Abstract

Several studies have demonstrated the potential use of filamentous fungi in the degradation of environmental pollutants, however, are still scarce. This study aimed to evaluate the biotechnological potential of 174 filamentous fungi isolated from six species of marine sponges, which were subjected to screening on solid medium containing RBBR dye and guaiacol; the tests in liquid medium in the presence of sulfur black, indigo blue and reactive black 5 dyes, the evaluation of the production of enzymes laccase, manganese peroxidase (MnP) and lignin peroxidase (LiP), using syringaldazin, veratryl alcohol and phenol red as enzyme substrates, respectively; tested for degradation of pyrene and benzo [a] pyrene; the experimental designs; and analysis of metabolites formed in the degradation. The fungus selected Chaunopycnis alba CBMAI 1346 showed 94.54% of pyrene degradation in 35 salinity, highlighting the biotechnological potential of this fungus in the process of degradation of environmental pollutants in saline conditions.
