  • Patent number: 11332600
    Abstract: Disclosed is a method for producing nanocelluloses from a cellulose substrate including cellulose fibers, the method including the following sequence of steps: —a step of enzymatic treatment of the cellulose substrate, by bringing same into contact with at least one cleaving enzyme, then—a step of mechanical treatment of the cellulose substrate subjected to the step of enzymatic treatment, in order to delaminate the cellulose fibres and obtain the nanocelluloses. The at least one cleaving enzyme is chosen from the enzymes belonging to the family of lytic polysaccharide monooxygenases (LPMOs) capable of achieving cleavage in the presence of an electron donor. Also disclosed are the nanocelluloses obtained according to the method.

  • Publication number: 20210171993
    Abstract: The invention relates to a polysaccaride-oxidizing composition comprising a polysaccaride-oxidizing enzyme wherein, when the said polysaccharide-oxidizing enzyme is compared to the reference polypeptide of SEQ ID NO. 1 as described in the specification by using the BLAST-P comparison method, (i) the said polysaccaride-oxidizing enzyme possesses an amino acid identify of 20% or more with the said reference polypeptide and (ii) the BLAST-P comparison method results in an E-value of 10 e?3 or less.
