  • Use of psychrophilic anaerobic digestion in sequencing batch reactor for degradation of prions
    Patent number: 8486688
    Abstract: The use or process of use of a sequencing batch reactor for eliminating prion in specified risk materials and for measuring the efficacy of a sequencing batch reactor to degrade prior proteins in specified risk materials are disclosed. The specified risk material is fed to a sequencing batch reactor containing a layer of acclimatized anaerobic sludge, and the specified risk material reacts with the sludge at a temperature below 25° C. so as to allow degradation of the prion protein.
