Microbial corrosion poses a significant threat to architectural heritage worldwide. This study used metagenomics investigate microbial diversity and taxonomic groups present in the door walls of Ji family’s residential houses, as well their biological functions chemical cycles. Taxonomic annotation revealed predominant taxa associated with wall corrosion, shedding light on potential impact structural integrity. Moreover, analyzing metabolites pathways these communities allows for thorough understanding functional capabilities. Our results that areas damage (dwelling bad (DBD) dwelling (DBW)) exhibited higher compared undamaged good (DGD) (DGW)), variations occurrence archaeal bacterial species. The presence bacteria was found be connected impaired function DBW, whereas changes community patterns Sphingobium Sphingomonas, decrease Cercospora proportion an increase Fusarium proportion, were correlated DBD. Both Entner–Doudoroff (ED) route sulfide oxidation processes observed both damaged locations (DBD DBW). However, nitrogen-cycling mechanisms, including dissimilatory nitrate reduction ammonium, only DBW. Furthermore, DBD specifically detected shift from methyl mercaptan (MMPA) (MeSH). research highlights intricate interplay between physical deterioration structures, emphasizing importance ecology mitigating such issues.
