  • Fermentation processes using amylolytic enzyme producing microorganisms
    Patent number: 5151354
    Abstract: This invention provides a method for producing amylolytic enzymes by culturing a microorganism, having received as a result of recombinant DNA technology DNA sequences from a donor yeast comprising the coding sequences for the amylolytic enzymes wherein the host microorganism is capable of expressing said amylolytic enzymes. Furthermore, this invention provides microorganisms genetically engineered as to being able to produce and express the amylolytic enzymes, a vector containing the DNA sequences, coding for the amylolytic enzymes and the respective DNA sequences. The said host microorganisms are useful in the production of biomass and many fermentation processes, preferably in the production of special beers.
