Biodegration of treated wood waste by native fungal communities of tropical soil in French Guiana
2012 - IRG/WP 12-50285
Woods have been protected with fungicides for a long time, and the effects of these fungicides on soil after being leached into the ground have turned out to be a true environmental issue. It is in this perspective that we are proposing to study fungal communities of these contaminated woods in a purpose of bioremediation. Most of precedent studies have focused on ability of some Basidiomycetes an...
