“…In this study, the potential removal ability observed in the soil assisted with the vermicompost and PGPB may be as a result of the presence of microbes that enhanced the plant growth (Hassan et al 2020). However, the removal of this metals observed in this work looked similar to that cited by Achal et al (2011) (94 %) but lower than that obtained with M. o cinalis L. on Angwan Magiro soil.…”

This research was designed to clean-up through an environmentally friendly techniques, a polluted environment of Madaka District of Shikira. Physicochemical properties of the soil were done using standard methods. Chicken dropping vermicompost (CDV) and goat manure vermicompost (GMV) were produced by standard method to assist the phytoremediation process with plant growth promoting bacteria (PGPB). Canonical discriminant functions of the heavy metals were done. For the first location (AK) the plant parts of M. officinalis L mopped up heavy metals, the concentration of Cd, As, Pb in plant parts varied from 0.007 to 0.33 mg/kg, As from 0.09 to 4.39 mg/ kg and Pb from 0.07 to 10.35 mg/kg respectively while the concentration of heavy metals in S. acuta parts had Cd, As, Pb varied from 0.002 to 0.43 mg/kg, As from 0.27 to 3.79 mg/ kg and Pb from 1.68 to 10.7 mg/kg respectively. The second location (AM) also had the two plants mopping up heavy metals at different concentrations. the concentration of Cd, As, Pb in M. officinalis L parts varied from 0.03 to 0.41 mg/kg, As from 0.65 to 4.65 mg/ kg and Pb from 1.93 to 11.49 mg/kg respectively while the concentration of heavy metals in S. acuta parts had Cd, As, Pb varied from 0.06 to 0.66 mg/kg, As from 0.68 to 4.64 mg/ kg and Pb from 1.53 to 11.53 mg/kg respectively. Melissa offinalis L and Sida acuta were found most suitable for phytoextraction of sites contaminated with Cd, As and Pb because both of them have their bioconcentration factor (BCF), translocation factor (TF) and biological accumulation coefficient (BAC) to be ˃1 while both were also scored as phytostabilizer because they have BCF ˃1 and TF ˂1. Soil structural changes pre and post remediation were determined through x-ray fluorescence (XRF spectroscopy) and scanning electron microscopy (SEM) analyses.

“…Their bioremediation potential has been recently explored, i.e., HMs removal capacity from single/multi-metal solutions or contaminated soil bioaugmented with fungal consortia, and their ability to assist in phytoremediation of HM-contaminated soil [ 24 , 31 , 32 , 43 , 44 , 86 , 87 , 88 ]. Unique fungal diversity was identified in various HM-contaminated sites [ 24 , 31 , 43 , 44 , 87 , 88 ]. Similar investigations on bacterial populations reflect the same results [ 56 , 89 , 90 , 91 ].…”

“…Metalresistant fungi, autochthonous to contaminated soils, show remarkable degrees of resistance towards HMs. Their bioremediation potential has been recently explored, i.e., HMs removal capacity from single/multi-metal solutions or contaminated soil bioaugmented with fungal consortia, and their ability to assist in phytoremediation of HM-contaminated soil [24,31,32,43,44,[86][87][88]. Unique fungal diversity was identified in various HM-contaminated sites [24,31,43,44,87,88].…”

“…Therefore, identifying low cost and less invasive technologies is necessary for addressing the remediation of HM-contaminated sites. In situ bioremediation approaches, i.e., biostimulation, biosparging, bioventing, and bioaugmentation [ 24 , 25 , 26 ], or microorganisms-assisted phytoremediation [ 27 , 28 , 29 ], have been recently considered for the decontamination of HMs contaminated soils. The use of bioremediation technologies can prevent secondary HMs dispersal and unnecessary human exposure can be avoided.…”

“…The advantages are obvious: these isolates are already adapted to site-specific conditions, especially to competition within local communities, and are equipped with resistance/tolerance mechanisms that may account for toxicity reduction or removal of HMs at the site [ 31 , 42 , 43 , 44 ]. Lab-scale and greenhouse experiments validate soil HM mycoremediation performance [ 24 , 31 , 39 ]. Similarly, effective recovery of HMs from contaminated water by fungi as biosorbents has also been demonstrated at small-scales [ 45 , 46 , 47 , 48 ].…”

Filamentous fungi native to heavy metals (HMs) contaminated sites have great potential for bioremediation, yet are still often underexploited. This research aimed to assess the HMs resistance and Hg remediation capacity of fungi isolated from the rhizosphere of plants resident on highly Hg-contaminated substrate. Analysis of Hg, Pb, Cu, Zn, and Cd concentrations by X-ray spectrometry generated the ecological risk of the rhizosphere soil. A total of 32 HM-resistant fungal isolates were molecularly identified. Their resistance spectrum for the investigated elements was characterized by tolerance indices (TIs) and minimum inhibitory concentrations (MICs). Clustering analysis of TIs was coupled with isolates’ phylogeny to evaluate HMs resistance patterns. The bioremediation potential of five isolates’ live biomasses, in 100 mg/L Hg2+ aqueous solution over 48 h at 120 r/min, was quantified by atomic absorption spectrometry. New species or genera that were previously unrelated to Hg-contaminated substrates were identified. Ascomycota representatives were common, diverse, and exhibited varied HMs resistance spectra, especially towards the elements with ecological risk, in contrast to Mucoromycota-recovered isolates. HMs resistance patterns were similar within phylogenetically related clades, although isolate specific resistance occurred. Cladosporium sp., Didymella glomerata, Fusarium oxysporum, Phoma costaricensis, and Sarocladium kiliense isolates displayed very high MIC (mg/L) for Hg (140–200), in addition to Pb (1568), Cu (381), Zn (2092–2353), or Cd (337). The Hg biosorption capacity of these highly Hg-resistant species ranged from 33.8 to 54.9 mg/g dry weight, with a removal capacity from 47% to 97%. Thus, the fungi identified herein showed great potential as bioremediators for highly Hg-contaminated aqueous substrates.
