Assessment of the effects of oxamyl on the bacterial community of an agricultural soil exhibiting enhanced biodegradation
(2019)Modern agricultural practices largely rely on pesticides to protect crops against various pests and to ensure high yields. Following their application to crops a large amount of pesticides ends up in soil where they may ... -
Biodegradation of anthelmintics in soils: does prior exposure of soils to anthelmintics accelerate their dissipation?
(2022)Anthelmintics (AHs) control animal infections with gastrointestinal nematodes. They reach soil through animal faeces deposited on soils or through manuring. Although soil constitutes a major AH sink, we know little about ... -
Blame it on the metabolite: 3,5-dichloroaniline rather than the parent compound is responsible for the decreasing diversity and function of soil microorganisms
(2018)Pesticides are key stressors of soil microorganisms with reciprocal effects on ecosystem functioning. These effects have been mainly attributed to the parent compounds, while the impact of their transformation products ... -
Challenges in microbially and chelate-assisted phytoextraction of cadmium and lead – A review
(2021)Cadmium (Cd) and lead (Pb) are ubiquitously present in surface soils, due to anthropogenic activities, causing threat to ecological and human health because of their carcinogenic nature. They accumulate in large quantities ... -
The dissipation of fipronil, chlorpyrifos, fosthiazate and ethoprophos in soils from potato monoculture areas: First evidence for the enhanced biodegradation of fosthiazate
(2016)BACKGROUND: A limited number of pesticides are available for the control of soil pests in potato. This, together with the monoculture nature of potato cultivation, does not favour chemical rotation, increasing the risk of ... -
Dissipation of pure and broccoli-released glucosinolates in soil under high and low moisture content
(2013)Glucosinolates (GSLs) are secondary metabolites found in Brassica species. Upon tissue disruption GSLs are hydrolyzed by myrosinase enzymes to isothiocyanates (ITCs) which are highly toxic to microbes. Therefore the ... -
Effects of organic loading rate and hydraulic retention time on bioaugmentation performance to tackle ammonia inhibition in anaerobic digestion
(2021)Three continuously stirred-tank reactors fed with manure operating under high ammonia levels (5.0 g NH3-N L−1) and with increased organic loading rate (OLR), (2.09 R1, 3.02 R2 and 4.0 R3 g VS L−1 d−1), achieved through ... -
Effects of sheep bone biochar on soil quality, maize growth, and fractionation and phytoavailability of Cd and Zn in a mining-contaminated soil
(2021)Biochar prepared from various feedstock materials has been utilized in recent years as a potential stabilizing agent for heavy metals in smelter-contaminated soils. However, the effectiveness of animal bone-derived biochar ... -
Effects of the nitrification inhibitor 3,4-dimethylpyrazole phosphate (DMPP) on the activity and diversity of the soil microbial community under contrasting soil pH
(2021)The impact of DMPP (3,4-dimethylpyrazole phosphate), applied at two doses (low: recommended for agronomic use; high: > 100 × the recommended), on the function, diversity, and dynamics of target microorganisms (ammonia-oxidizing ... -
Gene expression profiling of microbial activities and interactions in sediments under haloclines of E. Mediterranean deep hypersaline anoxic basins
(2016)Deep-sea hypersaline anoxic basins (DHABs) in the Eastern Mediterranean Sea are considered some of the most polyextreme habitats on Earth. In comparison to microbial activities occurring within the haloclines and brines ... -
Genome-Based Metabolic Reconstruction Unravels the Key Role of B12 in Methionine Auxotrophy of an Ortho-Phenylphenol-Degrading Sphingomonas haloaromaticamans
(2020)Auxotrophy to amino acids and vitamins is a common feature in the bacterial world shaping microbial communities through cross-feeding relations. The amino acid auxotrophy of pollutant-degrading bacteria could hamper their ... -
Greenhouse biofumigation with Melia azedarach controls Meloidogyne spp. and enhances soil biological activity
(2018)The need for environmentally friendly agricultural practices has led to the development of plant-based nematicides for root-knot nematode control. The efficacy of these botanicals has been tested primarily under laboratory ... -
Impact of twenty pesticides on soil carbon microbial functions and community composition
(2022)Pesticides are known to affect non-targeted soil microorganisms. Still, studies comparing the effect of multiple pesticides on a wide range of microbial endpoints associated with carbon cycling are scarce. Here, we employed ... -
Multi-species relationships in legume roots: From pairwise legume-symbiont interactions to the plant - Microbiome - soil continuum
(2021)Mutualistic relationships of legume plants with, either bacteria (like rhizobia) or fungi (like arbuscular mycorrhizal fungi), have been investigated intensively, usually as bi-partite interactions. However, diverse symbiotic ... -
Novel insights into the metabolic pathway of iprodione by soil bacteria
(2017)Microbial degradation constitutes the key soil dissipation process for iprodione. We recently isolated a consortium, composed of an Arthrobacter sp. strain C1 and an Achromobacter sp. strain C2, that was able to convert ... -
Pesticide effects on nitrogen cycle related microbial functions and community composition
(2022)The extensive application of pesticides in agriculture raises concerns about their potential negative impact on soil microorganisms, being the key drivers of nutrient cycling. Most studies have investigated the effect of ... -
The potential of organic substrates based on mushroom substrate and straw to dissipate fungicides contained in effluents from the fruit-packaging industry - Is there a role for Pleurotus ostreatus?
(2016)Citrus fruit-packaging plants (FPP) produce large wastewater volumes with high loads of fungicides like ortho-phenylphenol (OPP) and imazalil (IMZ). No methods are in place for the treatment of those effluents and biobeds ... -
The response of soil and phyllosphere microbial communities to repeated application of the fungicide iprodione: Accelerated biodegradation or toxicity?
(2020)Pesticides interact with microorganisms in various ways with the outcome being negative or positive for the soil microbiota. Pesticides' effects on soil microorganisms have been studied extensively in soil but not in other ... -
Role of microbial diversity for sustainable pyrite oxidation control in acid and metalliferous drainage prevention
(2020)Acid and metalliferous drainage (AMD) remains a challenging issue for the mining sector. AMD management strategies have attempted to shift from treatment of acid leachates post-generation to more sustainable at-source ...
