The use of a material based on lignocellulose materials, particularly a piece of wood or sawdust, subjected to a process for chemically treating said lignocellulose materials with a chemical agent comprising hydrocarbon chains, which agent is selected from mixed carboxylic anhydrides and suitable for grafting a plurality of hydrocarbon chains onto said materials by covalent bonding, to give a material that controls or prevents the development of microorganisms such as fungi and mould that can damage said lignocellulose materials.
Utilisation d'un matériau à base de matières lignocellulosiques, notamment une pièce de bois ou de la sciure de bois, soumis à un procédé de traitement chimique desdites matières lignocellulosiques consistant à soumettre lesdites matières à un traitement par un agent chimique comportant des chaînes hydrocarbonées, cet agent étant choisi parmi les anhydrides carboxyliques mixtes, ledit agent étant adapté pour assurer un greffage par liaison covalente d'une pluralité de chaînes hydrocarbonées sur lesdites matières, comme matériau diminuant voire empêchant le développement des micro-organismes tels que champignons, moisissures susceptibles de dégrader lesdites matières lignocellulosiques.
