A Influência dos Microrganismos na Degradação da Rocha de Bens Tombados do Parque Nacional da Tijuca

Research identifies the significant role of microorganisms, particularly fungi from the genera Penicillium and Trichoderma, in accelerating the degradation of marble structures within Tijuca National Park. These fungi, thriving in the park's high humidity, secrete acids that contribute to the deterioration of the historic marble bathtubs, altering their aesthetics and physical integrity. The study employed chemical analysis, X-ray diffraction, and scanning electron microscopy (SEM) to characterize the marble as calcitic and assess microbial impact on its degradation. Findings highlight the need for targeted conservation strategies to mitigate biological weathering in such culturally significant sites.
