510 Conclusions We have shown evidence for the bridging flocculation of PSL by p-LG. The change in surface charge of the PSL spheres resulting from adsorption of p-LG molecules correlates with the formation of aggregates bridged by protein molecules. To develop models of the kinetics of bridging flocculation, some measurements of aggregation as a function of time and temperature have been carri...

1. Flocculation reactions of anti-erythrocyte sera on emulsions of alcoholic extract of blood are described. 2. The reactions are markedly species-specific. 3. Besides the homologous reactions certain others-"heterogenetic"" ones-have been observed, and in this way the existence of new examples of heterogenetic antibodies has been demonstrated. 4. Group-specific substances can be extracted from...

The authors present a novel ultra scale-down (USD) methodology for the characterization of flocculation processes. This USD method, consisting of a multiwell, magnetically agitated system that can be fitted on the deck of a liquid handling robot, mimicked the flocculation performance of a nongeometrically similar pilot-scale vessel representing greater than three orders of magnitude scale-up. M...

Extracting high-purity DNA directly from soil has become essential for the study of microorganisms in environmental samples. However, many soils contain compounds that inhibit enzymes involved in manipulating DNA. In this study, chemical flocculation using multivalent cations was investigated as a potential method for eliminating soil-based inhibitors during the extraction process. The addition...

Abstract Flocculation is used for the removal or separation of colloids, e.g. in water treatment and mineral processing. Alginates are linear, anionic biopolymers composed mannuronic (M) guluronic (G) acids. The relative amount distribution M G impact ion-binding gel-forming properties polymer, but still no one has yet addressed alginate composition on flocculation nanoparticles particles. Our ...

The development of clean and renewable biofuels has been wide concern on the topic energy environmental issues. As a kind biomass with great application prospects, microalgae have many advantages are used in fields protection as well food or feed production for humans animals. However, high cost harvesting is main bottleneck industrial large scale. Self-flocculation cost-efficient promising met...

In 1943 Bruger (1) proposed a fractional cephalin-cholesterol flocculation test to be used as an index of increasing or decreasing hepatic dysfunction. This modified test consisted in the use of increasing dilutions of serum with saline, noting the flocculation according to the procedure originally described by Hanger. The data presented in support of the modified test do show that, when it is ...

Background: The dispersed phase volume fraction plays key role in oil-in-water emulsion stability by different mechanisms like partial flocculation, depletion flocculation and bridging flocculation. Since the mentioned mechanism is affected by emulsifier concentration presented in system, the major aim of this study was to investigate the effect of dispersed phase volume fraction on physical st...
