  • PREPARATION OF HOLLOW CELLULOSE VESSELS
    Publication number: 20100042197
    Abstract: The present invention relates to an improved method for the preparation of hollow cellulose vessels produced by a microorganism, and hollow cellulose vessels prepared by this method. The method is characterized by the culturing of the cellulose-producing microorganisms being performed on the outer surface of a hollow carrier, and providing an oxygen containing gas on the inner side of the hollow carrier, the oxygen containing gas having an oxygen level higher than atmospheric oxygen.

  • Recombinant expressing chimeric glucose transporters
    Patent number: 7507574
    Abstract: The present invention provides a modified Saccharomyces yeast which produces significantly lower levels of ethanol than wild-type yeast under aerobic conditions and saccharide concentrations of 2% glucose, and which exhibits a growth rate of at least 30% of the wild-type yeast, preferably containing a chimeric construct of at least 2 saccharide transporters, nucleic acid molecules encoding the chimeras and polypeptides encoded by such sequences, and methods of using the modified yeast for preparing products in the yeast.
