Title: The influence of some sulphydryl compounds on γ-ray-induced inactivation and reversion to prototrophy in E. coli B fil- citrul-
Abstract: A study was made of the influence of cysteamine (β-mercaptoethylamine), S,2-aminoethylisothiourea, monothioglycol (β-mercaptoethanol) and cysteine on inactivation and mutation induction in Escherichia coli B fil- citrul- irradiated in nitrogen with 60Co γ-rays. All the compounds afforded protection against inactivation, but when they were added immediately before irradiation no protection was observed below about 10 krad. After 20 min pre-irradiation incubation with the compounds only cysteamine showed this effect. All the compounds appeared to protect against inactivation and against mutation induction to the same extent.
