“…TrOC transformation via white-rot fungi often leads to detoxification (Jelic et al, 2012). On the other hand, increase in toxicity of white-rot fungi-treated media containinig TrOC has also been reported in the literature.…”

Nghiem, L. D. (2013). Removal of trace organic contaminants by an MBR comprising a mixed culture of bacteria and white-rot fungi. Bioresource Technology, 148 (November), 234-241. 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.

“…Despite the significant number of reports demonstrating the capacity of white-rot fungi to successfully degrade persistent TrOCs in small-scale sterile batch tests, far fewer studies have been conducted in continuous reactors (Blánquez and Guieysse, 2008, Jelic et al, 2012, RodarteMorales et al, 2012. Furthermore, only one study to date has investigated TrOC removal under non-sterile conditions as would likely be experienced in practice (Zhang and Geißen, 2012).…”

“…Due to the increasing occurrence of EPs in wastewaters, the formation of TPs during biological treatment and the mechanisms involved have been investigated for various classes of compounds {i.e., antibiotics [35,45,54], analgesics (painkillers) [39], anticonvulsants [37], anti-inflammatories [40,41], iodinated X-ray contrast media (ICM) [46,47] and anti-viral/-bacterial/-fungal agents [33,56,57]}. Most of the studies were performed in batch systems with activated sludge.…”

“…Moreover, the ability of microorganisms to degrade EPs has been studied in Erlenmeyer flasks with various microorganisms under study, such as fungus Trametes versicolor and bacterial Pseudomonas strains [37,40]. Parameters, such as pH, dissolved oxygen (O2), temperature (T) and total suspended solids (TSS), have to be monitored and adjusted to allow direct comparison with environmental conditions.…”

A B S T R A C TIdentification of transformation products (TPs) of emerging pollutants is challenging, due to the vast number of compounds, mostly unknown, the complexity of the matrices and their often low concentrations, requiring highly selective, highly sensitive techniques. We compile background information on biotic and abiotic formation of TPs and analytical developments over the past five years. We present a database of biotic or abiotic TPs compiled from those identified in recent years. We discuss mass spectrometric (MS) techniques and workflows for target, suspect and non-target screening of TPs with emphasis on liquid chromatography coupled to MS (LC-MS). Both low-and high-resolution (HR) mass analyzers have been applied, but HR-MS is the technique of choice, due to its high confirmatory capabilities, derived from the high resolving power and the mass accuracy in MS and MS/MS modes, and the sophisticated software developed.
