Cr(VI) reduction by an extracellular polymeric substance (EPS) produced from a strain of Pseudochrobactrum saccharolyticum

Composition of Extracellular Polymeric Substances (EPS) produced by Flavobacterium columnare isolated from tropical fish in Brazil

Thirty nine isolates of Flavobacterium columnare from Brazilian fish farms had their carbohydrate composition of EPS evaluated by high efficiency liquid chromatography, using the phenol-sulfuric acid method of EPS. The occurrence of capsules on F. columnare cells was not directly related to biofilm formation, and the predominant monosaccharide is glucose.

Characterization 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...

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...

Mechanism 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...

Characteristics of a bacteriocin -like substance produced by Clostridium haemolyticum strain IRP - 135
