Ammonia-induced inhibition of manure-based continuous biomethanation process under different organic loading rates and associated microbial community dynamics
(2021)Three Continuously Stirred Tank Reactors (CTSRs) were operating at steady state conditions with Organic Loading Rates (OLR) of 2.09, 3.024 and 4.0 g VS L−1 d−1. Glucose was used as the sole factor for increasing the OLR, ... -
Antimicrobial resistance of animal and human strains of enterobacteriaceae in Greece
(2003)Two hundred sixty two strains of Enterobacteriaceae from animal and human sources where intermixing and/or spreading is possible were examined for their resistance to 15 antimicrobials frequently used in animal prophylaxis ... -
Application of bioassays and soil column test for toxicity evaluation of selected pesticides
(2008)The toxic effects of an organophosphate nematicide (Fosthiazate) and a benzenoid fungicide (Metalaxyl-M) have been evaluated by the use of thefresh water algae P. subcapitata. The effects of copper (Cu+2), an ingredient ... -
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 ... -
Assessment of the impact of three pesticides on microbial dynamics and functions in a lab-to-field experimental approach
(2018)The toxicity of pesticides on soil microorganisms is as an emerging area of concern. Novel and well-standardized tools could be now used to provide a robust assessment of the ecotoxicity of pesticides on soil microorganisms. ... -
Asymmetric behavior of archaeal prolyl-tRNA synthetase
(2005)Archaeal prolyl-tRNA synthetases differ from their bacterial counterparts: they contain an additional domain (about 70 amino acids) appended to the carboxy-terminus and lack an editing domain inserted into the class II ... -
Atrazine, chlorpyrifos, and iprodione effect on the biodiversity of bacteria, actinomycetes, and fungi in a pilot biopurification system with a green cover
(2017)The use of biopurification systems can mitigate the effects of pesticide contamination on farms. The primary aim of this study was to evaluate the effect of pesticide dissipation on microbial communities in a pilot ... -
Bacterial and archaeal phylotypes associated with distinct mineralogical layers of a white smoker spire from a deep-sea hydrothermal vent site (9°N, East Pacific Rise)
(2006)A diffusely venting chimney spire from the East Pacific Rise (9°N) was analysed by petrographic thin sectioning and 16S rRNA gene cloning and sequencing in parallel, to correlate microbial community composition with ... -
The bacterial flora in the teat duct of ewes can protect against and can cause mastitis
(2007)We studied the possible effects of bacterial populations within the teat duct, in the pathogenesis of ovine mastitis. In experiment I, 32 ewes were allocated into group A (ewes from which we isolated (+++ growth) ... -
Bioaugmentation of animal feces as a mean to mitigate environmental contamination with anthelmintic benzimidazoles
(2021)Anthelmintics are used to control infestations of ruminants by gastrointestinal nematodes. The limited metabolism of anthelmintics in animals result in their excretion in feces. These could be piled up in the floor of ... -
Bioaugmentation of thiabendazole-contaminated soils from a wastewater disposal site: Factors driving the efficacy of this strategy and the diversity of the indigenous soil bacterial community
(2018)The application of the fungicide thiabendazole (TBZ) in fruit packaging plants (FPP) results in the production of effluents which are often disposed in adjacent field sites. These require remediation to prevent further ... -
Biochemical and genetic evidence for the presence of multiple phosphatidylinositol- and phosphatidylinositol 4,5-bisphosphate-specific phospholipases C in Tetrahymena
(2011)Eukaryotic phosphoinositide-specific phospholipases C (PI-PLC) specifically hydrolyze phosphatidylinositol 4,5-bisphosphate [PtdIns(4,5)P2], produce the Ca2+-mobilizing agent inositol 1,4,5-trisphosphate, and regulate ... -
Biotreatment and bacterial succession in an upflow immobilized cell bioreactor fed with fludioxonil wastewater
(2021)The large quantities and the persistent nature of fungicide wastewaters have increased the efforts towards a sustainable technological solution. In this context, fludioxonil-contaminated wastewater was treated in an upflow ... -
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 ... -
Case report: High prevalence rate of ovine mastitis, caused by coagulase-negative staphylococci and predisposed by increased gossypol consumption
(2004)A case of unusually high (>94%) prevalence of mastitis in a flock of dairy sheep, which was caused by coagulase-negative staphylococci (cnS) and associated with increased gossypol consumption, is presented. The animals ... -
Changes in heterotrophic Picoplankton community structure after induction of a phytoplankton bloom under different light regimes
(2019)Bacterial and archaeal diversity and succession were studied during a mesocosm experiment that investigated whether changing light regimes could affect the onset of phytoplankton blooms. For this, 454-pyrosequencing of the ... -
Characterization of the biodegradation, bioremediation and detoxification capacity of a bacterial consortium able to degrade the fungicide thiabendazole
(2017)Thiabendazole (TBZ) is a persistent fungicide used in the post-harvest treatment of fruits. Its application results in the production of contaminated effluents which should be treated before their environmental discharge. ... -
Dimerization of the AtoC response regulator and modelling of its binding to DNA
(2010)Bacterial signal transduction systems can be viewed as an entity of multi-sensory and output domains, whereas the functions of response regulators play a pivotal role in the complex network interactions. One crucial property ... -
Direct detection of Cardiobacterium hominis in serum from a patient with infective endocarditis by broad-range bacterial PCR
(2006)Bacterial DNA was detected directly to the serum of a patient with endocarditis by broad-range 16S rRNA PCR followed by sequencing and analysis of the results by the BLAST search. Using these methods, Cardiobacterium hominis ... -
