BIOCONVERSION OF LIGNOCELLULOSIC MATERIALS BY FUNGAL “ENZYME COCKTAIL” WITH THE CONTRIBUTION OF A GLYCOSIDE HYDROLASE FROM XYLARIA POLYMORPHA TO RELEASE CARBOHYDRATES AND BIOMETHANOL

Abstract. The multifunctional GH78 glycoside hydrolase from the soft rot ascomycete Xylaria polymorpha (XpoGH78) catalyzed conversion of different lignocellulosic materials to release carbohydrates and biomethanol. disintegrating effect enzymatic lignocellulose treatment can be significantly improved by using kinds hydrolases a phenol oxidase. Thus, rape straw meal XpoGH78 could optimized in presence accessory enzymes i.e. cellulases, xylanases and/or laccase. Synergistic also resulted 17.3 mg total (e.g. arabinose, galactose, glucose, mannose, xylose) per gram substrate after incubating for 72 hrs. In addition, with led marginal biomethanol approx. 17 µg g-1 270 cooperation above enzymes.
