Effect of aerosolization on subsequent bacterial survival.

摘要: To determine whether aerosolization could impair bacterial survival, Pseudomonas syringae and Erwinia herbicola were aerosolized in a greenhouse, the aerosol was sampled at various distances from site of release by using all-glass impingers, survival followed impingers for 6 h. Bacterial subsequent to P. E. not impaired 1 m release. 3 15 temperature 12 degrees C relative humidity 80% survived 35- 65-fold better than released 27 40%. No difference observed following same humidity. Bacteria sprayed directly onto bean oat plants established stable populations comparable numbers on both over an 8-day period inoculation. that inoculated adjacent drifting downwind up 5 detectable initial population 10(2) CFU/g oats 10(5) beans 2 h after spray. However, undetectable within 48
