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 ...

The processing of harvested E. coli cell broths is examined where the expressed protein product has been released into the extracellular space. Pre-treatment methods such as freeze-thaw, flocculation, and homogenization are studied. The resultant suspensions are characterized in terms of the particle size distribution, sensitivity to shear stress, rheology and solids volume fraction, and, using...

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...

In the phosphate industry, thickening process is vital to increasing solid slurry concentration and recovering water that as clear possible. The performance of depends mainly on coagulation–flocculation effect. based flocculant agents concentrate particles: flotation washing plant rejects large flocs, which accelerate their sedimentation velocity. industry worldwide uses synthetical flocculants...

FLO11 encodes a yeast cell wall flocculin that mediates a variety of adhesive phenotypes in Saccharomyces cerevisiae. Flo11p is implicated in many developmental processes, including flocculation, formation of pseudohyphae, agar invasion, and formation of microbial mats and biofilms. However, Flo11p mediates different processes in different yeast strains. To investigate the mechanisms by which F...

A bioflocculant-producing bacteria, isolated from sediment samples of a marine environment in the Eastern Cape Province of South Africa demonstrated a flocculating activity above 60% for kaolin clay suspension. Analysis of the 16S ribosomal deoxyribonucleic acid (rDNA) nucleotide sequence of the isolate in the GenBank database showed 99% similarity to Bacillus toyonensis strain BCT-7112 and it ...
