  • Publication number: 20190002846
    Abstract: The present invention relates to fungal enzymes, more in particular of polyphenoloxidases (PPOs), and is based on a newly discovered enzymatic activity of a class of PPOs, i.e. de-methylation of R-substituted mono- or di-methoxyphenolsuch as present in lignin, lignin derived compounds and/or in lignocellulosic biomass. This newly discovered enzymatic activity renders these enzymes highly suitable for a plethora of applications in industry. Provided herein are methods of demethylation, processes to increase the reactivity of lignin or lignin-comprising biomass, processes of conversion lignin or lignin comprising biomass to value added products, processes for degrading and/or modifying (hemi-)cellulose in a hemicellulose-comprising substrate, and expression vectors, host cells and liquids, pastes or solid formulations and compositions for use in the demethylation method of the invention.

  • Patent number: 10160823
    Abstract: A lignin-phenol-formaldehyde resin, which is obtained by polycondensation of formaldehyde, phenol and lignin in the presence of a basic or acidic catalyst, is characterized in that the lignin is a lignin that is not chemically modified at the available functional groups. This lignin has a low molecular mass and includes available functional groups chosen from the group including aliphatic hydroxyls and phenolic hydroxyls. The degree of substitution by weight of phenol with the lignin is between 50% and 60%. The weight proportion of the lignin and of phenol in the resin is equal to the weight proportion of phenol in a lignin-free phenol-formaldehyde (PF) resin.

  • Publication number: 20170137847
    Abstract: A process for producing ethanol includes steps of pre-treatment of the lignocellulosic vegetable raw material, including the steps consisting in destructuring the lignocellulosic vegetable raw material, then in separating, on the one hand, the cellulose (C6) capable of then being hydrolysed (and fermented for the production of ethanol) and, on the other hand, the hemicelluloses capable of then being hydrolysed and the lignins. The hydrolysis of the cellulose and of the hemicelluloses is then carried out in a sequenced manner according to the following steps consisting in: i) beginning the enzymatic hydrolysis of the cellulose by at least one enzyme for a first period with a view to obtaining an intermediate hydrolysate; ii) adding hemicelluloses to the intermediate hydrolysate; iii) continuing the enzymatic hydrolysis of the mixture until a final hydrolysate is obtained at the end of a total period of enzymatic hydrolysis.

  • Patent number: 9518274
    Abstract: A process for producing bioethanol includes the steps of pretreatment (consisting in destructuring the lignocellulosic vegetable raw material by placing it in the presence of a mixture containing formic acid, acetic acid and water, then in separating cellulose), of enzymatic hydrolysis and of alcoholic fermentation, characterized in that it includes, prior to the enzymatic hydrolysis, a step of partial elimination of the lignins so as to obtain a residual overall level of lignins (T), expressed as percentage by weight, which is non-zero and which is included in a range determined by a lower limit, and an upper limit Bsup, respectively equal to 0.30% and 4%. In order to obtain conditions of acidification before the enzymatic hydrolysis step, the process includes a step for re-acidification of the mixture, which is carried out with an acid, or of a mixture of acids, of determined pKa, and preferably with weak organic.
