Resumo

Fungi have great ecological and economic importance and can grow in low cost substrates, with the production of enzymes, promoting vast biotechnological interest. Thus, the industrial usage of fungi enzymes has rapidly expanded during the last years, especially considering those responsible for biomass degradation, such as xylanases and cellulases, which can be employed in diverse applications since the use of agricultural residues, in natura or post physical and chemical treatments, has acquired importance for environment conservation as well as energy generation. This work has the aim to identify fungi collected from some regions of Sergipe State, Brazil, and then evaluate the employment of their enzymes in the agro industrial residue treatment. In this context, bioprospection of fungi from Sergipe ecosystems allows the deep knowledge of the microorganism resident in these locations. For this, samples were collected and obtained from the Atlantic Forest, located in the Serra de Itabaiana National Park in Sergipe, Brazil. The samples were collected from soil, leaves, tree barks among others. The isolation was performed in oat solid medium (oat flour 4%, agar 2%) and the cultures were kept in incubation at 30o and 40oC. To obtain pure cultures, successive subcultures were performed and different pure cultures were obtained after isolation. The sample identification revealed the previously confirmed presence of an Aspergillus niger sample, which genus comprises well known species used as biological models, with great potential for enzyme production. The samples revealed huge fungi diversity, when considering macro and micro morphological features, expanding the knowledge about Brazilian biodiversity and improving the prediction of responses for global changes as a way to search for sustainable productive processes.CNPq, CAPES, FAPESP, FAPITEC/SE, and SISBIOTA-Brazil
