Structural analysis and characterization of the main active antimicrobial ingredient produced by strain HDXY-02. (A) HPLC analysis of extraction separated from strain HDXY-02 culture broth. (B) Identification of toxoflavin with MALDI-Q-TOF-MS. (C) TLC analysis under UV light at 365 nm. (D) Antimicrobial assay. Serial dilutions of 1 μl of 10-fold conidia (107 to 105) of A. fumigatus, A. nidulans, C. albicans, and C. neoformans were spotted onto solid medium containing various toxoflavin concentrations (0 to 200 μg/ml).
