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.
About the abstracted substance which showed the bactericidal effect against different intestinal bacteria in night soil, the follwing results were reached.
1. It is not solidificated by heating at 100°C, and is not separated by HCI at pH 2, 0.
2. It is not absorbed with the ion exchange resin, Amberlite IRC 50.
3. It is not separated in the alcoholic solution.
4. It passes easily cellopfane dialystic membrane.
5. It is especially effective to Salmonella typhi and Shigella shigae.
6. As a result of qualitative examinations, sugar and amino-acid were found positive.
