The effects of the secondary metabolites of the citrus endophytic fungus Nemania sp. LJZ-Y-11 on the citrus canker disease-causing pathogen Xanthomonas citri subsp. citri.

ABSTRACT: The bacterium Xanthomonas citri subsp. citri (Xcc), which causes citrus canker disease, has caused great harm to citrus production worldwide. In this study, we aimed to clarify the antibacterial activities of extracts prepared with solvents of different polarities from the fungus Nemania sp. LJZ-Y-11 against Xcc, isolate and identify the active secondary metabolites, as well as evaluate the effects of the active compound on the Xcc. The results showed that extracts displayed significant antibacterial activities with the minimum inhibitory concentrations (MICs) and the minimal bactericidal concentrations (MBCs) at 0.3125 - 5 mg.mL^-1 and 0.625 - 5 mg.mL^-1, respectively. Especially the ethyl acetate (EtOAc) extract displayed the highest activity (MIC = 0.3125 mg.mL^-
