Abstract

Peptides (MW < 5 kDa) produced by 57 cellulolytic fungi can form free radicals. Scanning tunneling microscopy (STM) and IR spectroscopy showed that the peptide produced by Trichoderma pseudokoningii can break the hydrogen bond network of cellulose. The synergic action of these peptides and cellulases increased production of reducing sugars during degradation of native cellulose.
