title: Killing of Bacillus subtilis spores by a modified Fenton reagent containing CuCl2 and ascorbic acid.
abstract: Bacillus subtilis spores were killed by CuCl(2)-ascorbic acid, chloride ions were essential for killing of spores, and spores with defective coats were killed more rapidly. CuCl(2)-ascorbic acid did not damage spore DNA, and spores killed by this reagent initiated germination. However, spores killed by CuCl(2)-ascorbic acid may have damage to their inner membrane.
