Key Words Effects of sunlight and predacious microorganisms on survival of enteric bacteria in sewage water
Abstract The disinfection effects of sunlight and predacious microorganisms on enteric of Escherichia coli and Proteus vulgaris were examined in sewage water at 22 to 26℃. The test prganisms were disinfected by 4 to 5 logs during 6-hour a day exposure to sunlight for seven days. The effect was proportional to the light intensity and was proved to be due to the action of the visible light of short wavelength which can transmit the soft glass of a flask glass. The predacious microorganisms decreased the test organisms by about 3 to 4 logs during 7 days. The complex actions of sunlight and predacious microorganisms were variable depending upon the test organisms, but the total effects of those environmental factors were yet completely understood.
