“…Actually several fungi have attracted a growing interest for biotreatment of wastewater with different pollutants, such as metals, inorganic nutrients and organic compounds. Important results from fungi action can be seen in recent papers (Wesenberg et al 2003;Kaushik & Malik 2009;Gao et al 2010).…”

“…However, some of the research results have proven to be controversial; the discrepancy is based on enzymes actuation, which is attributed to their selective specificity concerning turn of the substrate (Lee 2007). Several authors agree that nitrogen-limitation increases ligninolytic activities through stimulation of LiP and MnP secretion (Van der Woude et al 1993;Gao et al 2008Gao et al , 2010. On the other hand, other results have shown that strains pre-grown on nitrogen-rich medium also exhibit enhanced decolourization rate (Adosinda et al 2001(Adosinda et al , 2002.…”

Enzyme production by immobilized Phanerochaete chrysosporium was evaluated in airlift bioreactor and agitated cultures. Free mycelium and immobilized mycelium on alginate beads were tested in the decolourization of 50 and 500 mg/L of Remazol Brilliant Blue R. Dye concentration did not inhibit the fungi development in all tests. In addition, high decolourization percentage of dye was found with free mycelium (99%) in agitated flasks and with immobilized mycelium in airlift (98%). However, decolourization period by immobilized mycelium (120 h) was greater than that by the free mycelium (14 h). Important manganese peroxidase, lignine peroxidase and laccase activities were identified in decolourization process. Manganese peroxidase appeared to be promoted by high dye concentrations during the treatment with immobilized mycelium, but this enzyme was not detected with free mycelium in airlift. Bioreactor prompted also laccase and lignine peroxidase actions in both tests; free mycelium registered a maximum laccase action of 31.569 × 10 3 U/L in 70 h, whereas immobilized mycelium registered 1.680 × 10 3 U/L in 170 h, while lignine peroxidase secretion by free P. chrysosporium was higher (1.300 × 10 3 U/L) than immobilized mycelium (1.250 × 10 3 U/L). Maximum laccase activity coincided with the maximum percentage of decolourization, however, high peroxidase activity was identified from the start of dye treatment.

“…In the 1980s, this fact stimulated research on the ability of ligninolytic fungi to degrade organic pollutants (Pointing, 2001;Gao et al, 2010). It was established that Phanerochaete chrysosporium is capable of biodegrading various pollutants and it soon became a model white-rot fungus with most of the research done up to now.…”

“…The hazards associated with PAHs can be overcome by the use of conventional physicochemical remediation methods; however, these are expensive, and in many cases, transfer the pollutant from one phase to another. Fungal degradation is often characterised as an environmentally friendly and costeffective approach to remove PAHs from soil (Bhatt et al 2002;Gao et al 2010). A number of species of ligninolytic fungi, such as Pleurotus ostreatus , are known to degrade PAHs and the biodegradation rates correlate with the production of ligninolytic enzymes (Bamforth and Singleton 2005;Johnsen et al 2005).…”

Influence of mixtures of acenaphthylene and benzo[a]anthracene on their degradation by Pleurotus ostreatus in sandy soil

Purpose Polycyclic aromatic hydrocarbons (PAHs) are a class of organic compounds commonly found as soil contaminants. Fungal degradation is considered as an environmentally friendly and cost-effective approach to remove PAHs from soil. Acenaphthylene (Ace) and Benzo[a]anthracene (BaA) are two PAHs that can coexist in soils; however, the influence of the presence of each other on their biodegradation has not been studied. The biodegradation of Ace and BaA, alone and in mixtures, by the white rot fungus Pleurotus ostreatus was studied in a sandy soil. Materials and methods Experimental microcosms containing soil spiked with different concentrations of Ace and BaA were inoculated with P. ostreatus. Initial (t 0 ) and final (after 15 days of incubation) soil concentrations of Ace and BaA were determined after extraction of the PAHs.Results and discussion P. ostreatus was able to degrade 57.7% of the Ace in soil spiked at 30 mg kg −1 dry soil and 65.8% of Ace in soil spiked at 60 mg kg −1 dry soil. The degradation efficiency of BaA by P. ostreatus was 86.7 and 77.4% in soil spiked with Ace at 30 and 60 mg kg −1 dry soil, respectively. After 15 days of incubation, there were no significant differences in Ace concentration between soil spiked with Ace and soil spiked with Ace + BaA, irrespective of the initial soil concentration of both PAHs. There were also no differences in BaA concentration between soil spiked with BaA and soil spiked with BaA + Ace. Conclusions The results indicate that the fungal degradation of Ace and BaA was not influenced by the presence of each other's PAH in sandy soil. Bioremediation of soils contaminated with Ace and BaA using P. ostreatus is a promising approach to eliminate these PAHs from the environment.
