  • Porphyranases, and use thereof for hydrolyzing polysaccharides
    Patent number: 8759039
    Abstract: The present invention relates to the isolation and to the characterization of two proteins having a novel enzymatic activity, i.e. a porphyranase activity. These proteins are useful for hydrolyzing polysaccharides containing sulfated agaro-colloids and for producing oligo-porphyrans, notably oligo-porphyrans with a defined structure and size.
    Type: Grant
    Filed: July 20, 2010
    Date of Patent: June 24, 2014
    Assignee: Centre National de la Recherche Scientifique (C.N.R.S.)
    Inventors: Jan-Hendrik Hehemann, Gaëlle Correc, Gurvan Michel, Tristan Barbeyron, William Helbert, Mirjam Czjzek
  • METHOD FOR DEPOLYMERISING POLYSACCHARIDES BY MEANS OF MECHANICAL MILLING
    Publication number: 20130032650
    Abstract: A method for controlled reduction of the weight average molar mass of a polysaccharide down to a lower and determined weight average molar mass, which method includes a step for mechanical milling of the polysaccharide by a ball mill, until the polysaccharide having the desired weight average molar mass is obtained.
