TEMPORARY RADIOSTABILITY IN EXTRACELLULAR BACTERIOPHAGES AFTER TRAPPING OF MOLECULES OF THE CYSTEINE-CYSTEAMINE GROUP
Journal Article
·
· Intern. J. Radiation Biol.
Ten different strains of bacteriophages were checked for a new phenomenon tentatively designated as phage-SH complex. The phages were incubated in nutrient broth solution to which 0.5 M cysteine or cysteamine was added. The x irradiation, however, was performed with the phages in an anoxic medium in which the sulphydryl concentration was reduced below that concentration sufficient for protection. It was observed that some phages are able to acquire a temporary radioresistance. The effect of oxygen and of an SH-blocking compound on the phage-SH complex was investigated and related to phage structure. The protective mechanism is discussed in the light of current hypotheses.
