Abstract
L'invention est caractérisée en ce qu'on implante un micro-organisme aérobie tel quel ou une préparation enzymatiquement active qui en dérive, spécialement choisis pour le bois dur en question, en quantité suffisante à l'intérieur ou sur la surface du bois, en vue de son attaque, et on règle la température, l'humidité, la teneur en 02 et la teneur en CO2 en rapport avec le micro-organisme choisi ou la préparation enzymatiquement active qui en dérive, la modification sélective du bois dur étant ainsi réalisée et le procédé étant arrêté de manière convenable.
