Gliding Bacteria

	Tabular Form of Bacterial Classification From David Bergey's Manual This group (myxobacteria) consists of the Gram negative gliding bacteria characterized by unicellular rods greater than 1.5 µm in diameter covered by a slime. Multiplication is by binary transverse fission. Movement is by gliding in contact with a solid surface or air water interphase. The vegetative colony of myxobacters is called a , swarm or pseudoplasmodium because of the slime and gliding movement of the cells.
The pseudoplasmodium is usually flat and thin with many concentric folds and sometimes spreads rapidly as a result of outward movement of cells at the periphery. Differentiation occurs on specialized media. Further classification of this part is based on the characteristics of the fruiting bodies Cells within the fruiting bodies are dormant (myxospores). In some, myxospores cannot be readily distinguished from the vegetative cells as in Polyangiaceae while in others they are optically dense or refractile and encapulated (microcysts). All members are chemoorganotrophs and strictly aerobic.
Some species are cellulolytic (Cytophaga). Many are capable of lysing ether eucaryotic or procaryotic organisms (Myxococcus). They are non photosynthetic but may contain carotenoids, % G + C content varies from 67-71 moles. Mostly found in soil and decaying plant materials while few are aquatic. These are usually coloured and contain carotenoids pigments.
This part contains one order Myxobacteriales which is divided into two physiological groups. The bacteriolytic group including Myxococcaceae, Archangiaceae, Cystobacteraceae and Polyangiaceae, members of which are commonly found in animal dung, and which live on dead bacterial or yeast cells and the cellulolytic group, which can grow in a medium containing cellulose or simple sugars such as glucose and inorganic salts
