| Cathedrals, churches, cemeteries are part of the cultural heritage of urban communities. Conservation actions that are carried out on such monuments have to be accompanied by a careful analysis of biotic and abiotic agents that impact the materials of their facades. The goal of this paper is to assess the development of biofilms on brick facades at La Plata Cathedral (Argentina). La Plata Cathedral is the main Catholic Church in Neogothic style in La Plata, Buenos Aires, Argentina, and one of the largest in Latin America. It was projected by Ing. P. Benoit and built in the period 1884-99. Since then the complex microbial communities forming biofilms on La Plata Cathedral are quite diverse including bacteria, fungi, diatoms and other algae. By SEM we observed grooves and pitting that could be caused by the attack of fungi and phototrophs on the substrate (brick). Bacteria, cyanobacteria and fungi produce acid metabolites, which enhance the aggressive effects of climate and play an important role in the biogeochemical deterioration of construction materials. | |
