Radiation damage to K+ permeability of an unsaturated fatty acid auxotroph of E. coli grown with oleate or linolenate was investigated at different temperatures. A remarkable effect of radiation was observed at 0 degrees C with cells that had been grown with linolenate at 42 degrees C. This indicates that, besides protein, membrane lipids at least are involved in the radiation damage. The damage also seems to be affected by the fluidity of membrane lipids.
