Abstract

Procédé efficace de dégradation de la lignocellulose. Il consiste à fournir un substrat composé de lignocellulose humidifié avec une solution minérale nutritive dont le pH est compris entre 4 et 5, ce substrat étant composé d'environ 10 %, à 80 % en poids environ de solides lignocellulosiques par rapport à la quantité totale de solides lignocellulosiques et de solution nutritive, à inoculer ce substrat avec Chrysosporium pruinosum, à maintenir le substrat inoculé à une température comprise entre 20 et 45 degrés C environ pour faire croître Chrysosporium pruinosum qui produit des systèmes enzymatiques qui dégradent la lignocellulose, et à laisser cette moisissure croître à cette température jusqu'à ce qu'au moins une quantité significative de lignocellulose air été dégradée. Application à la fabrication de sucre, d'aliments pour bétail, etc.Efficient process for degrading lignocellulose. It consists in providing a substrate composed of lignocellulose moistened with a mineral nutrient solution whose pH is between 4 and 5, this substrate being composed of about 10%, to about 80% by weight of lignocellulosic solids relative to the total quantity lignocellulosic solids and nutrient solution, to inoculate this substrate with Chrysosporium pruinosum, to maintain the inoculated substrate at a temperature of between 20 and 45 degrees C approximately to grow Chrysosporium pruinosum which produces enzyme systems that degrade lignocellulose, and to leave this mold will grow at this temperature until at least a significant amount of lignocellulose has been broken down. Application to the manufacture of sugar, animal feed, etc.
