Abstract
The in vitro effect of ascorbic acid (AsA) on new phages S1 and S2 was investigated. AsA inactiveted the S-phages at 10^<-3>M order. The reaction mechanism of the inactivation of S-phages by AsA was investigated. The findings indicate that free radical mechanism is involved in the inactivation and reactive oxygen species are responsible for the inactivation. The present data, together with the findings reported so far, confirm that the phage-inactivating activity of AsA is a universally acceptable phenomenon in all the phages.
