  • Ethanol production in
    Patent number: 8097460
    Abstract: The present invention relates to the production of ethanol as a product of bacterial fermentation. In particular this invention relates to a novel method of gene inactivation and gene expression based upon homologous recombination. The method is particularly useful in connection with species of Bacillus such as B. stereothermophilus, B. calvodelox, B. caldotenax, B. thermoglucosidasius, B. coagulans, B. licheniformis, B. thermodenitrificans, and B. caldolyticus.

  • Ethanol production
    Patent number: 7691620
    Abstract: Production of ethanol in a thermophilic bacterium can be achieved by transformation of the bacterium with a heterologous gene encoding pyruvate decarboxylase. The bacterium comprises native alcohol dehydrogenase function and does not comprise a gene encoding a functional lactate dehydrogenase. The bacterium may be grown at elevated temperatures to allow the ethanol to be conveniently removed in a vaporized form from the fermentation medium. Traditional mesophilic microorganisms are incapable of growth at the envisioned elevated temperatures.

  • Modification of bacteria
    Patent number: 6664076
    Abstract: Sporulation-deficient variants of thermophilic, facultatively anaerobic, Gram-positive bacteria can be generated using a plasmid transformation system based on a novel method of in vivo methylation. Such bacteria exhibit improved ethanol production-related characteristics.
