C.YR 1979 T1 The Effect of Transition Metal Ions on the Resistance of Bacterial Spores to Hydrogen Peroxide and to Heat JF Microbiology, VO 112 IS 2 SP 225 OP 233 DO https://doi.org/10.1099/00221287-112-2-225 PB Microbiology Society, SN 1465-2080, AB SUMMARY: The presence of 10 μm-Cu2+ increased the lethal effect of hydrogen peroxide on spores of Clostridium bifermentans but not on those of Clostridium sporogenes PA 3679, Clostridium perfringens, Bacillus cereus or Bacillus subtilis var. niger. Cu2+ at 100 μm. also increased the lethal effect of heat on spores of C. bifermentans but not on those of B. subtilis var. niger. The rate and extent of Cu2+ uptake by spores of C. bifermentans and B. subtilis var. niger were similar, but examination of unstained sections of spores by electron microscopy suggested that Cu2+ is bound by the protoplasts of spores of C. bifermentans but not of B. subtilis var. niger., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-112-2-225
