Avaliação do potencial de produção de enzimas extracelulares por fungos endofíticos do babaçu

Abstract

Currently, enzymes are substances that occupy the second place in importance to society, due to the most varied sectors in which they find application, for this reason they are considered products of high biotechnological value. Under the justification of meeting a growing demand for new sources of enzymes, the present work aimed to explore babassu endophytic fungi as producers of extracellular enzymes. From the fruits at different stages of maturation (green, ripe and post-harvest) and leaves, 12 endophytic fungi were isolated, of which 11 were tested for the production capacity of cellulases of the FPAses type. Among the tested isolates, CA1M showed cellulolytic activity of 2,27 FPU/g of substrate, higher than that recorded for the other isolates. The record of cellulase-producing endophytic fungi associated with babaçu, species native to the Amazon region, contributes to the enhancement of this natural resource, as well as providing a new renewable source in the search for enzymes with potential for industrial application.
