The Nanhai No. 1 shipwreck is an ancient wooden ship that crashed and sank while transporting goods on the maritime Silk Road in the Southern Song Dynasty (1127-1279 AD). It has important historical significance and research value. At present, there is a serious problem of microbial diseases on the wood surface of the Nanhai No. 1 shipwreck. In order to protect the Nanhai No. 1 shipwreck, this study sampled microbial samples on the ship hull surface in September 2020 and December 2021, and analyzed the microbial diseases through scanning electron microscopy observation, high-throughput sequencing, and macro genomic sequencing methods. The biodegradation mechanism of diseased microorganisms was explored through whole genome sequencing, detection of cellulose lignin degradation ability, and detection of enzyme activity and gene expression levels of diseased microorganisms under different conditions. The results showed that there was obvious fungal colonization on the surface of the hull wood, and Fusarium solani NK-NH1 was the dominant disease fungus on the surface. Less...
