Abstract	BACTERIAL DIVERSITY IN BIOFILMS ON EXTERNAL SURFACES OF HISTORIC BUILDINGS IN PORTO ALEGRE1 Author: Greicy Kiel Adviser: João Ruy Jardim Freire The preoccupation in conserve of historic monuments has increased day by day in the scientific community. New research groups have arisen, dedicated to studying factors that can be taken historic monuments in ruin , and methods to solve them. The presence of bacteria in rocks or historic monuments of stone has been confirmed in many studies. Four churches and the Vice-Governor ́s office, all of historic importance, were studied in Porto Alegre, using traditional microbiological methods, with the aim of valuing bacterial diversity of historic and cultural patrimony and to assess microdiversity on historic buildings using cell morphology and culture in the laboratory. A large number of microorganisms was found in each biofilm. Most of the Gram positive bacteria were of the Bacillus genus. The isolates identifying of Bacillus spp. were resistant to 5% salt (NaCl) and some to 10%, indicating their adaptation to dry exposed surfaces. This study, together with the current literature, suggests that there are many problems with the classification of microbial diversity and that must be considered in attempts to control biodeterioration of buildings. 1 Master’s Dissertation in Agricultural and Environmental Microbiology, Faculdade de Agronomia, Universidade Federal do Rio Grande do Sul, Porto Alegre (78p.).
