ROLE OF WATER IN ULTRAVIOLET-RESISTANCE OF GERMINATING BACTERIAL SPORES

[摘要] Germinating spores of Bacillus subtilis were freeze-dried and irradiated with ultraviolet ray (UV) while dry or after rehydration. It was found that the extremely high UV-resistance of the spores in the transient stage, through which germination proceeds, is lost by freeze-drying and is rapidly restored by rehydration.
