Structure of exocellular polymers and their relationship to bacterial flocculation.
Several gram-negative, polarly flagellated rods were isolated on the basis of their flocculent growth habit. Some of the isolates possessed a capsular matrix which is composed of exocellular fibrils. Other isolates did not appear to have a capsular matrix when examined with a bright-field microscope with or without the aid of stains. However, these latter type isolates did possess exocellular m...
متن کاملRelaxation Times of Nano-Colloid Flocculation Induced by Adsorbing and Non-adsorbing Polymers
We have developed a self-consistent field theory of the effective interactions between nano-colloids mediated by adsorbing and non-adsorbing polymers. By making use of this theory, we have calculated the colloid immersion energy and the potential of the polymer-mediated forces for the above cases of polymer adsorption. On the basis of the obtained results for the polymer-mediated potentials, we...
متن کاملA simple bridging flocculation assay for rapid, sensitive and stringent detection of gene specific DNA methylation
The challenge of bringing DNA methylation biomarkers into clinic is the lack of simple methodologies as most current assays have been developed for research purposes. To address the limitations of current methods, we describe herein a novel methyl-protein domain (MBD) enrichment protocol for simple yet rapid and highly stringent selection of highly methylated DNA from limiting input samples. We...
متن کاملProtein adsorption induced bridging flocculation: the dominant entropic pathway for nano-bio complexation.
Lysozyme-silica interactions and the resulting complexation were investigated through adsorption isotherms, dynamic and electrophoretic light scattering, circular dichroism (CD), and isothermal titration calorimetry (ITC). A thermodynamic analysis of ITC data revealed the existence of two binding modes during protein-nanoparticle complexation. Both binding modes are driven by the cooperation of...
متن کاملPreparation Zirconia Toughened Alumina by Deflocculation-Flocculation Route (TECHNICAL NOTE).
Partially stabilized zirconia (PSZ) agglomerate toughened alumina has been prepared by the "deflocculation-flocculation" technique, using 2 and 3 mol. % Y2O3-doped zirconia powders. Samples containing up to about 30 vol.% zirconia were obtained. The resulting microstructure seems to be mainly influenced by the physical properties of the starting powders, e.g. agglomerate size and the specific s...
