The relationships between glucose metabolism and exopolysaccharide (EPS) production in a Lactococcus lactis strain containing the EPS gene cluster (Eps(+)) and in nonproducer strain MG5267 (Eps(-)) were characterized. The concentrations of relevant phosphorylated intermediates in EPS and cell wall biosynthetic pathways or glycolysis were determined by (31)P nuclear magnetic resonance. The conce...

Background: Bacterial Extracellular Polymeric Substances (EPS) are environmental friendly and versatile polymeric materials that are used in a wide range of industries such as: food, textile, cosmetics, and pharmaceuticals. To make the production process of the EPS cost-effective, improvements in the production yield is required which could be implemented through application of processes such a...

BACKGROUND Encapsulating peritoneal sclerosis (EPS) commonly presents after peritoneal dialysis has been stopped, either post-transplantation (PT-EPS) or after switching to hemodialysis (classical EPS, cEPS). The aim of the present study was to investigate whether PT-EPS and cEPS differ in morphology and clinical course. METHODS In this European multicenter study we included fifty-six EPS pat...

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...

Differential scanning calorimetry (DSC), thermogravimetry (TG) and Fourier-transform infra-red spectroscopy (FT-IR) analyses were performed to investigate changes in the physico-chemical properties of botryosphaerans, a family of exopolysaccharides (EPS) produced by the fungus Botryosphaeria rhodina MAMB-05 grown on glucose (EPS(GLC)), sucrose (EPS(SUC)) and fructose (EPS(FRU)). A slight endoth...

Yeast exopolysaccharide (EPS) are composed of unique sugar units, which offers an interesting perspective with respect to various food applications. This study aimed to characterize the EPS from Rhodotorula minuta BIOTECH 2178. Toxicological assessment of the EPS was investigated to ensure that it is safe for human consumption. The yeast EPS revealed high total sugar composition (59.2162-47%) a...

One of the main arguments against prescribing first generation ‘typical’ antipsychotics is that extrapyramidal symptoms (EPS) can emerge as a side effect. EPS are distressing and interfere with the recovery and functioning of patients. Some of these symptoms persist over long periods of time, even after antipsychotic usage has been stopped. It is believed that second generation antipsychotics a...

Pyruvic acid and O-acetyl groups are the major noncarbohydrate substituents in exopolysaccharides (EPS) produced by fast-growing species of Rhizobium. EPS substituent variations were observed among strains of the same species. The amounts of these substituents also varied with culture age; pyruvic acid increased in the EPS of all four species, whereas O-acetyl increased in Rhizobium trifolii an...

We explore statistical characteristics of avalanches associated with the dynamics of a complexnetwork model, where two modules corresponding to sensorial and symbolic memories interact, representing unconscious and conscious mental processes. The model illustrates Freud’s ideas regarding the neuroses and that consciousness is related with symbolic and linguistic memory activity in the brain. It...
