Abstract: © 2016, Pleiades Publishing, Inc. The capacity of fungus Aspergillus niger to degrade anionic surfactants (AS) and coproduce the detergent compatible enzymes in a liquid Czapek-Dox medium supplemented with 0.3% powder detergent Merix (Henkel, Serbia) was examined in this study. The fungus was isolated from wastewater of Lepenica River (Kragujevac, Serbia), at a place where municipal wastewater discharged into the river. The concentration of AS in tested detergent and detergent-supplemented culture media was determined using a methylene blue active substances assay. The physico-chemical and biochemical changes of pH, redox potential, biomass dry weight, activities of alkaline protease and α-amylase were evaluated during fungal growth from 3-rd to 16- th day. The detergent caused an inhibitory effect on fungal growth and biomass dry weight (about 51.4%). Nevertheless, A. niger decomposed approximately 180.2 μg/mL or 30% of AS after 16 days. The results also showed that activities of alkaline protease and α-amylase were enhanced in presence of tested detergent for 372.0 and 12.7%, respectively. Overall, the obtained results indicate the potential application of fungus in wastewater treatment and detergent industry.
