Thermal Death Range of Pseudomonas solanacearum under Various Conditions

Abstract

The thermal death range of Pseudomonas solanacearum was examined under several conditions. The bacterium strains belonging to biovars II and III were more tolerant than those belonging to biovars I and IV at 40, 43, and 45°C in sterilized water. All strains of the bacterium was killed at 43°C for a day regardless belonging biovars. The bacterium was able to survive in the diseased plant residues and in soil at 43°C for 2 days and at 40°C for 5 days.
