“…All the treatments with 2 mg L −1 and 50 mg L −1 of Pb 2+ and Cd 2+ completely removed HMs, but treatment with EPP + 13 C + M1C3 only removed 84% of Pb 2+ , whereas EPP + 13 C + M2C3 showed a 78% Cd 2+ removal efficiency after 20 days of incubation ( Figure 3 a). Low efficiency was found for the treatments with 100 mg L −1 of HMs as due to higher metal concentration and the active sites of biofilms potentially being blocked due to fewer adsorption sites [ 41 ] and halting the continuous flow.…”

Priority pollutants such as polyethylene (PE) microplastic, lead (Pb2+), and cadmium (Cd2+) have attracted the interest of environmentalists due to their ubiquitous nature and toxicity to all forms of life. In this study, periphytic biofilms (epiphyton and epixylon) were used to bioremediate heavy metals (HMs) and to biodegrade PE under high (120,000 ppm) methane (CH4) doses. Both periphytic biofilms were actively involved in methane oxidation, HMs accumulation and PE degradation. Epiphyton and epixylon both completely removed Pb2+ and Cd2+ at concentrations of 2 mg L−1 and 50 mg L−1, respectively, but only partially removed these HMs at a relatively higher concentration (100 mg L−1). Treatment containing 12% 13CH4 proved to be most effective for biodegradation of PE. A synergistic effect of HMs and PE drastically changed microbial biota and methanotrophic communities. High-throughput 16S rRNA gene sequencing revealed that Cyanobacteria was the most abundant class, followed by Gammaproteobacteria and Alphaproteobacteria in all high-methane-dose treatments. DNA stable-isotope probing was used to label 13C in a methanotrophic community. A biomarker for methane-oxidizing bacteria, pmoA gene sequence of a 13C-labeled fraction, revealed that Methylobacter was most abundant in all high-methane-dose treatments compared to near atmospheric methane (NAM) treatment, followed by Methylococcus. Methylomonas, Methylocystis, Methylosinus, and Methylocella were also found to be increased by high doses of methane compared to NAM treatment. Overall, Cd+2 had a more determinantal effect on methanotrophic activity than Pb2+. Epiphyton proved to be more effective than epixylon in HMs removal and PE biodegradation. The findings proved that both epiphyton and epixylon can be used to bioremediate HMs and biodegrade PE as an efficient ecofriendly technique under high methane concentrations.

“…For instance, Tiwari et al [126] reported the current phytoremediation situation in India, where the availability of different phytoremediator trees is abundant, for example, Azadirachta indica, Acacia nilotica, Prosopis juliflora, Terminalia arjuna, Pongamia pinnata, and Eucalyptus tereticornis. Special interest is the use of Azaridachta indica and Acacia nilotica not only for their use in traditional medicine, personal care, and the presence of biologically active compounds [127] but also because of restoration of eroded soils and the phytoremediation potential, removing organic compounds [128,129], radionuclides [130], and toxic metals [122,131,132]. The studies report using seeds of A. indica from phytoremediation to produce ethanol from biomass fermentation and biodiesel via base-catalyzed transesterification.…”

Coupling Plant Biomass Derived from Phytoremediation of Potential Toxic-Metal-Polluted Soils to Bioenergy Production and High-Value by-Products—A Review

Phytoremediation is an attractive strategy for cleaning soils polluted with a wide spectrum of organic and inorganic toxic compounds. Among these pollutants, heavy metals have attracted global attention due to their negative effects on human health and terrestrial ecosystems. As a result of this, numerous studies have been carried out to elucidate the mechanisms involved in removal processes. These studies have employed many plant species that might be used for phytoremediation and the obtention of end bioproducts such as biofuels and biogas useful in combustion and heating. Phytotechnologies represent an attractive segment that is increasingly gaining attention worldwide due to their versatility, economic profitability, and environmental co-benefits such as erosion control and soil quality and functionality improvement. In this review, the process of valorizing biomass from phytoremediation is described; in addition, relevant experiments where polluted biomass is used as feedstock or bioenergy is produced via thermo- and biochemical conversion are analyzed. Besides, pretreatments of biomass to increase yields and treatments to control the transfer of metals to the environment are also mentioned. Finally, aspects related to the feasibility, benefits, risks, and gaps of converting toxic-metal-polluted biomass are discussed.

“…Environmental contamination has been increasing due to the rapid industrialization and anthropogenic activities leading to devastating impacts on terrestrial and aquatic ecosystems. It is well recognized that either human dependence on natural resources or worldwide industrial development has caused the water system exposure to the consecutive discharge of organic and inorganic pollutants (Lin et al, 2019;Saini et al, 2020). Heavy metals as one of the main environmental challenges have received much more attention over the decades because of their long-term persistence and toxicity in the low concentration, bioaccumulation potential, and neurotoxic and carcinogenic effects (Rahman et al, 2019;Riskuwa-Shehu et al, 2019).…”

“…Many works of literature have highlighted the critical potential risk of heavy metals influenced the entire eco-environment via fossil fuel combustion, mining residues, electroplating, fertilizers, and pesticides (Chu & Phang, 2019;Xu et al, 2020;Yan et al, 2020). Toxic heavy metals can seriously accumulate in various tissues posing gastrointestinal damages, mutagenicity, and mental retardation (Saini et al, 2020;Zhang et al, 2019). Therefore, the applicable approaches should be taken into account to preserve the environment.…”

“…Different methods have been developed for the heavy metal removal comprising ion exchange, biosorption, chemical precipitation, oxidation, reduction, filtration, and coagulation (Fan et al, 2017;Ihsanullah et al, 2016;Nemati et al, 2017;Saini et al, 2020). These technologies usually cause high operational costs, low efficiency, and secondary pollution, and they are not well-organized for large-scale water treatment (Chu & Phang, 2019;Qin et al, 2020).…”

Since heavy metals have been regarded as ubiquitous environmental pollutants, the exploitation of bacterial biosorption has been suggested as an applicable method for being employed for heavy metal depletion. The present study aimed to characterize the function of Lactobacillus paracasei in the presence of Pb (II) and Cd (II). The simultaneous effect of pH, initial metal concentration, and inoculum size demonstrated the Pb (II) removal of 85.77% at the lowest pH, while the inoculum size was enhanced to 45 CFU/100 ml. The maximum Cd (II) removal was obtained at a high level of pH and inoculum size, while the metal concentration was reduced to 30 ppb. The addition of Cd (II) concentration in access led to the 10% drop in Cd (II) removal efficiency attributed to the metal toxicity and pH. Additionally, the slight variation in the amount of inoculum size caused the decreasing trend in the Cd (II) removal. According to the obtained results, the benefit of L. paracasei in the biosorption of heavy metals was well-recognized, which could be suggested as an alternative candidate. © 2021 Water Environment Federation • Practitioner points• Strain of Lactobacillus paracasei as potential probiotics was tested for biosorption. • A successful response surface method was proposed. • L. paracasei showed a good efficiency for the lead and cadmium biosorption.• Biosorption process was effective in removing low metal level from drinking water. • The maximum biosorption was found to be 85.77% for Pb (II) obtained from the experiment.
