The effect of xanthan gum (XG) addition on physicochemical properties of 2wt% whey protein isolate (WPI) stabilized oil-in-water (O/W) emulsions containing 20% v/v menhaden oil was investigated by measuring droplet size, viscosity, microstructure, creaming profile and oxidative stability. In fresh emulsions, addition of XG at different concentrations did not show any significant effect on the s...

The flocculation performance of three poly(acrylic acid) (PAA) samples (Mw = 9 10, 2.5 10 and 1 10 g/mol) has been investigated. Colloidal alumina particles were used as a model system and tests were performed at pH 5. Using a singlecomponent polyacid, it was found that the optimum dosage required to achieve supernatant clarity was similar between the 9 10 g/mol PAA (23 ppm) and 2.5 10 g/mol PA...

A radiological study o f the small intestine o f 17 untreated patients in the acute phase ofschistosomiasis was performed. Twelve patients (70% o f total) had alterations: nine had clear-cut thickening o f the duodenal and jejunal folds, one flocculation, one fragmentation and one thickening o f mucosae, flocculation and fragmentation o f the barium column. There was no correlation o f the gast...

Analysis of a shear supernatant from flocculent, "fimbriated" Saccharomyces cerevisiae brewer's yeast cells revealed the presence of a protein involved in flocculation of the yeast cells and therefore designated a flocculin. The molecular mass of the flocculin was estimated to be over 300 kDa, as judged from sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Gel permeation chromatograph...

Coagulation and flocculation treatment processes play a central role in the way wastewater effluents are managed. Their primary function is particle removal that can impart colour to a water source, create turbidity, and/or retain bacterial and viral organisms. This study was carried out to investigate whether carbon nanotubes (CNTs) can be used as heterogeneous coagulants and/or flocculants in...

The use of flocculating yeast strains has been considered as a convenient approach to obtain high cell densities in bioreactors with increasing productivity in continuous operations. In Kluyveromyces marxianus ATTC 10022, the GAP1 gene encodes an isoform of glyceraldehyde-3-phosphate dehydrogenase-p37-that is accumulated in the cell wall and is involved in flocculation. To test the use of p37 a...
