Phytoremediation of petroleum-polluted soils: Application of Polygonum aviculare and its root-associated (penetrated) fungal strains for bioremediation of petroleum-polluted soils

A nonpathogenic Fusarium oxysporum strain enhances phytoextraction of heavy metals by the hyperaccumulator Sedum alfredii Hance

“…Diverse biochemical and ecological activities of F. oxysporum fungi are being explored [44][45][46]. A recent study showed that petroleum-resistant F. oxysporum fungi and other Fusarium fungi could efficiently remediate petroleum-polluted soils together with plants [47]. Our study for the first time showed that a metalresistant nonpathogenic F. oxysporum fungus promoted metal phytoextraction by a hyperaccumulator.…”

Can ornamental potted plants remove volatile organic compounds from indoor air? — a review

“…Mycorrhizal fungi are equally important as bacteria for the mineralization of pollutants (Bouwer and Zehnder 1993). Arbuscular mychorrhizal fungal hyphae have been found to translocate fluorene and phenanthrene to roots of Lolium multiflorum (Gao et al 2010a) and in a remediation study of petroleum-polluted soil, Polygonum aviculare and its root-associated fungal strains were more effective in remediation of the soil than the plant or fungi alone (Mohsenzadeh et al 2010). Several studies have shown that the action of microorganisms can be enhanced when a plant is present (Wood et al 2002;Xu et al 2010Xu et al , 2013.…”

Selection of forest species for the rehabilitation of disturbed soils in oil fields in the Ecuadorian Amazon

“…One of the distinctive characteristics of petroleum-contaminated soils is their poor aeration, which affects microbe processes and soil microelement contents. For this reason, bioremediation techniques usually begin by trying to improve aeration; plant roots play a key role in accelerating such soil aeration improvement (Mohsenzadeh et al, 2010), which may have also occurred at the sites surveyed by this study following two years of vegetation growth. The concentrations of TPH in Cells and CSTU sites were higher than permissible at the beginning and end of the experiment (MAE, 2001).…”

“…At a global level, some studies have been carried out to select plant species for soils disturbed by petroleum extraction activities, and to assess the effects of these species on soil characteristics in tropical and subtropical ecosystems (e.g., McConkey et al, 2012 andWillis et al, 2005 in America and Mohsenzadeh et al, 2010;Shirdam et al, 2008 andXia, 2004 in Asia). However, as far as we know there are no such studies in the Amazon Basin.…”
