Abstract

Historical sand stone monuments, is subjected to degradation induced by diverse mycoflora. Fungi are among the most active microorganisms in these processes. Fungal ability in production of pigments and organic acids have crucial role in discoloration and degradation of different types of sandstone in historical monuments. This investigation focuses on myco-ecological analyses of microbial bio-film from Mama Bhanja temple of Chhattisgarh State. The seven (07) fungal organisms with specific distribution on sandstone monuments were isolated. Fungi from Ascomycotina as well as Deuteromycotina were more frequent. The most frequent isolated fungal species from these historical sandstone monuments are Aspergillus niger, Curvularia lunata, Rhizoctonia solani and Aspergillus flavus. Aspergillus niger was common in almost all the sandstone structures of this monument. The frequency and relative frequency of these fungal organisms associated with deteriorated sandstone monuments site provides valuable data for future studies. KEY WORDS:- Degradation, Deterioration, Sandstone monument, Myco-ecological, Biofilm.
