  • Recombinant strain and method for producing active pediocin PA-1
    Patent number: 11807856
    Abstract: A recombinant Pichia pastoris strain which is genetically modified for highly expressing pediocin PA-1 and secreted into a medium so that the pediocin PA-1 is easily collected and purified from the culture medium. The obtained pediocin PA-1 has specific antimicrobial activities against Listeria monocytogenes ATCC 13932 and several other bacteria strains.

  • Mixture of cell extract and method for site-directed cloning
    Patent number: 11198879
    Abstract: The present invention provides novel reagents and a cloning procedure based on homologous recombination for the site-directed cloning of a DNA fragment to a vector at designed site(s). The cloning reagents are made of mixture of extracts from at least two different cell types, preferably a mixture made of extracts from wild-type E. coli and S. cerevisiae. Due to the activity of the mixture of cell extracts, recombination occurs between the 3? and 5?-ends of the target DNA and at the ends of linearized vector, which facilitates in-frame construction of expression vectors.
