ABSTRACT

The survival of airborne Flavobacterium sp. in particle sizes ranging from 1 to 5 µm was significantly influenced by atmospheric temperature. A progressive increase in temperature from –18 to 49 C resulted in increases in death rates of the airborne organism. The lowest death rates were observed in the temperature range of –40 to –18 C, and the highest death rates were observed in the 29 to 49 C range. At 24 C, the survival of airborne Flavobacterium did not appear to be significantly affected by relative humidity ranging from 25 to 99%.
