“…It is worth to point out the high concentration of paraquat (200 mg/l) used for the solid medium experiments. Anasonye et al (2015) found that the growth of the fungi Phanerochaete chrysosporium was inhibited at concentrations of 24 ppm TNT when malt extract agar was used as a base medium. In 2005, Mukherjee and Mittal (Mukherjee and Mittal 2005), clearly identified inhibition of Aspergillus terreus and Cladosporium oxysporum, when exposed to the insecticide endosulfan at concentration of 100 µg/l.…”

Fifty-four macromycetes, isolated from southeastern Mexico, were used in order to evaluate their capacity for degradation and tolerance to the herbicide paraquat. Ten of these strains were capable of growing in a solid culture medium in the presence of 200 ppm paraquat. Subsequently, assays to evaluate the degradation of the xenobiotic in a liquid medium were carried out. Of the ten strains evaluated, three presented the highest levels of degradation of the compound, which were (54.2%), (54.1%) and They presented the highest overall degradation percentage (70.7%) after 12 days culture. The presence of ligninolytic enzymes in these strains was evaluated. only presented aryl alcohol oxidase activity; however, with the data obtained, it was not possible to conclude whether this specific enzyme is responsible for paraquat degradation. The level of degradation obtained is above the one reported for , one of the few reports on paraquat degradation. This is the first report on the contaminant degradation capacity of.

“…Lee et al (2009) conducted culture experiments with White-rot fungus (Irpex lacteus) and reported that the fungus degraded 95 % TNT after 48 h of incubation. White rot fungi (Phanerochaete velutina) was able to degrade 80 % of TNT in 2.5 months in a soil contaminated with TNT (Anasonye et al 2015). TNT was degraded by 79 % in 49 days in a further scale-up experiment with 0.3 tons of soil and an inoculum soil ratio of 1:30.…”

Environmental contextContaminants occur in the soil and water associated with military ranges. This review article describes how the extent of contamination depends not only on the type of military range and its period of activity, but also on the chemistry of both the soil and the contaminant. A full understanding of the soil chemistry is necessary to develop effective remediation methods for the restoration of these impacted environments. AbstractThis review discusses the contaminants associated with military ranges and the approaches taken to remediate these sites. The type and extent of contamination depends on the type of range, period of activity, soil chemistry and contaminant chemistry. Small arms firing ranges typically have high concentrations of metals and metalloids whereas military ranges typically have high concentrations of perchlorates, white phosphorus, explosives and propellants. For explosives, higher concentrations are found in sites that have undergone a low order detonation than in sites with a high order detonation. Remediation technologies for small arms firing ranges include leaching and immobilisation whereas for military ranges, methods such as alkaline hydrolysis, photolysis, bioremediation and phytoremediation have been tested. A lot of work has been done to immobilise metals/metalloids using soil amendments, which show a high effectiveness in stabilising them. Some of these amendments, however, also mobilise other co-contaminants. More studies are needed to simultaneously immobilise all inorganic contaminants. Explosives can be transformed into simpler non-toxic forms by photolysis, bioremediation or phytodegradation. The introduction of bacteria transgenes into plants has been used to enhance uptake and degradation of explosives in transgenic plants. Adoption of appropriate remediation technologies in impacted military ranges will reduce contaminant levels and protect public health.

“…The fungal species with FBCC number (isolation number is given in parenthesis) were: Agrocybe dura 478 (Mn71-2), Agrocybe praecox 476 (Tm70.84), Phanerochaete velutina 941 (T244i), Obba rivulosa 939 (T241i) (formerly known as Physisporinus rivulosus), Rhodocollybia butyracea 626 (K209) and Stropharia coronilla 480 (stock gram B). Fungal liquid cultures were prepared according to Anasonye et al (2015). Fungi were incubated on autoclaved Scots pine (Pinus sylvestris) bark, until the surface of the bark was fully covered with fungal mycelium.…”

The use of biochar (BC) has been suggested for remediation of contaminated soils. This study aims to investigate the role of microorganisms in sorption of PAH to BC-amended soils. Fungi, especially the wood and litter-degrading fungi, have shown the ability for humification and to degrade recalcitrant molecules, and are thus suitable model organisms. Haplic Arenosol with high organic matter content was chosen to highlight the importance of soil organic matter (SOM) in PAH sorption, possibly to form non-extractable residue. Basidiomycetous fungi Agrocybe praecox and Phanerochaete velutina grown on pine bark were inoculated in organic matter (OM) rich Haplic Arenosol and OM poor sandy loam with either BC or chemically activated BC (ABC) and 14 C-labelled pyrene for 60 days. Fungi did not mineralize pyrene, but increased sorption up to 47-56% in BC-amended Haplic Arenosol in comparison with controls (13-25%) without a fungus irrespective of the presence of an adsorbent. In OM poor sandy loam only 9-12% of pyrene was sorbed to amended soil in the presence of fungus and adsorbent. Combining BC and fungi is an effective method for sorbing pyrene especially in high SOM soils.
