During the processing of raw materials from the sugar-alcohol industry, large quantities of wastewater is produced, which is inappropriate to release into water bodies without previous suitable treatment. The bioremediation is used to decompose organic waste until an innocuous condition or to a concentration below the limit under legislation; moreover fungi have very important role in this strategy due to the secretion of hydrolytic enzymes. In the present study, we evaluated the behavior of fungi isolated from residuals of the waste treatment station from a sugar-alcohol industry in face to the phenols degradation, as tannic acid and other compounds of agri-industrial wastewater supplemented with specific nutrients. Among different fungi, those identified as Aspergillus sp. and Cladosporium sp. presented the best rates of production of enzymes that degrade tannic acid, such as laccase, while Mucor sp. was better to remove the Chemical Oxygen Demand (COD) and the total phenol content, followed by Cladosporium sp., Phanerochaeta chrysosporium and Geotrichum candidum.
