Inhibitory Effect of Cinnamaldehyde on Main Destructive Microorganisms of Nanhai No. 1 Shipwreck

Nanhai No. 1, a shipwreck in the Southern Song Dynasty, China, has history of more than 800 years. It was salvaged 2007 and is now on display Guangdong Maritime Silk Road Museum. Due to fact that hull wooden cultural relic exposed air, biological corrosion biodegradation caused by microorganisms are key problems protection. At present, antimicrobial agent Euxyl® K100 (isothiazolinone) significant effect field, but it certain negative impact environment archeologists. In order reduce use chemical agents, we evaluated inhibitory effects cinnamaldehyde main destructive 1. Cinnamaldehyde active component cinnamon, broad-spectrum properties. The paper diffusion method, gas method minimum concentration experiment were used detect We found had Bacillus tequilensis NK-NH5, megaterium NK-NH10, velezensis NK-NH11, sp. NK-NH15, NK-NH16, NK-NH17, Fusariumsolani NK-NH1 Scedosporiumapiospermum NK.W1-3. same time, fungi bacteria. Finally, verified can effectively inhibit growth water, for storing scattered wood blocks 1 through laboratory simulation experiments. Cinnamaldehyde, as an environment-friendly agent, great significance protecting water-saturated relics from microbial degradation future.
