On Modeling Complex Collective Behavior in Myxobacteria
This paper reviews recent progress in modeling collective behaviors in myxobacteria using lattice gas cellular automata approach (LGCA). Myxobacteria are social bacteria that swarm, glide on surfaces and feed cooperatively. When starved, tens of thousands of cells change their movement pattern from outward spreading to inward concentration; they form aggregates that become fruiting bodies. Cell...
متن کاملEffect of carbohydrates on some Myxobacteria.
The nutrition of the myxobacteria has received little attention. Beebe (1943) tested various myxobacteria including Myxococcus fulvus, Polyangium erectum, Myxococcus virescens, ChondroCOCCU8 blastic, and Myxococcus xanthus for their utilization of various carbohydrates. He found that these myxobacteria grew moderately well on unsupplemented 1.5 per cent agar without the addition of any other ca...
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 کاملHow 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 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...
