[Spectrum of formation of photo- and non-photoreactivated damage in E. coli cells irradiated with UV light (250-334 nm)].
A relative contribution of photoreactivated (modified by visible light) and non-photoreactivated (modified by temperature) damages to UV-irradiated (250-334 nm) E. coli B cells was estimated. The contribution of damages modified by temperature to a lethal effect of UV-radiation was invariable within the range from 250 to 334 nm. The photoreactivation of E. coli B cells was also independent of lambda-inactivating UV-light within 250-313 nm, and its value exceeded that of the wild-type E. coli WP2 which did not vary by the mode of UV-damages repair. Moreover, in contrast to E. coli B. cells, the value of the photoreactivation of E. coli WP2 decreased, as lambda-inactivating UV-light increased from 250 to 313 nm.
