細菌胞子の段階殺菌法における防腐剤の効果について

抄録

In the heat sterilization of bacterial spores in the presence of some disinfectants, we found in the previous experiments that they were killed abruptly after a lag period. In the present experiments, this lag period was proved possible to be reduced in time when spores were previously exposed to the relatively lower temperature advancing to the principal heating. It should be easily understood that spores which survived in the preheating were more readily killed by further application of the more severe treatment than were untreated spores.
The sterilizing power of Furaskin and vitamin K₃ was shown to be most powerful, although penta chlor phenol was relatively less effective.
