  • Novel antimicrobial bolisin peptides
    Publication number: 20090149391
    Abstract: The invention relates to antibiotically effective peptides which are prepared for medical and commercial use by using biotechnological methods and chemical synthesis. The antibiotically effective peptides can be used in a suitable galenic formulation as medicaments/animal medicaments, food additives or as preservatives for the prevention of microbial contaminations of cosmetics, medical products and requisites.
    Type: Application

  • Bifidogenic peptides
    Patent number: 6849593
    Abstract: Pepetides having bifidogenic properties are obtainable by the process of adding proteases to cow'milk or human milk, followed by incubation, centrifugation, acidification, purification by reverse phase HPLC and cation-exchange HPLC, culturing Bifidobacterium bifidum and E. coli in the presence of collected bifidogenic fractions, and isolation of the peptides having bifidogenic properties, and the isolated peptides can be amidated, acetylated, sulfated, phosphorylated, glycosylated, oxidized, or fragmented and still maintain their bifidogenic properties, and combination peptides having bifidogenic properties are obtainable by chemically bonding the peptides having bifidogenic properties, the amidated, acetylated, sulfated, phosphorylated, glycosylated, oxidized, or fragmented peptides having bifidogenic properties, or combinations thereof.
