[Behavior of some microorganisms cultivated in the presence of irradiated maize starch].
The bactericidal effect of water soluble radiolysis products of Maize starch on Escherichia coli cultures declines when the initial population grows. This toxicity varies with the culture environment and the bacterial species: Bacillus subtilis, Lactobacillus plantarum, Streptococcus faecalis, Enterobacter sp. Moreover, for the eucaryote cell Saccharomyces cerevisiae, wild strain or muting "small colonies", only the generating time is altered by the active parts of radiolysis products. The results are analysed with regard to the hypothesis that the hydrogen peroxide is responsible for this toxicity.
