True chemotaxis in oxygen gradients of the sulfur-oxidizing bacterium Thiovulum majus

Appl Environ Microbiol. 2001 Jul;67(7):3299-303. doi: 10.1128/AEM.67.7.3299-3303.2001.

Abstract

Observations of free-swimming Thiovulum majus cells show that these bacteria exhibit a phobic response as well as true chemotaxis in oxygen gradients. Both phenomena of their chemotactic behavior are integrated into a single model of helical klinotaxis, which is demonstrated by computer simulations.
