Abstract: The invention relates to a method for extracting nucleic acids of microorganisms contained in a complex mixture, particularly a food mixture, comprising at least the following steps: the mixture is clarified; the microorganisms are retained on a filtering cartridge; said microorganisms are lysed; the nucleic acids are recovered, concentrated, and purified. The invention also relates to a filtering cartridge and an apparatus used for carrying out the inventive extraction method. Also disclosed is a device for extracting, detecting, and if necessary quantifying the nucleic acids of microorganisms contained in a complex mixture.

Abstract: A formed adsorbent material includes an adsorbent solid phase and a gas phase ensuring transport of the gaseous components right to the adsorbent, being such that the constants for the transport kinetics of the components adsorbable in the gas phase and in the solid phase are in a ratio of between 0.1 and 10 defined for a gas discharge velocity of 0.2 m/s measured on air at 1 bar and 20° C. or in a ratio of between 0.1 and 10, defined for a gas discharge velocity of 0.01 m/s measured on hydrogen at 30 bar and 40° C.
