Removal of trace organic contaminants by an MBR comprising a mixed culture of bacteria and white-rot fungi AbstractThe degradation of 30 trace organic contaminants (TrOC) by a white-rot fungus-augmented membrane bioreactor (MBR) was investigated. The results show that white-rot fungal enzyme (laccase), coupled with a redox mediator (1-hydroxy benzotriazole, HBT), could degrade TrOC that are resistant to bacterial degradation (e.g. diclofenac, triclosan, naproxen and atrazine) but achieved low removal of compounds (e.g. ibuprofen, gemfibrozil and amitriptyline) that are well removed by conventional activated sludge treatment. Overall, the fungus-augmented MBR showed better TrOC removal compared to a system containing conventional activated sludge. The major role of biodegradation in removal by the MBR was noted. Continuous mediator dosing to MBR may potentially enhance its performance, although not as effectively as for mediator-enhanced batch laccase systems. A ToxScreen3 assay revealed no significant increase in the toxicity of the effluent during MBR treatment of the synthetic wastewater comprising TrOC, confirming that no toxic by-products were produced. 2013 Elsevier Ltd.

“…Laccase activity was then calculated from the molar extinction coefficient ε = 49.6/mM/cm and expressed in µM substrate (DMP)/min. Mycelium bound laccase activity of the MBR biomass was determined as per the method described by Yang et al (2013a) and presented as µM (DMP) /min/ g MLSS.…”

“…A two stage reactor was successful in degradation azo dye Reactive Blue 222 through combination of Photo-Fenton's and aerobic treatment with two white-rot fungi P. ostreatus IBL-02 and P. chrysosporium IBL-03 [128]. A white-rot fungus, T. versicolor showed significant removal of two TrOCs (80-90 % bisphenol-A removal and 55 % diclofenac removal) in a continuous flow fungal membrane bioreactor in non-sterile environment at 2 days hydraulic retention time (HRT) [129]. A novel strategy was employed for degradation of HMW-PAHs by Bhattacharya et al [125] consisting of biphasic approach using white-rot fungus P. chrysosporium.…”

Bioremediation refers to cost-effective and environment-friendly method for converting the toxic, recalcitrant pollutants into environmentally benign products through the action of various biological treatments. Fungi play a major role in bioremediation owing to their robust morphology and diverse metabolic capacity. The review focuses on different fungal groups from a variety of habitats with their role in bioremediation of different toxic and recalcitrant compounds; persistent organic pollutants, textile dyes, effluents from textile, bleached kraft pulp, leather tanning industries, petroleum, polyaromatic hydrocarbons, pharmaceuticals and personal care products, and pesticides. Bioremediation of toxic organics by fungi is the most sustainable and green route for cleanup of contaminated sites and we discuss the multiple modes employed by fungi for detoxification of different toxic and recalcitrant compounds including prominent fungal enzymes viz., catalases, laccases, peroxidases and cyrochrome P450 monooxygeneses. We have also discussed the recent advances in enzyme engineering and genomics and research being carried out to trace the less understood bioremediation pathways.

“…Despite implementing waste management programs, occasionally small volumes of NDWW could be mixed with DWW and be released to the sewage system. This represents a risk for receiving water bodies due to the chemical complexity of NDWW that may contain potentially dangerous substances such as dyes, endocrine-disruptors, pharmaceutical compounds, organic pollutants and pathogenic microorganisms resistant to antimicrobial [1] [2] [3] [4].

In this study, a pilot wastewater treatment plant was used to evaluate the co-treatment of biological-staining residues and domestic wastewater under non-sterile conditions. A novel microbial consortia formed by Trametes versicolor, Trametes sp, Pleurotus ostreatus, Pseudomonas fluorescens, Pseudomonas azotoformans, Pseudomonas sp, Enterobacter xianfangensis and Bacillus subtillis was inoculated in an extended aeration type bio-reactor. The treatment units were operated during three consecutive cycles during a period of 147 h. After the last operating cycle, the concentrations of Chemical Oxygen Demand, Biochemical Oxygen Demand, Color Units, Total suspended solids, and the pH value were 1695 mg/L, 105 mg/L, 106 CU, <0.001 mg/L and 5.8 respectively. The initial values of wastewater were 6755 mg/L (COD), 2005 mg/L (BOD 5 ), 1367 (CU), 566 mg/L (TSS) and 7.0 (pH) respectively. The reduction of pollutants load was related with the ratio of the two types of wastewater (3.5:0.5) combined to increase biodegradability, the concentration sults of root weight showed that there are significant differences between the initial water and the effluent obtained after the operational cycles (p = 0.00470). The highest root weights (1 -1.12 g) were found in plants irrigated with water obtained from the last treatment cycle.
