  • Kluyveromyces lactis yeast strain and methods for the production of sugars, ethanol, beta-galactosidase and biomass
    Patent number: 9279135
    Abstract: A Kluyveromyces lactis yeast strain comprising the sequence identified by SEQ ID NO: 1, and methods for the production of sugars (glucose and galactose), ethanol, ?-galactosidase and biomass is provided, in which the Kluyveromyces lactis yeast strain is cultured in the presence of a lactose-containing medium. The lactose-containing medium may be milk, whey, whey resulting from the preparation of butter, whey resulting after casein precipitation, milk permeate, whey permeate, acid whey and YPL culture medium.
    Type: Grant

  • STRAINS OF S.CEREVISIAE CAPABLE OF GROWING IN MEDIA WITH MELIBIOSE, STACHYOSE AND RAFFINOSE
    Publication number: 20130273602
    Abstract: The invention relates to strains of S. cerevisiae capable of secreting ?-galactosidase into culture medium, as well as to methods for obtaining ?-galactosidase using said strains and methods for producing biomass and bioethanol by means of culturing said strains in media rich in galactose. In another aspect, the invention provides methods for expressing recombinant proteins using a composition rich in galactose as a culture medium for the microorganisms producing said protein.

  • OPTIMIZED METHOD FOR OBTAINING ACE ACTIVITY INHIBITORY PEPTIDES FROM WHEY, ACE INHIBITORY PEPTIDES AND FOOD COMPRISING THEM
    Publication number: 20120322745
    Abstract: An optimized method for obtaining ACE activity inhibitory peptides includes the steps of whey ultrafiltration for obtaining a whey concentrate, enzymatic hydrolysis, hydrolysate ultrafiltration and inhibitory peptide separation. The method includes selecting and adding a mixture having suitable proportion and amount of two microbial proteases and having complementary action to the whey concentrate for the hydrolysis thereof in order to obtain peptides with an ACE inhibition percentage greater than 70% and an IC50 index of 30 to 100 ?g/ml.
