Abstract:
To explore the antimicrobial activity of the culture broth and supernatant of Xenorhabdus nematophila HB310 against five apple pathogens.The antimicrobial activity of the culture broth and supernatant of Xenorhabdus nematophila HB310 against Botryosphaeria berengeriana, Valsa mali, Alternaria mali, Botrytis cinerea and Alternaria mali by using two methods-growth rate method and spore germination method were investigated.The results showed that the inhibition of culture broth and supernatant of Xenorhabdus nematophila HB310 to mycelium growth of Botryosphaeria berengeriana were 76.90% and 80.79%.Overstriking mycelia and malformed cell membrane were were observed in V.mali after treatmented by the X.nematophila HB310.In addition，the X.nematophila HB310 also inhibited the spore germination.When the X.nematophila HB310 were on 50 mL/L and 25 mL/L，the spore germinations of three apples fungi were above 98%.The antimicrobial activity of the culture broth and supernatant of Xenorhabdus nematophila HB310 against five apple pathogens both had better effect.
