Abstract excerpt
The resistance of Euglena gracilis strains Z (wild type) and SM-ZK (chloroplast-deficient mutant) to ionizing radiation was investigated. The colony forming ability of E. gracilis strain Z was higher than that of strain SM-ZK after 60Cogamma-irradiation. For both strains, the resistance of light-grown cells was higher than that of dark-grown cells, suggesting that the light conditions during culture contribute to...
