Abstract
The composition is obtained by a process in which at least one strain of Trichoderma reesei is brought into contact with a carbonaceous fermentation medium comprising a supply of water-soluble sugars, which consists at least in part of a raw extract of water-soluble pentoses originating from a pretreated lignocellulosic substrate. Application to the hydrolysis of substrates such as deciduous wood, cereal straw and maize stalks.
