 20 years by society in many applications, with a considerable proportion of this material coming from forest plantations. Plantations usually produce timber with reduced strength properties and low natural durability. On the other hand, nanotechnology applications have the potential to increase wood properties. Likewise, nanotechnology cannot o...
