Identification of filamentous fungi associated with the soil of the Prosperina Protected forest

Abstract:

The Prosperina Forest is a protected area located in the city of Guayaquil-Ecuador where there is a great diversity of plants, animals and, lately, microorganisms that contribute to its conservation and maintenance. Soil samples collected at the Cuevas, Cañas and FCV stations during the dry season were analyzed by conventional microbiology methods. As a result, 38 species were identified in each station 16, 16 and 16 were obtained, respectively. The most frequent genera found in the three stations are Aspergillus, Penicillium, Trichoderma and Absidia, with less frequency Fusarium, Cladosporium, Talaromyces, Curvularia, Humicola, Gongronella, Clonostachys and Mariannea. Thirty-eight strains of filamentous fungi were cryopreserved in the CIBE Culture Collection of microorganisms (CCM-CIBE), of which 36 were unique species. The results obtained suggest that the species found. Their displacement can be affected by natural and human factors. In addition, we confirm biocontrol microorganism as Purpureocillium, a nematophagous and Cladosporium that, may have a high potential in bioremediation activities of importance for agriculture and soil recovery, which corroborates that the Protected Forest is a rich source of microorganisms with a great reputation for its conservation.
