Description and significance
Stigmatella aurantiac is a member of myxovbacteria, which are known to have complex development and differtiating life cycles, including one as individual organism and one in a group. Myxovbacteria also have a unique ability to aggregate and move as a population has the food source becomes scarce. Single cells can be motile by “adventurous motility” and seeks other Stigmatella aurantiac . As cell density increases, the organism switches to “social motility” of cells can gather together into masses termed fruiting bodies that may consist of up to 100,000 cells. There is a physical and metabolic change when Stigmatella aurantiac form fruiting bodies. Through chemical signals between cells, the Stigmatella aurantiac develop fruiting bodies almost as a multi-cellular organism, including specialized cells and differentiation of cellular structure according to position.
Stigmatella aurantiac is a rod shaped gram negative bacterium. They are terrestrial organisms that are commonly found on rotting wood and bark. As a mesophile, they grow in moderate temperatures (between 25-40 degrees Celsius). Their ability to move as a fruiting body was a well researched topic, and led to a deeper understanding of cell to cell communication and signals. Stigmatella aurantiac also produce anti microbial compounds, such as aurafuron A and stigmatellin, which may beimportant as anti cancer agents and to produce new antibodies.
