Removeal of Chromium Present in Water and Industrial Wastewater Using Resistant Fungi

Chromium is present in different types of industrial effluents, causing environmental pollution. In this paper, it is aimed to quantify the chromium sorption ability of native fungi (Mucor sp, Aspergillus sp., Alternaria sp and Fusarium sp) isolated from industrial waste water at the optimum absorption conditions. Higher absorption percentage is noted at lower initial concentration of Cr ions while the absorption capacity of the biomass increases with higher concentration. Uptake was determined by spectrometry at the wavelenght of 540nm. This investigation showed that biosorprion of Cr(VI) ions using native fungi induces the industrial effluent to be corresponding with environmental laws and standards. Results from this study showed that bioabsorption capacities of Mucor, Aspergillus sp(B), Aspergillus sp(G) and Alternaria were 60. 2, 38.2, 35.1 and 34.7 mgCr6+/g dry biomass, respectively. Fungal biomass showed significat sorption Cr: Mucor (99.9% for 150 mg /l Cr6+, %50+ 1 for 250 mg/l Cr6+), Aspergillus sp(B) (%99 for 150 mg/l Cr6+), Aspergillus sp (G) 99.8 for 100 mg/l Cr 6+, Alternaria %50 + 2 for 100 mg/l Cr6+).
