Several phototrophic microorganisms, principally cyanobacteria species predominantly sheathed forms occur as biofilms on the exposed surface of stone temples, monument as well as building facades receiving areas. A study was conducted to analyse the potential of six sub-aerial cyanobacteria species belonging to three genera, . Scytonema, Tolypothrix and Westiellopsis which were recorded as the main components in the biofilms isolated from 10 different sub-aerial sites (six building facades, three stone temples and one mortar monument) of Bhubaneswar and Puri, Odisha under laboratory culture conditions. | Morphological and biochemical characterization of sub-aerial cyanobacteria isolated from building facades and monuments of Odisha
