摘要

动物收藏馆的标本代表了特定时间和地点的生物多样性历史。随着时间的推移，它们的退化导致了信息的丢失，因此，评估馆藏的保存状况以采取措施对其进行管理至关重要。在本研究中，考虑到退化和生物退化指标的存在，对动物馆藏标本的保护状况进行了诊断。此外，对真菌和细菌进行了分离，并对部分优势菌种的蛋白水解活性进行了评价。结果发现，146个标本中有42%显示出与环境中常见的微生物有关的生物劣化迹象，如青霉菌和枝孢杆菌，它们在羽毛和毛发基质中表现出蛋白质水解。这表明环境条件和储存方式与标本变质之间存在关联。

Study of biodeterioration and evaluation of proteolytic activity caused by microorganisms in specimens of a zoological collection in Colombia

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.
