摘要
[Objectives]The research was to explore the antifungal effects of citronellal,wintergreen oil and their composite essence on Penicillium citrinum.[Methods]The inhibition zones of citronellal,wintergreen oil and their composite essence against P.citrinum were determined by disk diffusion method,and the growth of inhibition zone plate was observed.The fumigation fungicidal rate of fungi-bearing rice paper within 7 d was determined by plate counting method.[Results]Citronellal had strong antifungal effect,and wintergreen oil could slow down the growth rate of P.citrinum.The combination of citronellal and wintergreen oil had a synergistic effect.As fumigants,both citronellal and composite essence had fungicidal rates up to 100%within 7 d.Combined with anaerobic treatments,all the three essential oils could improve the fungicidal efficiency.The adsorbent in deoxidizing agent would adsorb the essential oils,so that their fumigation had a certain slow release effect.[Conclusions]This study can provide a more friendly and efficient method for the prevention and control of cultural relics mold.
