Sentence examples for mobility of bacteria from inspiring English sources
The electrophoretic mobility of bacteria cells suspended in PPB was measured using a laser Zeta Compact zetameter (CAD Instruments, Les Essarts-le-Roi, France), by tracking bacteria with a coupled device camera, under an electric field of 80 V.
A study published last week builds on evidence of the mobility of bacteria, antibiotics and those swappable bits of DNA that code for antibiotic resistance.
Addition of gentamicin at about 5 µg/ml (10.7 µM) immediately reduced the mobility of bacteria in the flow cell and increased their average oscillation period.
The antibiotics at this concentration pose no lethal effect but can cause differentiation of the bacteria's surface and induce modifications of cellular functions like adhesion, hydrophobicity of the surface, and mobility of bacteria and also interfere with the interactions between host and bacteria, such as phagocytosis or reactive oxygen species production by the phagocytes [ 10, 13].
The electrophoretic mobilities of bacteria which present LPS O1-Ag as the outermost layer (ie. B5055nm) were significantly lower than the mobilities of bacteria devoid of O-Ag (ie. B5055nmwaaF).
This observation suggests that the mobility of the bacteria in this assay was mostly determined by steric interactions caused by cell division.
These results indicate that the nature of the bacterial surface ultrastructure impacts significantly on the magnitude of the mobility of the bacterium, a phenomenon that is dependent on the ionic environment.
In general, the mobilities of the bacteria decreased (in absolute value) when the ionic strength of the buffer increased.
It is likely that in deep periodontal pockets of teeth with increased mobility the bacteria of "red complex," including Porphyromonas gingivalis, were present.
Image analysis software allowed recorded images to be processed in real time to calculate the electrophoretic mobilities from the displacement of bacteria subjected to a constant direct-current electric field (800 V/m).
The simulation results illustrate that contaminant transport is enhanced markedly in the presence of DOM and bacteria, and the impact of DOM on contaminant mobility is greater than that of bacteria under examined conditions.
