Characterization of TS-mutants of cyanophage N-1 by their inactivation by physical and chemical agents.

Abstract excerpt

The effect of temperature, ultraviolet (UV) light and ethylenediaminetetraacetic acid (EDTA) on the stability of cyanophage N-1, infecting the cyanobacterium Nostoc muscorum was studied. Complete inactivation of the phage occurred at 60 degrees C in 6 mins. All the temperature-sensitive (ts) mutants exhibited faster inactivation at 50 degrees C than the wild type. UV light readily inactivated the particles of the...
