| Abstract | Resumo O Parque Nacional da Tijuca, situado na zona central da cidade do Rio de Janeiro, protege uma das maiores florestas urbanas do mundo, embora sua vegetacao resulte de reflorestamento durante o periodo do Segundo Reinado. E o Parque Nacional mais frequentado do Brasil, recebendo visitantes de diversos lugares que sao atraidos pelas suas trilhas e paisagens. Distribuidas nele, existem seis banheiras esculpidas em marmore branco, segundo historiadores, proveniente de Carrara, na Italia, e teriam sido trazidas ao Parque durante o seculo XIX. A acao das intemperies associada a acao antropica conduz a destruicao de diversos monumentos petreos de importante significado historico e cultural. O caso das banheiras da Floresta da Tijuca nao e diferente, a atuacao desses agentes tem resultado em uma serie de patologias e danos tanto na estetica, quanto na integridade fisica das pecas. Com base nestes fatores, foram realizados estudos com a finalidade da caracterizacao da deterioracao do marmore que compoe as banheiras atraves do recolhimento de amostras e submissao destas a analise quimica, a difracao de Raios-X, ao MEV, alem de verificar o efeito da propagacao microbiologica nesse processo. Por meio desse estudo foi possivel identificar a predominância de calcio, caracterizando o marmore como calcitico, alem da presenca de fungos dos generos Penicillium e Trichoderma. Que se proliferam devido a alta umidade do local e podem secretar acidos que aceleram a degradacao das rochas. Palavras Chave: marmore, banheiras, microrganismos Abstract THE INFLUENCE OF MICRORGANISMS IN THE DEGRADATION OF THE ROCK OF CULTURAL HERITAGE ASSETS IN TIJUCA NATIONAL PARK. The Tijuca National Park is located in the central area of the Rio de Janeiro, protects stone of the largest urban forests in the world, although its vegetation results from reforestation during the period of the Second Empire. It is the most visited national park in Brazil. It receives visitors from many places, who are attracted by their trails and landscapes. Distributed through the park, there are six white marble carved bathtubs, according to historians, from Carrara, Italy, which probably were brought to the park during the nineteenth century. The weathering processes associated to anthropic action leads to the destruction of many stone monuments of historic and cultural significance. The case of the Tijuca Forest bathtubs is no different, the action of these agents resulted in a number of diseases and damages not only to the aesthetics aspects, but also to the physical integrity of some their structural parts. As an example, the color change caused mainly by the death of microorganisms. Based on these factors, studies have been conducted with the purpose of characterizing the deterioration of marble that make up the bath by collecting samples and submission of these will chemical analysis, the diffraction of X-rays, the SEM, and check the effect of the spread microbiological this process. Through these studied was possible to identify the prevalence of calcium, featuring marble as calcite, besides the presence of fungi Penicillium and Trichoderma.
