    摘要: The present invention relates to DNA constructs that can produce antimicrobial materials efficiently from microorganisms and the preparation method thereof. The present invention also relates to the useful vector for the DNA construct. The DNA construct according to the present invention comprises a first gene coding for entire, a part of or a derivative of purF gene and a second gene coding for antimicrobial peptide. According to the present invention, antimicrobial peptides can be mass-produced by the following steps: preparing an expression vector containing a DNA construct comprising a first gene coding for an entire, a part of or a derivative of purF gene and a second gene coding for antimicrobial peptide; transforming the bacterial host cells with the above-mentioned vector, culturing the transformed cell to express the above-mentioned DNA construct; and recovering the above antimicrobial peptide.

    摘要: The present invention provides a method for mass production of an antimicrobial peptide, which comprises the steps of: constructing a fusion gene containing a first gene encoding a negatively charged acidic peptide having at least two cysteine residues and a second gene encoding a positively charged basic antimicrobial peptide; transforming a host microorganism with an expression vector comprising the fusion gene; cultivating the transformed microorganism to express a fusion peptide containing the acidic peptide and antimicrobial peptide, and, recovering the expressed antimicrobial peptide. In accordance with the present invention, the inhibitory effect of the expressed antimicrobial peptide on the growth of the host microorganism can be dramatically minimized by fusing it with the acidic peptide. Accordingly, antimicrobial peptides can be produced massively from a recombinant microorganism regardless of the kind of the antimicrobial peptides.

    摘要: The present invention relates to a novel ice nucleation active Xanthomonas strain and a bacterial ice nucleator comprising the ice nucleation active microorganism which can be applied for food processing and artificial snow making. The present inventors have screened ice nucleation active microorganisms from leaves of crops and plants, and investigated their ice-nucleation activities. As a result, the inventors discovered that a novel microorganism belonging to Xanthomonas campestris has a superior ice-nucleation activity than those of the conventional ice nucleation active microorganisms. Accordingly, the ice nucleation active microorganism of the invention can be used as a potent bacterial ice nucleator for food processing and artificial snow making.
