Project description:In the present work, Abortiporus biennis, a white-rot fungus, was studied in regard to its lignocellulolytic enzymatic potential. Secretomics analyses, combined with biochemical methods, were employed to study the enzymatic machinery of the strain, after growth in corn stover cultures and xylose-based defined media. The results revealed the presence of all the necessary enzymatic activities for complete breakdown of the lignocellulosic substrate, while the prominent role of oxidative enzymes in the lignocellulolytic strategy of the strain became evident. Two novel laccases, AbiLac1 and AbiLac2, were isolated from the culture supernatant of this fungus.
