Temperature can strongly influence the biocontrol efficacy of Lysobacter strains when used against phytopathogens. We investigated the influence of temperature on physiological characteristics of Lysobacter capsici AZ78 in a biocontrol situation. L. capsici AZ78 effectively colonized tomato leaves at 15 and 25 A degrees C while exposure to 35 and 37 A degrees C was highly detrimental. Accordingly, Phytophthora infestans attacks on tomato leaves were controlled when L. capsici AZ78 was pre-exposed to 15 and 25 A degrees C for 24 h. Conversely, exposure to 35 A degrees C drastically reduced the biocontrol efficacy of L. capsici AZ78 probably by impairing anti-oomycete and proteolytic activity. Furthermore, the exposure to 15 A degrees C made the L. capsici AZ78 cells more resistant to UV light and copper ions compared to 25 and 35 A degrees C. These findings give an indication on the best temperature range for the future use of biofungicides based on L. capsici AZ78 cells.
