“…The loading scores of bacterial (Figure d) and fungal (Figure f) abundance at the genus level were displayed to screen out the most important variables (biomarkers) in response to the ONBC amendment. The most important biomarkers were almost aerobic, including bacteria for nitrifying or nitrosifying ( Rhodopseudomonas and Nitrosomonas ), aerobic organic matter degradation ( Acinetobacter , Cellulomonas , Luteolibacter ), , tolerance to oxidative stress ( Ramlibacter ), and Cu binding ( Psudomonas and Sphingomonas ), in regard to the bacterial community. The most important biomarkers responding to the control without the oxygen nanobubble amendment were strictly or facultatively anaerobic, including bacteria for N 2 fixation ( Azospira, Devosia , and Paenibacillus ), anaerobic organic matter degradation ( Lautropia , Terrisporobacter , Rhodopseudomonas and Muribaculaceae ), , sulfur oxidation ( Thiobacillus ), and methanogensis and denitrification ( Geobacter ) .…”

“…The ONBC treatments improved the microbial richness and diversity (Figure S5), which might include the Cu-binding microbial species. The bacterial biomarkers responding to the ONBC treatment include Psudomonas and Sphingomonas, which contain many Cu-binding species 42 and may elucidate the increased abundance of genes involved in Cu stabilization.…”

Copper (Cu)-contaminated paddy soil has caused substantial concerns for human health through biomagnification in the soil–rice–human chain. In this study, oxygen nanobubble-loaded biochars (ONBC), including pyrochars (NPC) and hydrochars (NHC), were used to amend Cu-contaminated paddy soils and reduce rice Cu toxicity. The ONBC amendment improved the rhizospheric redox potential and dissolved oxygen concentration via slow, continuous oxygen release, promoting root iron plaque formation and effectively inhibiting root Cu influx. Moreover, the ONBC amendment improved soil microbial diversity. The abundance of bacterial genes involved in cytosolic Cu complexation and Cu export to the periplasm space for Cu stabilization markedly improved. The sequestered Cu in root iron plaque and soil bacteria inhibited Cu influx into the shoots to avoid Cu overaccumulation in the edible parts. This was reflected by the Cu content decreasing by 1.91-fold and 2.38-fold in shoots under NPC and NHC treatments, respectively. Furthermore, the improved oxygen-enriched rhizosphere environment via the ONBC amendment promoted root activity and the abundance of bacterial genes involved in nutrients mineralization, further promoting shoot biomass by 1.46-fold and 2.29-fold under NPC and NHC treatments, respectively. This study proposes an environmentally friendly strategy to mitigate Cu transfer from soil to crops and improve crop productivity.

“…First, the reduction of Cu 2+ to Cu 2 O (CrO 4 2− to Cr(OH) 3 ) may be due to the significant difference of the redox potentials between the acceptor and donor systems. Really, the acceptor systems (the metals) have very high values of potentials (i.e., E 0 = +486 mV of Cu 2+ and E 0 = +555 mV of CrO 4 2− ), and strict anaerobes create very low redox potentials, such as −200 ÷ −300 mV [26,49]. Second, the accumulation of metals inside a microbial cells also takes place due to the stereochemical analogy with macroelements [50].…”

The accumulation of various types of waste containing both organic and inorganic metal-containing compounds is extremely hazardous for living organisms. The possibility of polymer degradation, biohydrogen synthesis, and metal detoxification via the dark fermentation of model potato waste was investigated. For this purpose, the strict anaerobic strain was isolated and identified as Clostridium butyricum. The high efficiency of dark hydrogen fermentation of potatoes with yield of hydrogen in 85.8 ± 15.3 L kg−1 VSpotato was observed. The copperand chromium salts solutions were added to the culture fluid to obtain the concentrations of 50, 100, and 200 mg L−1 Cu(II) and Cr(VI) in the active phase of growth (19 h of cultivation). Metals at a concentration of 200 mg L−1 inhibited the fermentation process the most. The hydrogen yield decreased in 7.2 and 3.6 times to 11.9 ± 2.1 and 23.8 ± 5.6 L kg−1 VSpotato in the presence of 200 mg L−1 Cu(II) and Cr(VI), respectively. The efficiencies of the chromium bioremoval in all variants of the experiment were 100%, and those of copper bioremoval were about 90%. A pure culture of strict anaerobes Clostridium butyricum strain 92 was used for the first time for the detoxification of metals. The presented results confirmed the possibility of this promising strain application for industrial H2 production and the bioremediation of contaminated sites.

“…Therefore, the development of methods for the simultaneous utilization of ecologically hazardous invasive plants, the synthesis of biogas, and the detoxification of metals is a promising scientific approach. These methods also require the isolation of promising metal-resistant microbial strains or microbial communities capable of copper detoxification [ 39 ].…”

The weed Solidago canadensis L. poses a global threat to the environment as it spreads uncontrollably on roadsides, in forests, fields, meadows, and farmland. Goldenrod emits toxic substances that suppress other plants on the site, displacing wild ones. Thus, goldenrod conquers huge areas very quickly. The use of herbicides and mechanical methods does not solve the problem of the spontaneous spread of goldenrod. On the other hand, many scientists consider goldenrod as a valuable source of biologically active substances: flavonoids, phenolic compounds, vitamins, etc. In this study, we consider Solidago plants as a promising, free (cheap), and renewable substrate for the production of methane gas. The goal of the study was to identify the main patterns of degradation of the Solidago canadensis L. plant by methane-producing and sulfate-reducing bacteria with methane gas production and simultaneous detoxification of toxic copper. The composition of the gas phase was monitored by gas chromatography. The pH and redox potential parameters were determined potentiometrically; metal concentrations were measured by photometry. The concentration of flavonoids, sugars and phenolic compounds in plant biomass was determined according to well-known protocols. As a result of the study, high efficiencies of methane degradation in the Solidago plant and copper detoxification were obtained. Methane yield has reached the value of 68.2 L kg−1 TS of Solidago canadensis L. biomass. The degradation coefficient (Kd) was also high at 21.4. The Cu(II) was effectively immobilized by methanogens and sulfate reducers during the goldenrod degradation at the initial concentrations of 500 mg L−1. Thus, a new method of beneficial application of invasive plants was presented. The result confirms the possibility of using methanogenic microorganisms to produce methane gas from invasive weeds and detoxification of toxic metals.
