Motile Behavior of Bacteria
© 2000 American Institute of Physics, S-0031-9228-0001-010-3 E coli is a singlecelled organism that lives in your gut. It is equipped with a set of rotary motors only 45 nm in diameter. Each motor drives a long, thin, helical filament that extends several cell body lengths out into the external medium. The assemblage of motor and filament is called a flagellum. The concerted motion of several f...
متن کاملElectrophoresis of motile bacteria.
For over 30 years the technique of microelectrophoresis has been used to study the surface properties of bacteria and other particles of microscopic size. Since flagella undoubtedly act as cellular surface components, they would be expected to contribute to the electrophoretic behavior of the cells. Likewise, vital motion might be expected to complicate electrophoretic measurements of flagellat...
متن کاملLight Scattering from Motile Bacteria
The (( Intermediate scattering function )t I(K, t ) of light scattered by motile bacteria is shown to be I(K, t ) = rn sin KVt jo T v T Ps(V) dV, (1) where Ps(V) is the distribution of swimming speeds of the bacteria. ~cattercd spectra from motile E, Coli Klz bacteria have been investigated by laser light intensity correlation spectroscopy. [Z(K, t ) ] z is obtained from the data and its angula...
متن کاملEnhanced diffusion due to motile bacteria
The effect of bacterial motion on the diffusion of a molecule of high molecular weight is studied by observing the mixing of two streams of fluid in a microfluidic flow cell. We show that the presence of motile E. coli bacteria in one of the streams results in a marked increase in the effective diffusion coefficient of Dextran, which rises linearly with the concentration of bacteria from a base...
متن کاملDeployable micro-traps to sequester motile bacteria
The development of strategies to reduce the load of unwanted bacteria is a fundamental challenge in industrial processing, environmental sciences and medical applications. Here, we report a new method to sequester motile bacteria from a liquid, based on passive, deployable micro-traps that confine bacteria using micro-funnels that open into trapping chambers. Even in low concentrations, micro-t...
