摘要： The effects of esterified lactoferrin (ELF) and lactoferrin (LF) on blue mold caused by Penicillium expansum in apple fruit stored at 25 degrees C were investigated. Both ELF and LF provided an effective control and strongly inhibited spore germination and germ tube elongation of P. expansurn in vitro. Assessment by propidium iodide staining combined with fluorescent microscopy revealed that the plasma membrane of P. expansum spores was damaged more seriously by ELF than by LF treatment, and the leakage of protein and sugar was higher from ELF-treated mycelia. Interestingly, ELF treatment induced a significant increase in the activities of chitinase, beta-1,3-glucanase, and percoddase in apple fruit, whereas both LF treatment and the control showed no obvious difference. These findings indicated that the effects of ELF on blue mold in apple fruit might be associated with the direct fungitoxic property against the pathogens and the elicitation of defense-related enzymes in fruit.
