[UV-inactivation of microorganisms in water].

Abstract

UV-Inactivation of Escherichia coli, Bacillus subtilis spores, Staphylococcus-Phage A 994, Poliovirus type Mahoney and Rotavirus SA 11 was tested under controlled physical conditions. B. subtilis-spores were found to be the most resistant of these microorganisms, followed by Rotavirus, Bacteriophage and Poliovirus. E. coli required the lowest irradiation dose for inactivation. Causes and meaning of these dose-survival-reactions are discussed.
