The sporicidal activity of ozone in the gas phase was investigated. Spores of six strains of Bacillus species deposited on filter paper or glass fibre filter were conditioned at different relative humidities (r.h.), and then exposed to ozone ranging in concentration from 0.5 to 3.0 mg/l at different r.h. There was a lag phase in the initial stage of exposure followed by an exponential decrease in the number of survivors with time, although no lag phase was observed with one strain. Inactivation rates increased with increasing exposure r.h. while no significant inactivation was attained at a r.h. of 50% or below. The conditioning r.h. influenced the duration of the lag phase. The D-values (decimal reduction time) in the logarithmic phase varied roughly in inverse proportion to the ozone concentration.
研究了气相中臭氧的杀孢子活性。将沉积在滤纸或玻璃纤维滤器上的六种芽孢杆菌菌株的孢子在不同相对湿度（r.h.）下进行预处理，然后在不同相对湿度下暴露于浓度范围为0.5至3.0 mg/l的臭氧中。暴露初期有一个滞后期，随后存活菌数随时间呈指数下降，不过有一个菌株未观察到滞后期。灭活率随暴露相对湿度的增加而增加，而在50%或更低的相对湿度下未达到显著灭活效果。预处理相对湿度影响滞后期的持续时间。对数期的D值（十进制减少时间）大致与臭氧浓度成反比。
