Myxobacterales An order of Gram-negative bacteria, which are capable of a gliding motility when in contact with a surface. Vegetative cells are rod-shaped, and often embedded in slime. Under suitable conditions cells aggregate to form a fruiting body containing resting cells; fruiting bodies are often brightly coloured and may be visible to the naked eye. These bacteria are aerobic chemoorganotrophs, obtaining nutrients mainly by producing enzymes that disrupt other bacteria or fungi. There are many species, found, for example, in soil, dung, and decaying plant matter.
