Analysis of marine cyanobacteria and proteobacteria genomes has provided a profound understanding the life strategies these organisms their ecotype differentiation metabolisms. However, comparable analysis Bacteroidetes, third major bacterioplankton group, is still lacking. In present paper, we report on genome Polaribacter sp. strain MED152. On one hand, MED152 contains substantial number genes for attachment to surfaces or particles, gliding motility, polymer degradation. This agrees with...
The Mediterranean coast receives large inputs of dust with a potential fertilization effect. We evaluated the effect wet deposition event on microbial abundance and activity, community structure metabolic balance. Dust collected during storm was added to series microcosms. realistic concentration (0.05 g L−1) based phosphorus contained in and, addition, we included P amended tank distinguish from that dust. also higher (0.5 L−1). increased initial water–phosphorus by 0.3 µM dissolved organic...
Summary We used catalysed reported deposition – fluorescence in situ hybridization (CARD‐FISH) to analyse changes the abundance of bacterial groups Alphaproteobacteria , Gammaproteobacteria and Bacteroidetes, hydrocarbon‐degrading Cycloclasticus bacteria mesocosms that had received polycyclic aromatic hydrocarbons (PAHs) additions. The effects PAHs were assessed under four contrasting hydrographic conditions coastal upwelling system Rías Baixas: winter mixing, spring bloom, summer...
We used mesocosm experiments to study the bacterioplankton community in a highly dynamic coastal ecosystem during four contrasting periods of seasonal cycle: winter mixing, spring phytoplankton bloom, summer stratification and autumn upwelling. A correlation approach was order measure degree coupling between dynamics major bacterial groups, heterotrophic carbon cycling environmental factors. catalysed reporter deposition-fluorescence situ hybridization follow changes relative abundance most...
To decipher the response of mesopelagic prokaryotic communities to input nutrients, we tracked changes in abundance, extracellular enzymatic activities, heterotrophic production, dark dissolved inorganic carbon (DIC) fixation, community composition (16S rRNA sequencing) and gene expression (metatranscriptomics) 3 microcosm experiments with water from North Atlantic. Responses different treatments amended thiosulfate, ammonium or organic matter (i.e. pyruvate plus acetate) were compared...
Bacteria in the family Flavobacteriaceae are increasingly recognized to play important roles degradation of organic matter during and following algal blooms. A novel heterotrophic, rod-shaped, aerobic, yellow-pigmented gliding bacterium was isolated from a seawater sample collected Bay Blanes north-western Mediterranean Sea. Analysis its 16S rRNA gene sequence, retrieved whole-genome showed that closely related members genus Leeuwenhoekiella within Flavobacteriaceae, phylum Bacteroidetes....
Catalysed reported deposition-FISH and clone libraries indicated that Roseobacter, followed by Bacteroidetes, some gammaproteobacterial groups such as SAR86, dominated the composition of bacterioplankton in Ría de Vigo, NW Spain, detriment to SAR11 (almost absent this upwelling ecosystem). Since we sampled four times during year, observed pronounced changes structure each component, particularly for Roseobacter lineage. We suggest variations coastal ecosystem Vigo were associated with...

A Gram-negative, slightly halophilic, strictly aerobic, motile chemoorganotrophic bacterium, strain MED92 T , was isolated from a surface water sample the eastern Mediterranean Sea. Phylogenetic analysis based on its 16S rRNA gene sequence, retrieved whole-genome demonstrated that this isolate is unique, showing <93 % sequence similarity to species of families Oceanospirillaceae and Alteromonadaceae . The polar lipid profile novel consisted phosphatidylethanolamine, phosphatidylglycerol,...
Viruses are abundant, diverse and dynamic components of the marine environments play a significant role in ocean biogeochemical cycles. To assess potential variations relation between viruses microbes different geographic regions depths, viral microbial abundance production were determined throughout water column along latitudinal transect South Atlantic Ocean. Path analysis was used to examine relationships several abiotic biotic parameters populations distinguished by flow cytometry. The...
Background: Wastewater treatment plants (WWTPs) are microbial factories aimed to reduce the amount of nutrients and pathogenic microorganisms in treated wastewater before its discharge into environment. We studied impact urban WWTP effluents on abundance antibiotic resistance genes (ARGs) antibiotic-resistant Escherichia coli (AR-E. coli) last stretch two rivers (Arrone Tiber) Central Italy that differ size flow volume. Methods: Water samples were collected three seasons upstream downstream...
A novel heterotrophic, marine, strictly aerobic, motile bacterium was isolated from the Red Sea at a depth of 1 m. Analysis its 16S rRNA gene sequence, retrieved whole-genome showed that this most closely related to genera Oleispira, Oceanobacter and Thalassolituus, each which contains single species, within class Gammaproteobacteria. Phenotypic, genotypic phylogenetic analyses supported creation genus species accommodate bacterium, for name Bermanella marisrubri gen. nov., sp. nov. is...

We studied the importance of dissolved primary production in a coastal, productive ecosystem relation to phytoplankton biomass, community structure and productivity. The photosynthetic organic carbon (DOCp) particulate was determined mesocosm experiments during four contrasting oceanographic periods Ría de Vigo (NW Iberian Peninsula). also size-fractionated chlorophyll concentration production, taxonomic composition bacterial production. Phytoplankton biomass dominated by >20 µm size...
A novel heterotrophic, moderately halophilic, strictly aerobic, motile bacterium was isolated from a seawater sample collected at the Blanes Bay Microbial Observatory in north-western Mediterranean Sea. Analysis of its 16S rRNA gene sequence, retrieved whole-genome showed that this most closely related to single-species genera Reinekea and Saccharospirillum (95 94 % sequence similarity, respectively) within class Gammaproteobacteria .
