“…radial growth rate or biomass production). The great variety of responses we observed among the different wood-rotting species agrees with other studies, where a great interspecific variability toward heavy metals has been detected in different fungal species, indeed, even differences in metal tolerance have occurred among isolates of a single species (intraspecific variability) (Collett 1992;Baldrian andGabriel 1997, 2002;Mandal et al 1998;Woodward and De Groot 1999;Baldrian 2003). This has been connected to the several detoxification mechanisms such as extra or intracellular precipitation and complexation, metal binding to cell walls and metal transformations developed by each fungal species or isolate (Gadd 1993;Baldrian 2003).…”

The effect of copper (II) ions on the growth of three brown-rot fungi, six white-rot fungi and one bluestain fungus in solid medium was evaluated. The fungi were grown in malt extract agar with different concentrations of copper added, and the radial growth rate was determined. At the end of the incubation period, the mycelial biomass and the media pH were determined. The white-rot and blue-stain fungus grew up to 3 mM and 6 mM copper, respectively and the brown-rot fungi were the only ones that grew up to 10 mM, with higher growth rates than those shown by the other fungi. In general, the brown-rot fungi produced greater acidification in the culture media than the white-rot fungi and blue-stain fungus, and the acidification increased when the amount of copper was increased. The biomass production for the different species, in the absence or presence of copper, was not related to the radial growth rate, and the fungal species that produced the greatest biomass amounts did not correspond to those that presented the highest growth rates. The brown-rot fungi Wolfiporia cocos and Laetiporus sulfureus and blue-stain fungus Ophiostoma sp. demonstrated greater tolerance to high copper concentrations in solid medium than the white-rot fungi, determined as radial growth rate. On the other hand, the highest biomass producers in solid medium with copper added were the white-rot fungi Ganoderma australe and Trametes versicolor and the brown-rot fungus Gloeophyllum trabeum.

“…Near motorways or industrial facilities, soil contamination with PAHs is often accompanied by the presence of high levels of heavy metals (26,31). Heavy metals like cadmium, copper, or mercury are known to be toxic for both white-rot fungi (3,40) and soil microflora (17) and their negative effect on the activity of ligninolytic enzymes has been described under in vitro conditions (4). The presence of these substances in the environment can therefore negatively influence the effectiveness of bioremediation technologies.…”

The white-rot fungus Pleurotus ostreatus was able to degrade the polycyclic aromatic hydrocarbons ( anthracene (41%), the fungus enhanced the disappearance of less-soluble polycyclic aromatic compounds containing five or six aromatic rings. Although the heavy metals in the soil affected the activity of ligninolytic enzymes produced by the fungus (laccase and Mn-dependent peroxidase), no decrease in PAH degradation was found in soil containing Cd or Hg at 10 to 100 ppm. In the presence of cadmium at 500 ppm in soil, degradation of PAHs by soil microflora was not affected whereas the contribution of fungus was negligible, probably due to the absence of Mn-dependent peroxidase activity. In the presence of Hg at 50 to 100 ppm or Cd at 100 to 500 ppm, the extent of soil colonization by the fungus was limited.

“…B = suelo contaminado con petróleo petróleo. Por su parte, Baldrían & Gabriel (1997) y Mandal et al (1998), señalan que los hidrocarburos aromáticos policíclicos (PAHs) a menudo están acompañados de la presencia de altas cantidades de metales pesados como cadmio, cobre o mercurio, tóxicos para los hongos que producen pudrición blanda y para la microbiota del suelo.…”
