Abstract Coupling of power-to-gas processes with underground gas storage could effectively allow surplus electricity to be stored for later use. Depleted hydrocarbon reservoirs used as stores, but practical experience hydrogen in such sites is limited. Here we present data from a field trial that 119,353 m 3 admixed natural depleted reservoir. After 285 days, recovery was 84.3%, indicating the process’s technical feasibility. Additionally, report microbes mediated conversion methane. In...
Mycotoxins are secondary metabolites of fungi affecting human and animal health. Five classes mycotoxins major concern in husbandry, namely aflatoxins, trichothecenes, zearalenone, ochratoxins, fumonisins. Due to their diverse structure these fungal toxins able cause a great variety acute symptoms animals. Clay minerals have been used nutrition bind mycotoxins, but the binders only very specific for aflatoxins not other toxins. A novel strategy control problem mycotoxicoses animals is...
Phytoremediation of soils polluted with polycyclic aromatic hydrocarbons (PAHs) has so far neglected the possible role ubiquitous symbiotic associations between plant roots and fungi known as arbuscular mycorrhizas. A time course laboratory experiment clover ryegrass grown on spiked [500 + 500 50 mg kg-1 anthracene, chrysene dibenz(a,h)anthracene] soil demonstrated for first that dissipation condensed PAHs may be enhanced in presence mycorrhiza [66 42% reductions dibenz(a,h)anthracene,...
Abstract Hazard assessment of industrial sites contaminated with coal tar and its products usually focuses on selected pollutants such as the 16 polycyclic aromatic hydrocarbons (PAHs) prioritized by U.S. Environmental Protection Agency (U.S. EPA). The aim this study was to investigate which extent these PAHs contribute Vibrio fischeri bioluminescence inhibition measured acute Lumistox® luminescent bacteria test. Five PAHs—naphthalene(NA), acenaphthylene (ACY), acenaphthene (ACE), fluorene...
To assess the exposure to polycyclic aromatic hydrocarbons (PAHs) it is important understand binding mechanisms between specific soil constituents and organic pollutant. In this study, sorptive bioaccessibility extraction (SBE) was applied quantify accessible PAH fraction in industrially contaminated with without passive dosing of a competitive sorbate. SBE experiments revealed an 41 ± 1% (∑16 US EPA PAHs + 5 further PAHs). The toluene below its saturation level resulted average increase 49...
A simplified sample pretreatment method for industrially PAH-contaminated soils applying automated Soxhlet (Soxtherm) with ethyl acetate as extraction solvent is presented. Laborious steps such drying of samples, cleanup crude extracts, and exchange were allowed to be bypassed without notable performance impact. Moisture the soil samples did not significantly influence recoveries PAHs at a wide range water content newly developed method. However, opposite was true standard procedure using...
Laccases (EC1.10.3.2) have attracted growing attention in bioremediation research due to their high reactivity and substrate versatility. In this study, three genes for potential novel laccases were identified an enrichment culture from contaminated field soil recombinantly expressed E. coli. Two of them, designated as PlL BaL, biochemically characterized regarding optimal pH temperature, kinetic parameters, addition, lacasse Parvibaculum lavamentivorans was tested on historically soil....
Bioremediation of contaminated soils often leaves a desorption-resistant pollutant fraction behind in the soil, which present study was isolated with combination diffusive carrier and infinite sink. Such sink made by casting composite silicone activated carbon into bottom large glass. Field-contaminated soil samples were then suspended cyclodextrin solution incubated such glasses for continuous trapping PAH molecules during their release from matrix. The concentrations remaining determined...
Abstract Accumulation of microbial biomass and its influence on porous media flow were investigated under saturated conditions. Microfluidic experiments performed with model organisms, their accumulation was observed in the pore space sub-pore scale. Time-lapse optical imaging revealed different modes through primary colonization, secondary growth, filtration events, showing formation preferential pathways flooding domain as result increasing interstitial velocity. Navier–Stokes–Brinkmann...
This laboratory study investigates the potential of two innovative laccase-mediator systems for removing PAHs from historically contaminated field soil and focuses on treatment effect accessible desorption resistant PAH fraction. Laccase degraded when applied in combination with mediator TEMPO (up to 24 % within 48 h). The HBT did not induce degradation but mobilized high affinity sorption sites via a competitive mechanism. Enzymatic inaccessible was observed neither enzyme-mediator systems....
Abstract BACKGROUND: Bioaccessibility is often the limiting factor for biodegradation of polycyclic aromatic hydrocarbons (PAH) in soils. The present study explores potential amending canola oil, an economically and ecologically attractive soil additive, enhancement bioaccessibility and, consequence, PAH historically contaminated, limited RESULTS: amendment oil (1% 5%, w/w) to contaminated soils increased subsequent with up four rings. Residual concentrations pyrene fluoranthene oil‐treated...
