Ultraviolet sensitivity gene of Escherichia coli B.
The ultraviolet sensitivity gene of Escherichia coli B was introduced into a K-12 recipient by transduction with phage P1. The uvs gene of E. coli B is cotransducible with the proC locus of K-12, is closely linked to tsx, is not linked to lacZ, and only rarely to purE. The transductants are mucoid, filamentous on irradiation, and show plating-medium response. The order of markers is lacZ proC t...
متن کاملMembrane Modifications in Nutritionally Induced Filamentous Escherichia Coli B
Nutritionally induced filamentous cell forms of Escherichia coli B were examined for their morphological and biochemical lesions. The filamentous forms showed no significant alteration in total DNA concentration, RNA synthesis, ability to form beta-galactosidase in response to isopropylthiogalactoside, or insensitivity to actinomycin D as compared to the normal cell form. The filamentous cells ...
متن کاملAmplified RNase H activity in Escherichia coli B/r increases sensitivity to ultraviolet radiation.
Strains of E. coli B/r transformed with the plasmid pSK760 were found to be sensitized to inactivation by ultraviolet radiation (UV) and to have elevated levels of RNase H activity. Strains transformed with the carrier vector pBR322 or the plasmid pSK762C derived from pSK760 but with an inactivated rnh gene were not sensitized. UV-inactivation data for strains having known defects in DNA repair...
متن کاملPostirradiation responses of ultraviolet irradiated Escherichia coli.
The phenomena of photoreactivation (Jagger, 1958) and dark reactivation (Ellison, Erlanger, and Allen, 1955; Heinmets et al., 1954; Roberts and Aldous, 1949), while raising questions concerning the mechanism of action of ultraviolet irradiation (Zelle and Hollaender, 1955; Kimball, 1957), have also been useful tools for the study of radiation effects on living systems. Many factors which alter ...
متن کاملPhotocatalytic Removal of Escherichia Coli by ZnO Activated by Ultraviolet-C Light from Aqueous Solution
Abstract: Background and objectives: There is a great interest in photocatalytic oxidation of contaminants, using ZnO, in recent years. The main objective of this research was to study photocatalytic disinfection of E. coli bacteria as water microbial pollution index, using nano particles of ZnO and a UV lamp in a batch reactor. Material and Methods: In this study, the contaminated water sample...
