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, ... -
Apparent richness and community composition of Bacteria and Archaea in geothermal springs
(2009)The archaeal and bacterial 16S rRNA gene diversities of the Polihnitos (89 degrees C), Edipsos (81.8 degrees C), Thermopiles (38.9 degrees C), Eleftheres (41.2 degrees C) and Lagadas (35.2 degrees C) geothermal springs in ... -
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 ... -
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 ... -
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 ... -
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 ... -
Dietary differences are reflected on the gut prokaryotic community structure of wild and commercially reared sea bream (Sparus aurata)
(2014)We compared the gut prokaryotic communities in wild, organically-, and conventionally reared sea bream (Sparus aurata) individuals. Gut microbial communities were identified using tag pyrosequencing of the 16S rRNA genes. ... -
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 ... -
Factors Structuring the Epiphytic Archaeal and Fungal Communities in a Semi-arid Mediterranean Ecosystem
(2021)The phyllosphere microbiome exerts a strong effect on plants’ productivity, and its composition is determined by various factors. To date, most phyllosphere studies have focused on bacteria, while fungi and especially ... -
A freestanding proofreading domain is required for protein synthesis quality control in Archaea
(2004)Threonyl-tRNA synthetase (ThrRS) participates in protein synthesis quality control by selectively editing the misacylated species Ser-tRNAThr. In bacteria and eukaryotes the editing function of ThrRS resides in a highly ... -
Inter-comparison of the potentially active prokaryotic communities in the halocline sediments of Mediterranean deep-sea hypersaline basins
(2015)The sediment microbiota of the Mediterranean deep-sea anoxic hypersaline basins (DHABs) are understudied relative to communities in the brines and halocline waters. In this study, the active fraction of the prokaryotic ... -
Microbiological confinement of two adjacent water wells in Lake Karla Basin, Greece
(2015)We analyzed the bacterial and archaeal community structure of two adjacent irrigation well waters of the Lake Karla Basin, Central Greece, in order to elucidate their connectivity or confinement by using 454 tag pyrosequencing ... -
NAT/NCS2-hound: a webserver for the detection and evolutionary classification of prokaryotic and eukaryotic nucleobase-cation symporters of the NAT/NCS2 family
(2018)Nucleobase transporters are important for supplying the cell with purines and/or pyrimidines, for controlling the intracellular pool of nucleotides, and for obtaining exogenous nitrogen/carbon sources for metabolism. ... -
A non-phylogenetic alpha diversity approach on prokaryotic community structure in aquatic systems
(2013)Comparative analyses of accumulating phylotype-abundance data of prokaryotic communities are relatively scarce and mainly approached with phylogenetic methodologies. However, when a great fraction of phylotypes is captured ... -
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 ... -
Prokaryotic community structure and diversity in the sediments of an active submarine mud volcano (Kazan mud volcano, East Mediterranean Sea)
(2010)We investigated 16S rRNA gene diversity at a high sediment depth resolution (every 5 cm, top 30 cm) in an active site of the Kazan mud volcano, East Mediterranean Sea. A total of 242 archaeal and 374 bacterial clones were ... -
Prokaryotic diversity in biodeteriorated wood coming from the Bükkábrány fossil forest
(2016)The oldest standing paleo-forest in the world is located at Bükkábrány in Hungary. Some 7 million years ago a sudden and rapid deposition of sands from a prograding delta resulted in rise of the level of Lake Pannon that ... -
The response of soil and phyllosphere microbial communities to repeated application of the fungicide iprodione: Accelerated biodegradation or toxicity?
