Anaerobic bacteria from hypersaline environments.
Three genera and five species of halophilic methylotrophic methanogens have been reported, and a bloom of phototrophic bacteria in the marine salterns of Salins-de-Giraud, located on the Mediterranean French coast in the Rhone Delta, is also described. Expand
Microbial mats in the hypersaline ponds of Mediterranean salterns (Salins-de-Giraud, France)
It has been found that the accumulated sulfide is oxidized not only by the phototrophic bacteria in the sulfide oxidation zone but also by the oxygen produced by the cyanobacteria which are able to photosynthesize in the presence of sulfide. Expand
Characterization of functional bacterial groups in a hypersaline microbial mat community (Salins-de-Giraud, Camargue, France).
Analysis of characteristic biomarkers revealed that cyanobacteria were the major component of the pond, in addition to diatoms and other algae, and functional bacterial groups involved in the sulfur cycle could be correlated to these biomarkers. Expand
Impact of an Urban Effluent on Antibiotic Resistance of Riverine Enterobacteriaceae andAeromonas spp
The urban effluent resulted in an increase of the rates of resistance to antibiotics other than quinolones in the riverine bacterial populations, despite limited genetic exchanges between enterobacteria and Aeromonas. Expand
Eutrophication gradients in coastal lagoons as exemplified by the Bassin d'Arcachon and the Étang du Prévost
From the comparison of the selected sites, three stages of eutrophication are recognized according to the conceptual model of Nienhuis (1992) describing the relation between the relative dominance of primary producers connected to the availability of nutrients. Expand
Effects of Heavy Fuel Oil on the Bacterial Community Structure of a Pristine Microbial Mat
This study shows the major changes that occur in the microbial mat community at different time periods following contamination, and demonstrates the resilience of this microbial ecosystem in resisting environmental stress resulting from oil pollution. Expand
Antimicrobial resistance of mesophilic Aeromonas spp. isolated from two European rivers.
The activity of 19 antibiotics and four antiseptics and/or disinfectants was studied against 138 non-redundant strains of Aeromonas spp. (104 Aeromonas caviae, 22 Aeromonas sobria and 12 AeromonasExpand
Molecular sequence analysis of prokaryotic diversity in the anoxic sediments underlying cyanobacterial mats of two hypersaline ponds in Mediterranean salterns.
This study represents the first molecular analysis of the diversity of halophilic prokaryotes present in these sediments and the results are discussed in the light of the current knowledge of the microbial ecology of these hypersaline ecosystems. Expand
Occurrence of Listeria spp. in Effluents of French Urban Wastewater Treatment Plants
ABSTRACT Listeria spp. were found in most treated waters (84.4%) and raw sludge (89.2%) of six French urban wastewater treatment plants and one composting facility, examined monthly over a 1-yearExpand
Artificial Wetland Performances in the Purification Efficiency of Hydrocarbon Wastewater
An artificial wetland planted with Typha latifolia was fed during a 360-day experiment with a reconstituted hydrocarbon wastewater and observed a high development of aerobic heterotrophic bacteria and hydrocarbon-utilizing bacteria, which probably interacted with the plants for the biodegradation of hydrocarbon.
