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°C while exposure to 35 and 37°C was highly detrimental. Accordingly, Phytophthora infestans attacks on tomato leaves were controlled when L. capsici AZ78 was pre-exposed to 15 and 25°C for 24h. Conversely, exposure to 35°C drastically reduced the biocontrol efficacy of L. capsici AZ78 probably by impairing anti-oomycete and proteolytic activity. Furthermore, the exposure to 15°C made the L. capsici AZ78 cells more resistant to UV light and copper ions compared to 25 and 35°C. These findings give an indication on the best temperature range for the future use of biofungicides based on L. capsici AZ78 cells.
