Enzymatic hydrolysis of pre-treated lignocellulose with Penicillium verruculosum cellulases
TL;DR: In this article, an alternative enzyme complex from Penicillium verruculosum was used for pre-treatment of lignocellulosic materials, which increased the initial rate of enzymatic hydrolysis.

Enzymatische Depolymerisation von Lignin mittels immobilisierter Laccase
TL;DR: The aim of the work was to provide access to this class of compounds by means of depolymerising lignin, and Laccase immobilisates turned to be particular efficient biocatalysts for this purpose.
