Anaerobic digestion (AD) is a waste-to-energy strategy that leverages natural microbiological processes. It increasingly used in farms to treat manure, resulting biogas for energy production and digestate as fertiliser. However, animal manure often contains antibiotic (AB) residues, raising concerns about their impact on AD efficiency potential spread through use. This multidisciplinary study evaluated the effects of an AB mixture (enrofloxacin, ciprofloxacin sulfamethoxazole) CH4...
Pollutants in soils are detrimental to ecosystems and agricultural production may also be a pressing threat human health. In this context, biochar could used as part of nature-based solutions remediate polluted areas. work, series innovative biochar-based strategies were tested soil contaminated by hydrocarbons C > 12 copper (Cu) investigate their effectiveness decontamination revegetation potential. Specifically, was applied alone (SB) or combined with bioaugmentation (SBB) and/or...
Anaerobic digestion (AD) treatment of cattle manure and slurry makes it possible to produce biogas, a renewable storable biofuel, as well digestate, residual organic matter that can be used replace chemical fertilizers. On the other hand, intense use antibiotics (e.g., sulfamethoxazole) in animal husbandry practices is showing increasing negative impacts resulting from release still metabolically active molecules into agroecosystems. In present study, collected an AD plant-feeding tank was...
Due to their widespread use in industrial applications recent decades, Polychlorobiphenyls (PCBs) and heavy metals (HMs) are the most common soil contaminants worldwide, posing a risk for both ecosystems human health. In this study, poplar-assisted bioremediation strategy has been applied more than 4 years historically contaminated area (PCBs HMs) Southern Italy using Monviso poplar clone. This clone was effective promoting decrease all an increase quality terms of organic carbon microbial...
A Monviso clone has been applied to promote PCB degradation in a soil historically contaminated by polychlorinated biphenyls (PCBs) and heavy metals (HMs). The multi-contaminated area is located Southern Italy. PCBs, HMs, the microbial community (abundance, viability, structure) were analysed selected plots of poplar-treated area. At 900 days after poplar planting, chemical analyses showed that PCBs most HMs diminished under Italian legal limits. overall results suggest was effective...
Abstract Purpose The present work aimed to fill some knowledge gaps on the effects non-target natural soil microbial communities of sulfamethoxazole (SMX) antibiotic potentially found in cattle manure digestate. Both prokaryotic and fungal community under different conditions were analyzed using molecular ecology methods. Methods A previous microcosm experiment with a amended digestate (3% dry mass) spiked SMX (20 mg/kg soil) was used for this in-depth study. Microbial live cell abundances...
Some livestock farms rely on anaerobic digestion (AD) technology for manure disposal, thus obtaining energy (biogas) and fertilizer (digestate). Mixtures of antibiotics used animal health often occur in organic waste their possible synergistic/antagonistic effects microorganisms involved AD are still poorly studied. This work focuses the adding ciprofloxacin, alone (5 mg L
The effectiveness of adding compost and the plant Medicago sativa in improving quality a soil historically contaminated by polychlorinated biphenyls (PCBs) was tested greenhouse microcosms. Plant pots, containing samples from an area PCBs, were treated with plant, separately or together. Moreover, un-treated un-planted microcosms used as controls. At fixed times (1, 133 224 days), PCBs analysed structure (cell abundance, phylogenetic characterization) functioning viability, dehydrogenase...
Microbial Fuel Cells (MFCs) transform organic matter into electricity through microbial electrochemical reactions catalysed on anodic and cathodic half-cells. Terrestrial MFCs (TMFCs) are a bioelectrochemical system for bioelectricity production as well soil remediation. In TMFCs, the is ion-exchange electrolyte, whereas biofilm anode oxidises electroactive bacteria. Little known of overall community composition in TMFC, which impedes complete exploitation potential to generate energy...
There are several tunnelling projects underway in Europe and worldwide to facilitate connections between distant areas or ones with geographical constraints (e.g. mountains). As a result, the tunnel industry has been producing huge amounts of excavated material (spoil material: SM), which can be re-used for different purposes (including green areas). Adding lime practical procedure at construction site stabilization SM makes it possible manage better its final destination site. This work...
The electrical performance of Terrestrial Microbial Fuel Cells (TMFCs) with soil as the electrolyte was tested two concentrations (150 or 250 ng/g soil) PCBs (Polychlorinated biphenlys) and compost (3 % w/w) in an experiment lasting 60–80 days. Energy output levels were recorded daily by varying external resistance for detecting best operating conditions. PCB microbiological analyses (total microbial abundance activity) performed at start end experiment. highest power generation (207 ± 80...
Fagus sylvatica L. is widely distributed across Europe thanks to its high adaptability in a wide variety of soils and climate. Microbial communities are essential for maintaining forest soil quality responsible ecosystem functioning; the ability microorganisms respond abiotic stressors (e.g., organic carbon losses, water scarcity, temperature changes) crucial under ongoing environmental changes also supports tree health. In this study, samples were collected from pure beech plots as part...
The anionic surfactant Sodium Lauryl Ether Sulfate (SLES) is the principal component of several commercial foaming products for soil conditioning in tunneling industry. Huge amounts spoil material are produced during excavation process and presence SLES can affect its re-use as a by-product. Anionic surfactants be risk ecosystems if occurring environment at toxic concentrations. biodegradability key issue excavated to reused. aim this study was identify bacteria able degrade SLES, so that it...
In contaminated dredged sediments, organic and persistent contaminants (e.g. Polycyclic Aromatic Hydrocarbons, PAHs; Total Petroleum TPH) can accumulate. Here, microbial fuel cells (MFCs) were set-up using a river sediment containing PAHs, TPHs heavy metals. Electrical open closed-circuit conditions used, polarization curves recorded. MFCs assembled with compost (3%) to demonstrate its beneficial effect on community. The MFC activation time was relatively low, probably thanks the community...
Cattle manure or its digestate, which often contains antibiotic residues, can be used as an organic fertilizer and copper (Cu) a fungicide in agriculture. Consequently, both antibiotics Cu are considered soil contaminants. In this work, microcosms were performed with amended either digestate (sulfamethoxazole, SMX) co-presence the planting of Lactuca sativa. After addition amendments, prompt increase microbial activity at same time sul1 intI1 genes was observed, although ARGs generally...
The anionic surfactant sodium lauryl ether sulfate (SLES) is the main component of most commercial foaming agents (FAs) used in excavation highway and railway tunnels with Earth pressure balance-tunnel boring machines (EPB-TBMs). Several hundreds millions tons spoil material, consisting soil mixed FAs, are produced worldwide, raising issue their handling safe disposal. Reducing waste production reusing by-products primary objectives “circular economy,” this context, biodegradation SLES...
This work studied the combined effects of antibiotics (ABs) frequently found in cattle manure on anaerobic digestion (AD) process. AB persistence and antibiotic resistance genes (ARGs) occurrence were evaluated. For this purpose, a batch experiments was set up using mixture digestate simulating substrate composition inside full-scale reactor (ratio 1:35, respectively). Enrofloxacin added alone (ENR: 7.5 mg kg-1), or mixed with equal amounts sulfamethoxazole (SMX) ciprofloxacin (CIP) at low...
