This study investigated the physiology and behaviour following treatment with ortho-phthalaldehyde (OPA), of Pseudomonas fluorescens in both the planktonic and sessile states. Steady-state biofilms and planktonic cells were collected from a bioreactor and their extracellular polymeric substances (EPS) were extracted using a method that did not destroy the cells. Cell structure and physiology af...

Biological processes, such as activated sludge and granular sludge are widely used to remove organic pollutants as well as inorganic pollutants, such as metallic elements1–3, which are known to be potentially toxic, and impact the performance of biological waste treatment processes4. Granular sludge is a dense aggregate of microorganisms, minerals, and microbial produced compounds such as extra...

Effectof exopolysaccharides (EPS) produced by a consortium of cyanobacteria on germination of three crops wheat, maize and rice was studied at different salt concentrations. Production of EPS was found to be stimulated by salts, which in turn had a significant Na+ removal capability from aqueous solution. Seed germination, vigor index and mobilization efficiency in all the three crops remarkabl...

The influence of different carbon and nitrogen sources, of ethanol concentration, the optimal pH, temperature and medium composition were evaluated on extracellular polysaccharides (EPS) synthesis and bacterial growth of Gluconacetobacter hansenii LMG1524, and preliminary characterization of EPS was investigated. The highest EPS yields were obtained using glycerol and ammonium sulphate as carbo...

Elastin peptides (EPs) generated by hydrolysis of elastic fibers by elastinolytic enzymes display a wide spectrum of biological activities. Here, we investigated their influence on rat heart ischemia-mediated injury using the Langendorff ex vivo model. EPs, i.e., kappa elastin, at 1.32- and 660-nM concentrations, when administered before the ischemia period, elicited a beneficial influence agai...

BACKGROUND This study evaluated the measurement properties of a newly developed instrument - the Self-Management Profile for Type 2 Diabetes (SMP-T2D). METHODS The 18-item SMP-T2D assesses 12 constructs: level and perceived ease of performance in five self-care domains (blood glucose monitoring, medication-taking, healthy eating, being physically active, and coping), and two global constructs...

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...

Trichomonas vaginalis infection is one of the most prevalent sexually transmitted infections in humans and is now recognized as an important cause of infertility in men. There is little information about the effect of extracellular polymeric substances (EPS) from T. vaginalis on sperm, but previous reports do not provide a conclusive description of the functional integrity of the sperm. To inve...
