To exterminate intestinal bacteria in preserved night soil, the temperature affects strongly, but it seemed that the synthetic action of different factor of ph, nutrition, antivirus, bacteriophage etc. would be important.<BR>About the abstracted substance which showed the bactericidal effect against different intestinal bacteria in night soil, the follwing results were reached.<BR>1. It is not solidificated by heating at 100°C, and is not separated by HCI at pH 2, 0.<BR>2. It is not absorbed with the ion exchange resin, Amberlite IRC 50.<BR>3. It is not separated in the alcoholic solution.<BR>4. It passes easily cellopfane dialystic membrane.<BR>5. It is especially effective to Salmonella typhi and Shigella shigae.<BR>6. As a result of qualitative examinations, sugar and amino-acid were found positive.
