摘要： The invention concerns a method for producing nanocelluloses from a cellulose substrate comprising cellulose fibres, said method comprising the following sequence of steps: - a step of enzymatic treatment of said cellulose substrate, by bringing same into contact with at least one cleaving enzyme, then - a step of mechanical treatment of said cellulose substrate subjected to said step of enzymatic treatment, in order to delaminate said cellulose fibres and obtain said nanocelluloses, characterised in that said 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. The invention also relates to the nanocelluloses obtained according to said method. No figure.

摘要： The invention relates to a method for obtaining an emulsion including an internal hydrophobic phase dispersed in a continuous hydrophilic medium (MIPE) or high (HIPE) internal phase having an internal phase percentage of more than 55%. Said method includes the following steps: a) obtaining an oil-in-water emulsion composition having a hydrophobic phase/hydrophilic phase volumetric ratio of at least 5/95, including a step of incorporating cellulose nanocrystals into said hydrophilic phase and a step of forming the emulsion by dispersing said hydrophobic phase in said hydrophilic phase; and b) obtaining said emulsion having an internal phase percentage of more than 55%, including: b.1) a step of adding an amount of a hydrophobic phase to the emulsion composition obtained in step a), and agitating the resulting mixture; and/or b.2) a step of concentrating the emulsion composition obtained in step a) by removing at least a portion of said hydrophilic phase.

摘要： The present invention relates to a colorimetric device for detecting, in an aqueous solution of interest, hydrolytic enzymatic activity with regard to at least one polymer of interest. This device (1) comprises (i) a substrate (2) and (ii) a transparent detection layer (3) that includes the polymer of interest. The detection layer (3) is adapted to: maintain a first thickness
e after application of the aqueous solution of interest when the latter has no hydrolytic enzymatic activity; and have a second thickness
e' , smaller than the first thickness
e , after application of the aqueous solution of interest when the latter has hydrolytic enzymatic activity. This first thickness
e and/or the second thickness
e' of the transparent detection layer (3) are/is designed to generate a colour by means of an optical interference effect produced by the recombining of the light beams reflected at the interfaces (4, 5) of said detection layer (3).
