TERMITE SUPEROXIDE DISMUTASES AND GLUTATHIONE PEROXIDASES FOR BIOMASS CONVERSION

摘要

The present disclosure is generally related to enzymes, and to recombinant nucleic acid molecules encoding and/or expressing said enzymes, of the gut of the termite Reticulitermes flavipes. The disclosure further relates to a system combining said enzymes for substantially converting a plant lignocellulose to a fermentable sugar-based product.

主权项

1. A system for producing a fermentable product from a lignified plant material, the system comprising either: (i) the catalytically active domains, or polypeptides comprising said catalytically active domains, of cellulases Cell-1 and β-glu, and further comprising a catalytically active domain of at least one enzyme, wherein said enzyme is a cellulase, an aldo-keto-reductase, a catalase, or a laccase; or (ii) the catalytically active domains, or polypeptides comprising said catalytically active domains of a endo-xylanase, a superoxide dismutase, and a glutathione peroxidase and, optionally, a laccase, and wherein the catalytically active domains, or polypeptides comprising said catalytically active domains, cooperate to provide a fermentable product from a lignified plant material.
