Abstract: A method for membrane permeabilization of biological cells contained in a product is disclosed. According to one aspect, the method is applied in a treatment device including at least one treatment chamber emitting a pulsed electric field. According to another aspect, the method includes supplying the treatment device with a product including biological cells at a predetermined supply flow rate from a supply unit, introducing the product including the biological cells into the treatment chamber at an introduction flow rate, treating the product introduced into the chamber with a pulsed electric field, and reintroducing the treated product, at a predetermined feedback flow rate at a point that is downstream from the supply unit. According to some aspects, the introduction flow rate includes the feedback flow rate and the supply flow rate.

Abstract: Process for the treatment of cork or a cork-based material particularly with a view towards extracting contaminating organic compounds, in which said cork or said cork-based material is put into contact with a dense fluid under pressure at a temperature of from 10 to 120° C. and at a pressure of from 10 to 600 bars. Manufacturing installation for parts made of cork or a cork-based material, such as bottle corks, comprising an installation for treatment or extraction by putting the said cork or the said material into contact with a dense fluid under pressure.
