志丹苑元代水闸遗址木构件侵蚀微生物的防治研究

A study on the prevention and treatment of erosive microbes on the wooden components of the Yuan Dynasty Zhidan Yuan sluice ruins

为研究志丹苑元代水闸遗址木构件免受微生物危害的方案,本工作采用碘代丙炔基氨基甲酸酯(Iodopropynyl Butyl Carbamate,简称IPBC)处理的方法解决志丹苑元代水闸遗址木构件侵蚀微生物的防治问题。将遗址中处于潮湿环境条件下的木构件经IPBC处理5年后,测得其细菌总量减少89.25%,真菌总量减少55.56%,且木构件中微生物主要类群发生了很大的变化。研究表明,IPBC对于可能导致潮湿环境条件下木构件材质软腐的微生物的生长具有明显的抑制作用。本研究为控制志丹苑元代水闸遗址木构件的微生物危害提供了有效的备选方案。

This paper discusses the use of iodopropynyl butyl carbamate （IPBC） to treat erosive microbes on wooden components of the Yuan Dynasty Zhidan Yuan sluice ruins. Five years after being treated with IPBC, the wooden components in the highly moist environment of the ruins show total that the bacterial loading had decreased by 89%, the fungal loading been reduced by 56% and that the dominant group of microorganisms in the wooden components also changed significantly. The study shows that IPBC significantly inhibits the growth of microbes that cause soft rot of the wooden components in this moist environment. This study provides a preliminary plan for the protection of wood components of the Yuan Dynasty Zhidan Yuan sluice ruins.
