  • Electropulsing process for producing proteins
    Publication number: 20040097715
    Abstract: The present invention concerns a process for producing proteins in which a stream of liquid medium comprising at least one yeast, bacterium or mammalian cell undergoes electropulsing, and the proteins that are liberated are recovered. The process comprises an electropulsing step followed by an incubation step.

  • Method for eliminating Legionella from a colonised aqueous flow by electropulsing, a method for treating an aqueous flow by electropulsing, and its application to eliminating Legionella
    Patent number: 6669901
    Abstract: The invention relates to a method for treating an aqueous flow colonised by cells by applying a pulsed electric field, the intensity of the field being less than 1 kV/cm. It also relates to the application of this method to eliminating Legionella and to a method for destroying Legionella.

  • Method for treatment of an aqueous flux by electropulsation of a field parallel to the flow, pulsation chamber and uses thereof
    Patent number: 6623964
    Abstract: The invention concerns a method for treating an aqueous flow colonized by cells with a pulsed electric field applied to a flow, characterized in that the applied field is substantially parallel to the direction of flow and to its application to the transfer of nucleic acids (RNA, DNA, oligonucleotides) into cells, to the transfer of proteins to cells, to the extraction of cytoplasmic macromolecules and molecules contained in the cells, to cell fusion and the production of hybrids and/or to insertion of membrane proteins. It also concerns an electropulsing chamber, a method for destroying cells and a membrane permeabilization method.

  • Method for eliminating protozoa, in particular free living amoebas in a colonised aqueous flow, a method for treating an aqueous flow by electropulsing, and its application to eliminating protozoa
    Publication number: 20030165399
    Abstract: The invention relates to a method for treating an aqueous flow colonised by cells by applying a pulsed electric field, in which a colonised aqueous flow is subjected to an electric field of an intensity of 1 to 30 kV/cm, and to its application to destroying protozoa, in particular free living amoebas. It also concerns a method for destroying protozoa.
