摘要
The objective of this study was to evaluate chemical oxygen demand (COD), protein, and carbohydrate removal from bulgur processing industry wastewater with fungal treatment. In the first stage, white rot and filamentous fungi species were tested with free cell culture at the original pH (4.5) of wastewater. Among the tested species A. parasiticus supplied the highest COD, protein, and carbohydrate removal efficiencies at the end of the incubation period (9 d). In the second stage, the removal efficiencies were compared to free A. parasiticus and immobilized A. parasiticus on waste plastic bath fiber. Moreover, the effect of initial pH of wastewater was tested on the removal efficiency of COD, protein, and carbohydrate. The results showed that immobilized A. parasiticus supplied higher removal efficiencies than the free one. Maximum removal efficiency of COD, carbohydrate, and protein was determined as 82.5 ± 1.8%, 67.9 ± 1.9% and 61.2 ± 2.3 at pH 5.5 for 12 d, respectively. © 2020 Elsevier Ltd
