The Genus Leucothrix

  • Thomas D. Brock


Leucothrix, a large-diameter, morphologically distinct, marine gliding bacterium, has been known in natural material since the time of Oersted in 1844, but its modern history began with the remarkable study Harold and Stanier published in 1955. In the introduction to their paper, Harold and Stanier state: “Leucothrix may be characterized succinctly as a chemoheterotrophic counterpart of the colorless sulfur-oxidizing organism Thiothrix. It has been observed on a few occasions... in the century since its original description, but the existing accounts of its morphology and development, based entirely on the examination of crude cultures, are either incomplete or inaccurate. Thanks to the ease with which it can be grown in pure culture, we have been able to determine its complete cycle of development, which includes a unique and hitherto undescribed process of gonidial aggregation to form many-celled rosettes.”
