| Popis: | Abstract Environmental pollution may be considered one of the main problems affecting the world population. As the effluents from textile industries are the largest representatives of sources of pollution of water bodies due to the disposal of colored compounds in the environment. Microorganisms capable of thriving in textile wastewater may exhibit metabolic machinery to synthesize a wide variety of enzymes and/or secondary metabolites of industrial interest. The present work investigated the biotechnological potential of filamentous fungi from wastewater of a textile industry for the production of laccase, cellulase, amylase and lipase enzymes and their potential for discoloration capacity of Remazol Brilliant Blue R synthetic dye. The isolate Aspergillus sydowii (ITF 30) presented the best cellulase (46.74 U mL-1), amylase, lipase and laccase (0.0273 U L-1) production, as well as RBBR dye discoloration ability in solid medium, followed by isolate Aspergillus sydowii (ITF 27) able to synthesize cellulase, amylase and laccase and had the capacity to discolor 74.7% of RBBR in liquid medium. The results of the present work encourage future studies of characterization, optimization and purification of the enzymes encountered, aiming to be used in bioremediation processes of textile industrial effluents. |
