Abstract
The textile industry generates a high volume of wastewater with various organic and inorganic compounds, which leads to many problems at water ecosystems. Various types of dyes were used for dyeing wool, but metal-complex dyes are the most favoured because of their high affinity towards protein fibres. The main purpose of this study was to reduce the concentration of metals from wool industry wastewater by microscopic filamentous fungi of genus Aspergillus. The most significant growth of biofilm, and thus the highest ability to reduce metal content in an aqueous solution was observed by microscopic filamentous fungi Aspergillus ochraceus. After 30 days of biodegradation process, the concentration of copper was reduced by 47.94%, and of chromium by 32.55%. Aspergillus flavus reduced the concentration of chromium by 18.34%, and Aspergillus candidus by 20.71%.
