| dc.description.abstract | Wood is one of the most environmentally friendly materials because it is supposed to be ecological. However, chemicals are often used for its preservation against xylophagous organisms that render it unfit for use. Most of these molecules are nowadays proscribed and the rest of the other products are being banned by several international health organizations. Fungi that attack wood are multiple and specifically degrade the wood of different species. The Aleppo pine is a very popular species in Algeria. Its wood is used in many areas. The fungal flora that attacks this wood has been isolated and purified using the Sabouraud isolation medium. Three fungal isolates were selected in this study. The identification of these isolates by in-depth study of the cultural, macroscopic and microscopic colony characteristics made it possible to identify these microorganisms. These are Trichoderma sp, Trametes sp, and Rhizopus sp. The genera Trichoderma and Rhizopus are responsible for coloring the wood. The genus Trametes is the agent of the white rot of wood. In a second study, we tried to valorize treated wood waste. The cultivation of the three fungi isolated from dead Aleppo pine wood was conducted on two types of wood trituration. The results clearly show that these fungi can grow on these wastes, with a preference for fine sawdust than coarse wood chips. We have also shown that sawdust must be sterilized before use because it can carry other fungi. This interesting result shows that these very cheap wood by-products can replace the expensive substrates used in the various industrial fermentations. | |
