    This study aims to explore the optimum conditions for P. eryngii var. ferulae in adsorption of sulfamethazine (SM) from synthetic solutions via reduction of chemical oxygen demand (COD). The optimum conditions were optimized using the response surface methodology (RSM) developed by the application of the quadratic model associated with the central composite design. For this aim, RSM was employed to determine the effects of some parameters on this adsorption process by fungal biomass as an effective and available adsorbent. The investigated parameters were initial concentration of sulfamethazine (70–235 mg L−1), solution pH (3–7), adsorbent dosage (0.3–1.5 g), and contact time (5–25 min). The significant factors on each experimental design response were identified from the analysis of variance. The results of RSM analyzes revealed that optimum conditions of initial SM concentration, pH, adsorbent dosage, and contact time for maximum COD removal (82%) were achieved as 400 mg L−1, 11, 1.46 g, and 15.4 min, respectively. The results showed that dead biomass of P. eryngii var. ferulae were an appropriate adsorbent for the removal of COD in the SM medium from synthetic solutions.

    This present study aims to evaluating the efficiency of P. chrysosporium (P.c) to degrade the different concentrations of malathion (MLT) (50, 100 and 150 ppm) under agitated (130 rpm) submerged culture conditions via reduction of chemical oxygen demand (COD). We have previously screening the growth of fungus in sabouraud dextrose agar (SDA) medium for 6 days. We have also determined the laccase activity during degradation process for 15 days. According to our results the fungus has achieved 99.6, 98.8 and 98.7 % COD reduction at concentration of 50, 100 and 150 ppm respectively the end of the 15 days. The highest laccase activity (180 ± 5.69 U/L) was measured at concentration of 50 ppm the end of the 15 days and the lowest activity (36 ± 3.26) was determined at concentration of 150 ppm the end of the 15 days. The dried biomass of fungus was weighted at end of the 15 days and we have determined that malathion in culture medium reduced the biomass production compared the control group (SDB + P.c). Our results showed that, P. chrysosporium could be an effective bioremediation tool for treatment of malathion containing wastewater.
