title: [A contribution to the recovery of poliomyelitisvirus from digested sewage sludge dependent on pH-value (author's transl)].
abstract: For later investigations on the influence on virus in digested municipal sewage sludge four different methods were tested to recover virus of poliomyelitis from the sludge. The best results were obtained by elution with 3% beef-extract at pH 9, followed by ultrasonic-treatment. The recovery-rate is not significantly influenced by the final concentration of beef-extract. Poliovirus inoculated to anaerobic digested sludge shows a 90% reduction within 7 hours at room-temperature.
