Abstract

Fungi play a considerable role for the deterioration of cultural heritage. Due to their enormous activity. Fungal ability in production of organic acid has a crucial role in discoloration and degradation of different types of stone in culture heritages. Additionally, stone objects may support novel communities of microorganisms that are active in the biodeterioration process. In addition, microorganisms also colonize these monuments over a period of time, resulting in formation of biofilms; their metabolites lead to physical weakening and discoloration of stone eventually. This process, known as biodeterioration, leads to a significant loss of cultural heritage. This investigation focuses on mycological analyses of microbial biofilm from Pundarikakshan Perumal temple at Thiruvellarai, in Trichy District. In this work, the ability of fungi producing organic acids and biodiversity of fungal consortia was examined on the stone monuments.

Conclusion

Microorganisms play an important role in the biodeterioration of objects of cultural and historical significance, but their detailed biochemical and Eco physiological functions and roles remain unclear. Although many studies have reported that a high diversity of microorganisms participate in the biodeterioration process. Fungi is highly frequent in sample I. Isolates were identified based on cultural characteristics. Research on the biodeterioration of historical materials has revealed the presence of huge microbial diversity consisting of both biofilm producing and non-producing colonization. Few are organic acid producers and predominantly non organic aid producers.
