Effects of temperatures ranging from -40 to 49 C on the behavior of airborne Serratia marcescens, Escherichia coli, and Bacillus subtilis var. niger were investigated. Aerosol decay rates of B. subtilis spores were not significantly affected by the temperature and remained approximately constant within the temperature range studied. The survival of airborne S. marcescens and E. coli was closely related to the temperature. An increase in temperature from -18 to 49 C resulted in a progressive increase of the biological death rate, and the relationship between the biological death rate and the temperature appeared to be linear. An increase in temperature from 24 to 49 C resulted in significantly reduced aerosol recoveries of the two vegetative organisms. At -40 C, the aerosol recovery of all three agents was consistently lower than at -18 to 24 C.
研究了-40至49摄氏度的温度范围对空气中的粘质沙雷氏菌、大肠杆菌和枯草芽孢杆菌黑色变种行为的影响。枯草芽孢杆菌孢子的气溶胶衰减率不受温度的显著影响，在所研究的温度范围内大致保持恒定。空气中粘质沙雷氏菌和大肠杆菌的存活与温度密切相关。温度从-18摄氏度升高到49摄氏度导致生物死亡率逐渐增加，生物死亡率与温度之间的关系似乎呈线性。温度从24摄氏度升高到49摄氏度导致这两种营养型生物的气溶胶回收率显著降低。在-40摄氏度时，所有三种病原体的气溶胶回收率始终低于-18至24摄氏度时的回收率。
