Extraction and Analysis of Extracellular Polymeric Substances: Comparison of Methods and Extracellular Polymeric Substance Levels in Salmonella pullorum SA 1685
Extracellular polymeric substances (EPS) production and composition for Salmonella pullorum SA 1685 exposed to artificial groundwater (AGW) has been examined utilizing three EPS extraction methods: lyophilization, ethanol, and sonication. Experiments were carried out to evaluate the robustness of three EPS extraction methods and the sensitivity of each to subtle changes in solution ionic streng...
متن کاملCharacterization and Molecular Identification of Extracellular Polymeric Substance (EPS) Producing Bacteria from Activated Sludge
The aim of this study was identification and characterization of highly efficient Extracellular Polymeric Substance (EPS) producing bacteria in activated sludge. Among 74 isolated bacteria, 20 EPS-producing bacteria were obtained from wastewater treatment plant of Bojnourd. EPS extraction was performed using absolute ethanol after glucose-enriched culture. Dry weight, concentration, and the rat...
متن کاملToxic substance from a natural bloom of Microcystis aeruginosa.
A toxic substance contained in the blue-green alga Microcystis aeruginosa was purified and partially characterized. Toxic algal cells were collected from a highly eutrophic lake in Japan, and the toxin was purified by homogenization, ultrafiltration, gel filtration, and ion-exchange chromatography. The final preparation gave a single peak on high-performance liquid chromatography. The toxicity ...
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...
متن کاملMechanism of adsorption of ferric iron by extracellular polymeric substances (EPS) from a bacterium Acidiphilium sp.
The aim of this study was to assess the sorption of Fe(III) by extracellular polymeric substances (EPS) of the Acidiphilium 3.2Sup(5) bacterium, which has promising properties for use in microbial fuel cells (MFC). The EPS of A. 3.2Sup(5) was extracted using EDTA. The sorption isotherms were determined using aliquots of purified EPS. The exosubstances loaded with metal were characterized by sca...
