Abstract
Mold spores and hyphae infection is a serious problem and can lead to damage or loss of natural history specimens. Animal specimens play an important role in cultural exchange, science popularization, scientific research and economic window, but the preparation and preservation technology system of biological specimens is relatively unsafe and inefficient. Infection by Mold spores and hyphae is not only an acute problem that may cause damage or loss of specimens，but alsois very harmful to human beings health and polluted to environment, It is one of the principal element that restricts the development of the natural history museums. In this paper, identified the mold species of animal specimens by PCR with ITS primers, bio-microscopic observation, sequencing and phylogenetic tree analysis. The results showed the mold of animal specimens mainly belong to Aspergillus and Neurospora. than screened environmental friendly fungicides, the results show that both chitosan and nano silver can effectively inhibit the Aspergillus and Neurospora of animal specimens , the study provides a theoretical basis for the study of the new specimen fungicides and the environmental safety of the natural history museum Key words: Animal specimens, mold identification, phylogenetic tree analysis, Mold fungicides, chitosan; nano-silver
