  • Thermostable alpha-galactosidase and methods of use
    Patent number: 6150171
    Abstract: An isolated nucleic acid from the bacterium Thermotoga neapolitana, encoding a thermostable .alpha.-galactosidase is provided. The Thermotoga gene is cloned into a high expression vector to provide large quantities of a purified thermostable .alpha.-galactosidase. The thermostable enzyme is used in high-temperature processing of soy products to remove .alpha.-galactosides.

  • Method for the conversion of a cellulosic substrate to glucose using Microbispora bispora, strain Rutgers P&W
    Patent number: 4628029
    Abstract: A method is described for the enzymatic saccharification of a cellulosic substrate to glucose which utilizes fermentation of the substrate with the cellulase enzyme complex-producing, thermophilic microorganism Microbispora bispora Rutgers P&W and its mutants. The resistance of M. bispora Rutgers P&W cellulase to end-product inhibition enables conversion efficiency superior to that of known cellulase producing microorganisms. Continued enzyme activity at elevated temperatures allows broader applicability of enzyme-catalyzed saccharification than heretofore attained. The microorganism in its purified form incubated on cellulase, and its cellulolytic mutants, are also disclosed.
