Complex Investigations of Double Layer of Colloid Particles. Electric Conductivity of Suspensions and Anisotropy of Electrophoresis
Conditions for obtaining quantitative .ililformation on the double
layer of colloid particles on the basis of electrosurface measurements
have been analyzed. A rigorous theory of electric conductivdty
of diluted suspensions on the basis of induced dilpole
moments of particles has been presented.
The .isoconductance point of a suspension has been shown to
codncide wd.th the isopolarisation state of a particle. A theory of
anisotropy of the electrophoresis of long rod-like particles has been
put forward. The identity of the formules of electrophoresis of a
sphere and of cylindrical particles oriented pevpendicular towards
the field at a small thickness of the double layer has been shown.
A good agreement has been found between the values of induced
dipole moments and, specific surface conductivity in a wide electrolite
concentration range measured by the methods of electric
conductivity of suspensions and anisotropy of electrophoresis. The
theories of induced dipole moment, electric conductivity of suspension
and anisotropy of electrophoresis have been experimentally
examined

Procrustes imaging of unweighted UniFrac distance matrices highlight the diversity amongst the 16S bacterial component (A) and fungal component (B) of the different kefir samples.
<p>The two different sample types are linked with a bar (white represents grain flora; red represents milk flora). The direction of each axis is arbitrary.</p
Principle Coordinate Analysis (PCoA) plots, based on unweighted UniFrac distance matrices, show the diversity within bacterial populations from kefir grains (A) and kefir fermented milk (B) and fungal grain (C) and milk (D) populations.

Minimum inhibitory concentrations of purified nisin (WT) and nisin K12A against various Gram-positive targets.
<p>Results from minimum inhibitory concentration assays of purified nisin (WT) and nisin K12A against various Gram-positive targets. Values given are identical results from three independent determinations. Fold Difference represents the improvement of K12A compared to nisin against the relevant indicator.</p
Oligonucleotides used in this study.
<p>PHO indicates 5′ phosphate modification. Underlined sequences represent degenerate codon (N = A+C+G+T, K = G+T, M = A+C). Lower-case letters indicate site-directed mutation.</p
