Fungal isolates are useful for wood biopulping, resulting in savings in energy and chemicals. They are also important for the bioconversion of agriculture and forestry products such as improving animal feed, release of simple sugars for ethanol production, and treatment of residual effluents. - Wood from Eucalyptus spp. is being increasingly used for pulp and paper production in South America, where Brazil and Uruguay are the main Kraft pulp producers from Eucalyptus spp. In Uruguay alone, for example, nearly 50% (two hundred thousand hectares) of the forested area designated for industrial purposes consists of Eucalyptus species, mainly E. globulus and E. grandis, with an estimated annual increase of 2.9% for the past 30 years. The screening of native strains of white-rot fungi, with the ability to degrade E. grandis and E. globulus woods, is therefore of particular value. The aim of this work was to test the preferential delignification of E. grandis and E. globulus by 42 native white-rot fungal strains isolated in Argentina, Brazil and Uruguay.
