“…A. bisporus, F. velutipes), accumulate it at levels largely exceeding allowance thresholds, with no changes in macronutrient composition [28,46]. In turn, yield of other species such as G. lucidum can be significantly altered with increasing Hg content in overgrown substrate [47].…”

There is an ongoing interest in the production of mushrooms as food, and with their consumption on the rise, there is a need to establish different safety measures. In the present study, six mushroom species (Agrocybe cylindracea, Clitocybe maxima, Flammulina velutipes, Ganoderma lucidum, Lentinula edodes and Pleurotus eryngii) were cultivated on two commonly used substrates (A-based on alder and beech sawdust; B-based on oak sawdust and flax shives). The aims were to determine their growth and the accumulation of 70 elements in their fruiting bodies, 33 of which were detected in all analysed samples and were used for statistical evaluation. Cultivation of C. maxima, G. lucidum and L. edodes resulted in higher yield and mineral content when substrate A was used, cultivation of A. cylindracea and F. velutipes yielded better results on substrate B, P. eryngii cultivation outcomes were similar for both substrates. L. edodes was found to have a high affinity to accumulate Cd, C. maxima can bioconcentrate Al and Ni, Ganoderma lucidum-Pb, while F. velutipes-Hg. The study indicated that the chemical composition of substrates could affect both the yield and the level of various toxic and nutritional elements.

“…Recently, Cd II has been reported to inhibit the oxidation of 3‐dimethylaminobenzoic acid, poly R, and polycyclic aromatic hydrocarbons [30,31] by the unpurified extracellular fluids of the white‐rot fungi P. chrysosporium and Pleurotus ostreatus . However, Cd II also inhibits fungal growth [31,32] and may affect extracellular enzyme levels. Herein, we report the results of steady‐state and transient‐state kinetic experiments on the inhibition of purified manganese peroxidase by Cd II .…”

“…The Ganoderma genus has been reported for its tolerance to metals in the culture medium, among them copper (Tham et al 1999;Baldrian 2003;Guillén and Machuca 2008); to our knowledge, however, there is no information in the literature that mentions the behavior of G. australe with respect to copper-based or boron-silicon-based wood preservatives, be it in in vitro tests, as conducted here, or in tests using preserved wood. However, there are data that reveal the ability of G. australe A464 to degrade 2,4,6-tribromophenol (TBP) in liquid culture medium, a much greater degradation than that produced by the BRF G. trabeum and Laetiporus sulfureus (Monrroy et al 2006(Monrroy et al , 2007.…”

Tolerance to wood preservatives by copper-tolerant wood-rot fungi native to south-central Chile

Understanding the effect of heavy metals and wood preservatives on the growth of wood-rot fungi native to a certain region may improve reliability in determining the effectiveness of antifungal products, particularly when dealing with new formulations. In this investigation, strains of copper-tolerant wood-rot fungi native to south-central Chile were evaluated against two preservatives: commercial chromated copper arsenate type C (CCA-C) and a new formulation with boron and silicon (BS). Thirteen native strains, mainly white-rot fungi, were selected for their high growth rates in solid medium containing 3 mM of copper. A short-term test was then carried out, consisting of adding cellulose disks impregnated with different concentrations of preservatives to solid culture media inoculated with selected copper tolerant strains. There was a great variability in interspecific and intraspecific responses to the presence of copper and preservatives in culture media. Among the native and commercial strains evaluated, the white-rot fungi Trametes versicolor 38 and mainly Ganoderma australe 100 were notable for their tolerance to all the CCA-C and BS concentrations. The brown-rot fungus Wolfiporia cocos, used as reference strain, showed a high tolerance to CCA-C, but not to BS preservative. T. versicolor 38 and G. australe 100 were selected for subsequent studies on preserved wood degradation.
