Abstract
Zoological collections shelter specimens that represent the history of biodiversity at a particular time and place. Their deterioration over time results in the loss of information, therefore, it is crucial to evaluate the state of preservation of the collections to take measures regarding their management. In this study, the state of conservation of the specimens deposited in the zoology collection was diagnosed, taking into account the presence of indicators of deterioration and biodeterioration. In addition, fungi and bacteria were isolated and the proteolytic activity of some dominant strains of fungi was evaluated. It was found that 42% of the 146 specimens analyzed showed signs of biodeterioration associated with microorganisms commonly reported in the environment, such as Penicillium sp. and Cladosporium sp., which presented proteolysis in feather and hair substrates. This suggests an association between environmental conditions and the manner of storage with the deterioration of the specimens.
期刊介绍:
Conservar Património is a journal, published three times a year, that intends to create a space for the diffusion of conservator-restorers’ studies and activities. However, at a time when Conservation-Restoration pretends to develop further through collaboration with other areas of knowledge, such as History of Art, Archaeology, Museum Studies, Chemistry, Physics, Biology and other related disciplines from the fields of the natural and social sciences, the journal also receives contributions from any other provenance as long as directed towards the multiple dimensions of the works that integrate our Cultural Heritage. Theoretical issues on the conservation activity may also be submitted.
