Abstract
As microorganisms inhabit these monuments over time, biofilms are formed, and the stone becomes physically weakened and discolored due to microbial metabolites. Cultural legacy is significantly lost as a result of this process, which is called biodeterioration. The most common taxa were found to be closely related to Bacillus species, Arthrobacter species, Staphylococcus spp. and Paenibacillus species after purification and 16S rDNA sequencing of bacteria living on historical monuments. Apart from bacteria, there have also been reports of some fungal strains belonging to the genera Alternaria, Fusarium, Aspergillus, and Penicillium. to create conservation plans that work in order to repair monuments and stop biodeterioration. This paper provides an overview of some well-known biodeterioration processes that have been seen on various materials, including stone and construction materials, items on display in museums and libraries, human remains, and materials used in burial.
Keywords: Microorganisms, Biodeterioration, Microbial communities, Microbial-Induced Weathering, Heritage Stone Monuments.
