How Myxobacteria Glide
BACKGROUND Many microorganisms, including myxobacteria, cyanobacteria, and flexibacteria, move by gliding. Although gliding always describes a slow surface-associated translocation in the direction of the cell's long axis, it can result from two very different propulsion mechanisms: social (S) motility and adventurous (A) motility. The force for S motility is generated by retraction of type 4 p...
متن کاملHow animals glide: from trajectory to morphology
Animals that glide produce aerodynamic forces that enable transit through the air in both arboreal and aquatic environments. The relative ease of gliding compared to flapping flight has led to a large diversity of taxa that have evolved some degree of flight capability. Glide paths are curved, reflecting the changing forces on the animal as it progresses through its aerial trajectory. These cha...
متن کاملLingering Puzzles about Myxobacteria
T he myxobacteria are social and capable of constructing intricate macroscopic structures called fruiting bodies. First recognized as bacteria in 1892 by the cryptogamic botanist Roland Thaxter, these exotic anomalies have proved challenging to microbiologists. Even so, we now know a great deal about the nutrition, life cycle, growth physiology, intermediary metabolism, structural chemistry, ge...
متن کاملBiomineralization induced by Myxobacteria
Myxococcus xanthus is a Gram negative, non-pathogenic, common soil bacterium that belongs to the δsubdivision of the Proteobacteria. According to the data, it is demonstrated that, depending on the chemistry of the culture media, M. xanthus is able to induce the formation of phosphates (struvite, schertelite, newberyite), carbonates (calcite, Mg-calcite, vaterite) and sulfates (barite, taylorit...
متن کاملAre Myxobacteria intelligent?
"Intelligence" is understood in different ways. Because humans are proud of their ability to speak, intelligence often includes the ability to communicate with others, to plan for the future, and to solve frequently encountered problems. Myxobacteria are among the most socially adept and ubiquitous of bacteria that live in the soil. To survive in nature, Myxobacteria communicate with their peer...
