Pesquisa do Estado de Minas Gerais (FAPEMIG) As cavernas s?o ambientes pobres em carbono org?nico e alguns nutrientes que possuem caracter?sticas ?nicas onde ocorrem organismos desconhecidos ou adaptados. Os fungos que ocorrem nas cavernas podem ser end?micos ou adaptados a esse ambiente e podem apresentar metabolismo espec?fico com produ??o de compostos desconhecidos e de interesse ? humanidade. Assim, esses ambientes s?o frequentemente explorados na busca de novos compostos bioativos produzidos por fungos. O presente trabalho teve como objetivo revisar a import?ncia da identifica??o dos fungos que ocorrem em cavernas e seus potenciais biotecnol?gicos, preserva??o desses ambientes, e o isolamento de fungos que ocorrem na Caverna Velha Nova, Monjolos, localizada na Serra do Espinha?o Meridional de Minas Gerais. Na revis?o s?o abordados principalmente a import?ncia dos fungos, o impacto do turismo sobre a ecologia cavern?cola, medidas de preserva??o e a import?ncia dos estudos nestes ambientes. Para o isolamento de fungos da caverna Velha Nova, foram utilizadas amostras do ar, solo, rochas, espeleotemas e serrapilheira. Ap?s o isolamento, os microfungos foram identificados por m?todos morfol?gicos e sequenciamento do DNA gen?mico. Cento e setenta e oito isolados foram obtidos e entre estes foram identificados os g?neros Aspergillus, Amphichorda, Chaetomium, Penicillium, Humicola, Mucor, Gliomastix, Clonostachys, Myrothecium, Cladosporium, Scedosporium, Meyerozyma e Rhizopus. Devido a poss?vel identifica??o de uma nova esp?cie de Amphichorda, seu posicionamento filogen?tico foi descrito. Disserta??o (Mestrado) ?

Caves are environments poor in organic carbon and some nutrients that have unique characteristics where unknown or adapted organisms occur. Fungi that occur in caves can be endemic or adapted to this environment and can present specific metabolism with the production of unknown compounds of interest to humanity. Thus, these environments are frequently explored in the search for new bioactive compounds produced by fungi. The present work aimed to review the importance of the identification of fungi that occur in caves and their biotechnological potentials, preservation of these environments, and the isolation of fungi that occur in the Velha Nova cave, Monjolos, located in the Serra do Espinha?o Meridional of Minas Gerais. The review deals mainly with the importance of fungi, the impact of tourism on cave ecology, preservation measures and the importance of studies in these environments. Samples from the air, soil, rocks, speleothems and litter were used to isolate fungi from Velha Nova cave. After isolation, some fungi were identified with morphological methods and DNA sequencing. One hundred and seventy-eight isolated fungi were obtained and among these, Aspergillus, Amphichorda, Chaetomium, Penicillium, Humicola, Mucor, Gliomastix, Clonostachys, Myrothecium, Cladosporium, Scedosporium, Meyerozyma and Rhizopus were identified. Due to the isolation of a new species of Amphichorda, its phylogenetic position has been described.
