Solid-phase treatment with the fungus Trametes versicolor substantially reduces pharmaceutical concentrations and toxicity from sewage sludge

Ecotoxicological impact of two soil remediation treatments in Lactuca sativa seeds

“…However, most of the research has been focused on the treatment of contaminated water and wastewaters (Klavarioti et al, 2009) and in a less extent the developed approaches have been applied to soil, sediment or sludge, which can act as pharmaceuticals' reservoirs. Bioremediation with fungi (Rodríguez-Rodríguez et al, 2011), electrokinetic remediation (Guedes et al, 2014), advanced oxidation processes (Oncu and Balcioglu, 2013;Malmborg and Magn er, 2015) or nanoremediation (Machado et al, 2013;Han et al, 2015) are some of the remediation methods used for the removal of pharmaceuticals from soil, sediment and sludge.…”

Trace organic contaminants in biosolids: Impact of conventional wastewater and sludge processing technologies and emerging alternatives

“…The research group of Rodriguez-Rodriguez found that the augmentation of Trametes versicolor to sterilised dewatered sludge caused 40% to complete removal of a wide spectrum of TrOCs and significant reduction in sludge toxicity [10,[154][155][156][157]. However, treatment of non-sterilised sludge resulted in less efficient TrOC removal (e.g.…”

“…Notably, advanced oxidation processes generally achieve high treatment efficiency but have high maintenance cost and energy consumption, and their practical implementation will depend on the cost-effectiveness of the formats introduced to the market. Bioaugmentation using exogenous organisms, being a biological process, is potentially more environmentally friendly and cost effective than advanced oxidation processes [10]. Among the organisms that have been studied (e.g.…”

“…bacteria, yeasts, and fungi), WRF emerges as a promising option because it removes a wide range of TrOCs that bacteria are typically unable to degrade [157,160]. Indeed small-scale studies demonstrate that WRF can significantly remove TrOCs from digested or dewatered sludge [10,56,154,155,157]. However, a major limitation impeding its application is that WRF enzymatic activity is prone to disruption due to bacterial contamination [157].…”

“…The occurrence of TrOCs in biosolids are influenced by wastewater and sludge treatment operation parameters [4,7] and could be minimised by the addition of advanced treatment processes including ozonation [8], ultraviolet (UV) oxidation [9], and bioaugmentation [10] in the sludge treatment line. The fate of TrOCs during wastewater treatment is largely determined by their physicochemical properties (e.g.…”
