The Impact Study of the Exchanges between the Microorganism Communities on the Surfaces from Constanta Roman Mosaic and Anthropic Interactions

Abstract

The constituent elements of the Roman Mosaic from Constanta are damaged under the activities of microorganisms present both on surfaces and in the airborne microbes. The predominance of microorganisms on the different surfaces of the edifice has led to multiple damage such as discoloration, pigmentation, wall degradation and exposed ceramic objects. Through this study we aimed to invest the diversity of microorganisms on the various substrates and levels as well as microclimate conditions. From the samples collected there were isolated and identified microorganisms, many of them with pathogenicity risks for staff and visitors. Thus, for the improvement of the surrounding conditions of the Roman Mosaic exhibition room, the need for management is aimed at reducing the microbial contaminations, based on understanding the changing conditions in the microclimate and decreasing the damage biofilm. Our study can be seen in a broader procedural in the current COVID-19 pandemic conditions.
