“…versicolor NRRL 66313 and P. ostreatus HK 35 at initial concentrations of 25 ng•L -1 and 350 µg•L -1 respectively, in an effluent from secondary treatment (Kresinová et al, 2017;Shreve et al, 2016). Nguyen et al (2013) also reported the removal of benzophenone, octocrylene and oxybenzone (three UV filters) with values of 68, 90 and 96%, respectively.…”

“…In those streams, the fungal process would be a treatment to decrease micropollutant concentration prior to discharge to the WWTP. If a fungal treatment were to be included in a conventional WWTP, some options could be considered: first, the increase of SRT or fungal concentration in the reactor could be optimized in order to allow higher removal efficiencies, thus enabling the coupling; second, low hydraulic retention times, between 6 to 12 h, are enough to remove several families of compounds such as analgesics, anti-inflammatories (Marco-Urrea et al, 2010a and endocrine disruptors (Kresinová et al, 2017;Shreve et al, 2016), although enzyme washout should be taken into consideration. Therefore, wastewaters containing mainly these families of pollutants could be treated with fungal systems at low HRTs.…”

Can white-rot fungi be a real wastewater treatment alternative for organic micropollutants removal? A review

Micropollutants are a diverse group of compounds that are detected at trace concentrations and may have a negative effect on the environment and/or human health. Most of them are unregulated contaminants, although they have raised a concern in the scientific and global community and future regulation might be written in the near future. Several approaches have been tested to remove micropollutants from wastewater streams. In this manuscript, a focus is placed in reactor biological treatments that use white-rot fungi. A critical review of white-rot fungal-based technologies for micropollutant removal from wastewater has been conducted, several capabilities and limitations of such approaches have been identified and a range of solutions to overcome most of the limitations have been reviewed and/or proposed. Overall, this review argues that white-rot fungal reactors could be an efficient technology to remove micropollutants from specific wastewater streams.

“…Due to their lack of substrate specificity, these enzymes are also capable of degrading a variety of xenobiotics (Křesinová et al, 2018). Furthermore, the fungi of this genus differ in the degradation ability of these substances due to the qualitative and quantitative characteristics of their individual enzymes (Kamida et al, 2005).…”

“…have a high potential as an agent in the recovery of environments contaminated by a variety of recalcitrant compounds (Zhuo et al, 2017). The fungi produce a high amount of mycelial mass and are considered good biosorbents due to the chemical composition of their cell walls and the mechanisms of their resistance to the conditions of environmental stress (Křesinová et al, 2018). The chemical composition of the cell walls of the fungi is responsible for attracting and retaining metals in the fungal biomass through the electrostatic interactions, a process known as biosorption (Gupta and Rastogi, 2009).…”

Fungi have a large capacity to produce enzymes that are capable of degrading compounds. In this regard, soluble dyes are often used as a means of evaluating and selecting strains with potential for biodegradation. This study verified the capacity of the strains of Pleurotus sp. in degrading methylene blue dye, in order to identify the strains with potential for the bioremediation. For this reason, a total of seven strains of Pleurotus sp. were grown in a potato liquid medium with the methylene blue dye at the concentrations of 0.02 g L -1 and 0.04 g L -1 . The results of the absorbances showed that all the isolates were visibly able to reduce the media staining following seven days of growth. However, a reduction of approximately 80% in the staining was observed for the strains named ERY, HI, and SB compared to the control. Thus, it was observed that these strains could be used in the color removal bioprocesses and in the biodegradation of pollutant compounds.

“…It was reported that WRF could remove various organic pollutants, such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls, textile dyes, insecticides and EDCs [56,57]. For example, the white-rot fungus Pleurotus ostreatus HK35 [58], which is fairly easy to cultivate and to fructificate and has great potential for bioremediation, was tested in the degradation of seven typical representatives of EDCs (BPA, E1, 17β-estradiol, estriol, 17α-ethynylestradiol, TCS and 4-n-nonylphenol). Under model laboratory conditions, the degradation efficiency of Pleurotus ostreatus HK35 was greater than 90% in 12 days.…”

Environment-Friendly Removal Methods for Endocrine Disrupting Chemicals

et al. 2020

In the past few decades, many emerging pollutants have been detected and monitored in different water sources because of their universal consumption and improper disposal. Among these, endocrine-disrupting chemicals (EDCs), a group of organic chemicals, have received global attention due to their estrogen effect, toxicity, persistence and bioaccumulation. For the removal of EDCs, conventional wastewater treatment methods include flocculation, precipitation, adsorption, etc. However, there are some limitations on these common methods. Herein, in order to enhance the public’s understanding of environmental EDCs, the definition of EDCs and the characteristics of several typical EDCs (physical and chemical properties, sources, usage, concentrations in the environment) are reviewed and summarized in this paper. In particular, the methods of EDC removal are reviewed, including the traditional methods of EDC removal, photocatalysis, biodegradation of EDCs and the latest research results of EDC removal. It is proposed that photocatalysis and biodegradation could be used as an environmentally friendly and efficient EDC removal technology. Photocatalytic technology could be one of the water treatment methods with the most potential, with great development prospects due to its high catalytic efficiency and low energy consumption. Biodegradation is expected to replace traditional water treatment methods and is also considered to be a highly promising method for efficient removal of EDCs. Besides, we summarize several photocatalysts with high catalytic activity and some fungi, bacteria and algae with strong biodegradability.
