Ward L. Johnson, Danielle C. France, F L. Walls, William T. Cordell, Nikki S. Rentz
An approach is presented for sensing mechanical fluctuations of bacteria, with potential application in monitoring microbial responses to changes in chemical environment, such as antimicrobial intervention. Bacteria are tethered to a quartz crystal

Direct measurement of Vorticella contraction force by micropipette deflection

February 17, 2017
Author(s)
Danielle C. France, Jonathan Tejada, Paul Matsudaira
The ciliated protozoan Vorticella convallaria is noted for its exceptionally fast ATP-independent cellular contraction, but direct measurements of contractile force have proven difficult given the length scale, speed, and forces involved. We used high

Anti-corrosive influence of Acetobacter biofilms on carbon steel

July 19, 2016
Author(s)
Danielle C. France
Microbiologically influenced corrosion (MIC) of carbon steel infrastructure is an emerging cost issue for the ethanol fuel industry. One bacterial species found in ethanol fuel environments, Acetobacter aceti, can convert ethanol to the corrosive species
