Redox properties of extracellular polymeric substances (EPS) from electroactive bacteria
Although the capacity for electroactive bacteria to convert environmental metallic minerals and organic pollutants is well known, the role of the redox properties of microbial extracellular polymeric substances (EPS) in this process is poorly understood. In this work, the redox properties of EPS from two widely present electroactive bacterial strains (Shewanella oneidensis and Pseudomonas putid...
متن کاملSeasonal dynamics of extracellular polymeric substances (EPS) in surface sediments of a diatom-dominated intertidal mudflat (Marennes-Oléron, France)
13 Numerous field-based investigations have highlighted that the production of Extracellular 14 Polymeric Substances (EPS) is physico-chemically and ecologically essential for intertidal 15 mudflats. EPS are largely secreted by marine benthic diatoms and their quantity and quality 16 are environmental-dependant. This paper focused on the dynamic pathways, concentration 17 rates and monosacchari...
متن کاملBiosorption of Cadmium by Non-Toxic Extracellular Polymeric Substances (EPS) Synthesized by Bacteria from Marine Intertidal Biofilms
Cadmium is a major heavy metal found in polluted aquatic environments, mainly derived from industrial production processes. We evaluated the biosorption of solubilized Cd2+ using the extracellular polymeric substances (EPS) produced by Bacillus sp. MC3B-22 and Microbacterium sp. MC3B-10 (Microbactan); these bacteria were originally isolated from intertidal biofilms off the coast of Campeche, Me...
متن کاملModulation of the Extracellular Polymeric Substances (EPS) Production by Quorum Sensing (QS) in Bacteria
Microorganisms are ubiquitous in their presence on the planet but the communication network they use to adapt, grow and survive is still under the exploration among the biologist world. The prokaryotic and eukaryotic microorganisms grow as single species or in consortium under diverse ecosystems synthesize and release macromolecules known as extracellular polymeric substances (EPS). These 80% e...
متن کاملSorption of ferrous and ferric iron by extracellular polymeric substances (EPS) from acidophilic bacteria.
The sorption of Fe(II) and Fe(III) by extracellular polymeric substances (EPS) of acidophilic bacteria Acidiphilium 3.2Sup(5) and Acidithiobacillus ferrooxidans, harvested from the ecosystem of the Tinto River (Huelva, Spain), was investigated. EPS from mixed cultures of both bacteria (EPS(mixed)) and pure cultures of A. 3.2Sup(5) (EPS(pure)) were extracted with ethylenediamine tetraacetic acid...
