  • Cloning of cellulase genes from acidothermus cellulolyticus
    Patent number: 5514584
    Abstract: A process is described for moving fragments that code for cellulase activity from the genome of A. cellulolyticus to several plasmid vectors and the subsequent expression of active cellulase acitivty in E. coli.
    Type: Grant
    Filed: June 27, 1994
    Date of Patent: May 7, 1996
    Assignee: Midwest Research Institute
    Inventors: Stanley M. Lastick, deceased, Melvin P. Tucker, Karel Grohmann
  • Combined enzyme mediated fermentation of cellulous and xylose to ethanol by Schizosaccharoyces pombe, cellulase, .beta.-glucosidase, and xylose isomerase
    Patent number: 5372939
    Abstract: A process for producing ethanol from mixed sugar streams from pretreated biomass comprising xylose and cellulose using enzymes to convert these substrates to fermentable sugars; selecting and isolating a yeast Schizosaccharomyces pombe ATCC No. 2476, having the ability to ferment these sugars as they are being formed to produce ethanol; loading the substrates with the fermentation mix composed of yeast, enzymes and substrates; fermenting the loaded substrates and enzymes under anaerobic conditions at a pH range of between about 5.0 to about 6.0 and at a temperature range of between about 35.degree. C. to about 40.degree. C. until the fermentation is completed, the xylose being isomerized to xylulose, the cellulose being converted to glucose, and these sugars being concurrently converted to ethanol by yeast through means of the anaerobic fermentation; and recovering the ethanol.
