Abstract
The present invention describes the use of a genetically improved Trichoderma reesei strain allowing to limit microbiological contaminations during an industrial process. The genetic strain improvement allows the latter to overexpress an extracellular protein having known antimicrobial properties and compatible with the secretory system of strains of fungi such as Trichoderma reesei. This modified strain can be used to produce the cellulolytic and/or hemicellulolytic enzymes used in a method of producing ethanol from cellulosic or lignocellulosic materials referred to as “second generation” materials.
