Tóm tắt

The lag phase lengthenings recorded for the proliferation ofEscherichia coli cultured in the presence of starch extracts irradiated with cobalt 60 reflect the bactericidal power of radiolysis products. The toxic effect increases with moisture content and esterification of certain hydroxyl functions of the starch, but does not vary after lipid extraction. Washing the starch before irradiation decreases lethality but lengthens the lag phase.
