Abstract (en)

[origin: WO2007143971A2] In the method for inactivating viruses and/or bacteria in liquid media, in particular in blood plasma and preserved serum, the medium is irradiated under a protective gas with low frequency ultrasound. The medium is irradiated with a power density of the ultrasound which is such that hard cavitation occurs, wherein cavitation bubbles produced in the medium implode in such a way that shock waves are generated which inactivate the viruses and/or bacteria. The frequency of the ultrasound is selected in the range of 15 kHz to 40 kHz. Preferably, the medium is poured into a container made of a material which lets through gas but not liquid. An additional treatment with UV light is advantageous.
