Wavelike contractions of the outer membranes help the bacteria propel themselves. Members of the group include species of Cytophaga and Simonsiella . Two important genera of gliding bacteria are Beggiatoa and Thiothrix . Species of these organisms live in sulfur environments and break down hydrogen sulfide to release sulfur in the form of sulfur granules. For this reason, the bacteria are very important in the recycling of sulfur in water and soil. The bacteria are Gram-negative. Myxobacteria are gliding bacteria that are Gram-negative, aerobic rods. They are nonphotosynthetic species and have a unique developmental cycle that involves the formation of fruiting bodies. When nutrients are exhausted, the bacteria congregate and produce a stalk, at the top of which is a mass...
