“…Liu et al reported that the toxicity of 2, 4, 5-trichlorophenol and heavy metals inhibited the biomass and fruiting time of C. maxima [10]. And, the addition of either Cd or Phe resulted in the decrease of Pleurotus cornucopiae biomass [19]. In this experiment, the presence of fluoranthene promoted the growth of P. eryngii, which resulted in a much higher capacity to accumulate metal and remove fluoranthene.…”

This study focused on the bioremediation role of Pleurotus eryngii in different characteristics soils contaminated with nickel (Ni) and fluoranthene. The results of bioremediation experiments showed that fluoranthene had a positive effect on the growth of P. eryngii, whereas Ni exerted a negative influence. The concentration of fluoranthene significantly decreased in inoculated soil accounting for 86.39-91.95% of initial concentration in soils and 71.46-81.76% in non-inoculated soils, which showed that the dissipation of fluoranthene was enhanced by mushroom inoculating. The highest removal rates of fluoranthene in sandy loam, loamy clay, and sandy soils reached to 87.81, 86.39, and 91.95%, respectively, which demonstrated that P. eryngii was more suitable for the bioremediation of sandy soil contaminated with fluoranthene. In addition, the presence of Ni tended to decrease the dissipation of fluoranthene in inoculated soil. Higher ligninolytic enzymes activities were detected in inoculated soils, resulting in the enhanced dissipation of fluoranthene in inoculated soils. Furthermore, P. eryngii had the ability to uptake Ni (4.88-39.53 mg kg ) in co-contamination soil. In conclusion, the inoculating of P. eryngii was effective in remediating of Ni-fluoranthene co-contaminated soils.

“…7). In mushrooms, antioxidants exhibit different responses to different stresses (Jiang et al 2015; Zhang et al 2016a). These results suggested that the high level of H 2 O 2 or O 2 − in CdCl 2 , NaCl and H 2 O 2 -stressed mycelia was caused, at least in part, by an impaired detoxifying capacity of ROS.…”

Hydrogen-rich water alleviates the toxicities of different stresses to mycelial growth in Hypsizygus marmoreus

In plants, hydrogen gas (H2) enhances tolerance to several abiotic stresses, including salinity and heavy metals. However, the effect of H2 on fungal growth under different stresses remains largely unclear. In this study, hydrogen-rich water (HRW) was employed to characterize physiological roles and molecular mechanisms of H2 in the alleviation of three different stresses in basidiomycete Hypsizygus marmoreus. Our results showed that HRW treatment, of which the H2 concentration was 0.8 mM, significantly reduced the toxicities of CdCl2, NaCl and H2O2, leading to significantly improved mycelial growth and biomass. These beneficial effects could be attributed to a significantly decreased formation of malondialdehyde (MDA). Besides, HRW treatment significantly increased the activities of antioxidants (SOD, CAT and GR) as well as the gene expressions of these antioxidants (SOD, CAT, and GR) at the mRNA level. In vivo detection of reactive oxygen species (ROS), including H2O2 and O2 −, as well as lipid peroxidation provided further evidence that HRW could significantly improve tolerances of CdCl2, NaCl and H2O2. Furthermore, pyruvate kinase was activated in the mycelia treated with HRW, along with its induced gene expression, suggesting that HRW treatment enhanced the glucose metabolism. Taken together, our findings suggested that the usage of HRW could be an effective approach for contaminant detoxification in H. marmoreus, which was similar with the effects of HRW in plants, and such effects could be also beneficial in entire agricultural system.Electronic supplementary materialThe online version of this article (doi:10.1186/s13568-017-0406-1) contains supplementary material, which is available to authorized users.

“…The bioremediation mechanisms for combined pollution of PAHs and toxic metals by fungi and bacteria are also well documented (Liu et al 2017). For example, Jiang et al 2015 cornucopiae and reduce oxidative stress (Jiang et al 2015). However, there are also studies where fungal-bacterial consortia performed poorly in co-contaminated sites.…”

For decades human activities, industrialization and agriculture have contaminated soils and water with several compounds, including potentially toxic metals and organic persistent xenobiotics. The co-occurrence of those toxicants poses challenging environmental problems, as complicated chemical interactions and synergies can arise and lead to severe and toxic effects on organisms. The use of fungi, alone or with bacteria, for bioremediation purposes is a growing biotechnology with high potential in terms of cost-effectiveness, an environmentalfriendly perspective and feasibility, and often representing a sustainable nature-based solution. This paper reviews different ecological, metabolic and physiological aspects involved in fungal bioremediation of co-contaminated soils and water systems, not only addressing best methods and approaches to assess the simultaneous presence of metals and organic toxic compounds and their consequences on provided ecosystem services, but also the interactions between fungi and bacteria, in order to suggest further study directions in this field.
