“…The addition of nitrogen-rich nutrients (biostimulation) and potentially viable microbes (bioaugmentation) through organic materials application to soils are two effective approaches for the bioremediation of PAH-contaminated soils (Wang et al, 2016). The results in the present study showed that contact time influenced the development of catabolic activity as defined by decreases in the length of the lag phases and increases in the rates and extents of mineralization of 14 C-phenanthrene in amended soils.…”

This study investigated the impact of spent brewery grains and spent mushroom compost on the development of phenanthrene biodegradation in soil. Two aspects were considered: (i) the influence of increasing waste-to-soil ratios (1:10, 1:5, 1:2, 1:1 & 2:1) and (ii) the impact of soil-PAH contact time (1 -100 d). Biodegradation was quantified by measuring changes in the lag phase, the fastest rates and extents of mineralization of 14 C-phenanthrene, as well as changes in the number of total heterotrophic and phenanthrene degrading bacteria and fungi. The amendment of smaller amounts of the wastes (1:10 & 1:5) resulted in greatest levels of biodegradation. Microbial numbers increased in all of the amended soils but phenanthrene-degrading numbers in most amended soils did not correlate with the rates and extents of 14 C-phenanthrene mineralization. This investigation highlighted the value of waste organic materials as nutrient sources to stimulate microbial degradation of contaminants in soil.

“…White rot fungi, frequently referred to as lignin‐degrading fungus, release ligninolytic enzymes with quite a minimal substrate specificity, for example L. edodes and Pleurotus pulmonarius release Mn‐peroxidase, laccase, versatile peroxidase and lignin peroxidase, which are enzymes capable of degrading a wide range of structurally related organic contaminants, including dioxins, chlorophenols, dyes, phenols, pesticides, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls and solvents 50 . The SMS still had a high concentration of these enzymes, along with persistent mycelia capable of secreting these extracellular enzymes.…”

Commercial cultivation of edible mushrooms utilizes a large amount of lignocellulosic material as a substrate. After harvest, the leftover substrate, referred to as a spent mushroom substrate (SMS), largely remains biochemically unaltered. In light of the global rise in the number of edible mushroom production facilities, it is pertinent to sustainably manage the by‐products of the mushroom production process, particularly SMS. Following the principles of the circular economy, SMS has shown potential for a variety of applications: SMS can be used as substrate for a new cycle of mushroom cultivation or as animal feed, fertilizer, soil amendment, bioremediation agent or a substrate for renewable energy production such as biogas, bioethanol, biohydrogen, solid biofuel, bio‐crude and bio‐oil. This article summarizes the current state of knowledge in various applications, highlights recent developments in the field, discusses potential barriers and offers suggestions for the long‐term growth of the mushroom industry worldwide.

“…This so-called phytostabilization results in the conversion of soluble heavy metals into insoluble compounds, for example by binding to organic matter (Wei et al 2020 ; Yu et al 2021 ). In addition, SMS of different mushroom forming fungi can degrade OMPs (Law et al 2003 ; Purnomo et al 2010 ; Sadiq et al 2018 ; Zang et al 2020 ) or stimulate OMP degrading bacteria in the soil (García-Delgado et al 2015 ; Wang et al 2016 ). In the case of waste water, SMS of A. bisporus was shown to reduce contamination by sorbing dyes and heavy metals (García-Delgado et al 2017 ; Toptas et al 2014 ).…”

Water bodies are increasingly contaminated with a diversity of organic micropollutants (OMPs). This impacts the quality of ecosystems due to their recalcitrant nature. In this study, we assessed the removal of OMPs by spent mushroom substrate (SMS) of the white button mushroom (Agaricus bisporus) and by its aqueous tea extract. Removal of acesulfame K, antipyrine, bentazon, caffeine, carbamazepine, chloridazon, clofibric acid, and N, N-diethyl-meta-toluamide (DEET) by SMS and its tea was between 10 and 90% and 0–26%, respectively, in a 7-day period. Sorption to SMS particles was between 0 and 29%, which can thus not explain the removal difference between SMS and its tea, the latter lacking these particles. Carbamazepine was removed most efficiently by both SMS and its tea. Removal of OMPs (except caffeine) by SMS tea was not affected by heat treatment. By contrast, heat-treatment of SMS reduced OMP removal to < 10% except for carbamazepine with a removal of 90%. These results indicate that OMP removal by SMS and its tea is mediated by both enzymatic and non-enzymatic activities. The presence of copper, manganese, and iron (0.03, 0.88, and 0.33 µg L-1, respectively) as well as H2O2 (1.5 µM) in SMS tea indicated that the Fenton reaction represents (part of) the non-enzymatic activity. Indeed, the in vitro reconstituted Fenton reaction removed OMPs > 50% better than the teas. From these data it is concluded that spent mushroom substrate of the white button mushroom, which is widely available as a waste-stream, can be used to purify water from OMPs.
