Role of Micro-Organisms in Biodeterioration of Sandstone in Heritage Buildings

Abstract

The growing concern for the preservation and protection of heritage building has led to a greater interest in the findings of biodeterioration occurring on these buildings. The cultural heritage objects are damaged by various agents like atmospheric agents, condensation or capillary humidity, temperature range, human action and micro-organisms. A wide variety of organisms like bacteria, fungi, algae and plants etc. have been reported in the degradation of heritage structures. Micro-organisms ability in production of pigments and organic acid plays a crucial role in discoloration and degradation of different types of stone in cultural heritage building objects. The study focuses on the types of micro-organisms that are responsible for the biodeterioration of heritage buildings as well as the preventive measure and treatment done to restore the original form of the sandstone structures. The research is also supported and reinforced with a case study of Sher Shah Suri’s tomb at Sasaram, Bihar.
