Cette étude rend compte de la production, de la purification et de l’application de cellulases issues de Trichoderma viride, obtenues par une technique de fermentation liquide en culture statique utilisant de la cellulose microcristalline et des déchets peu coûteux et facilement disponibles comme substrat de croissance. Trichoderma viride a été cultivé dans un milieu de fermentation à base de cellulose, dans des conditions de croissance préalablement optimisées. La cellulase a été purifiée par rapport à l’extrait enzymatique brut à l’aide d’une précipitation au sulfate d’ammonium, d’une dialyse et d’une chromatographie sur colonne d’échange d’ions. La cellulase purifiée s’est avérée compatible avec quatre marques locales de lessive, ce qui suggère son potentiel en tant qu’additif détergent permettant d’améliorer le lavage ; on en conclut donc qu’elle pourrait s’avérer utile à des fins industrielles, en particulier dans l’industrie des détergents et de la lessive. L’enzyme cellulase purifiée a également été utilisée comme alternative pour dégrader les déchets (épluchures de pommes de terre) en vue de la production d’alcool, d’acides organiques, etc.
