  • 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: 20200182787
    Abstract: A process for detecting the sensitivity of one or more polymers and/or of one or more mixtures of polymers to a compound, including the steps of exposing a plurality of individualized micro-deposits including the polymer(s) and/or the mixture(s) of polymers to the compound, and detecting, by interferometry, a variation in appearance of an assembly of micro-deposits exposed to the compound and or a variation in the dimensions and/or refractive index of at least one of the micro-deposits exposed to the compound, linked to an interaction between the polymer(s) and or the mixture(s) of polymers and the compound.

  • Publication number: 20200157591
    Abstract: Celluloses, notably nanocelluloses, and more particularly processes for manufacturing cellulose fibers and for defibrillating cellulose-based substrates. Most particularly, processes for defibrillating cellulose-based substrates and manufacturing celluloses, in particular nanocelluloses (NC), using a new family of fungal lytic polysaccharide monooxygenases (LPMOs).
