Penicillium Ochrochloron RLS11 Secretome Containing Carbohydrate-Active Enzymes Improves Commercial Enzyme Mixtures During Sugarcane Straw Saccharification.

Filamentous fungi are prolific producers of carbohydrate-active enzymes (CAZymes) and important agents that carry out plant cell wall degradation in natural environments. The number of fungal species is frequently reported in the millions range, with a huge diversity and genetic variability, reflecting on a vast repertoire of CAZymes that these organisms can produce. In this study, we evaluated the ability of previously selected ascomycete and basidiomycete fungi to produce plant cell wall-degrading enzyme (PCWDE) activities and the potential of the culture supernatants to increase the efficiency of the Cellic® CTec2/HTec2 for steam-exploded sugarcane straw saccharification.
