Bacterial world has seen to consist three major classes i.e. Eubacteria, Spirochaetae and Myxobacteria. Myxobacterium is one of the remarkable bacteria that has special distinctive property of multicellular and macroscopic features that are called fruiting bodies. Unlike other motile prokaryotes, myxobacterium does not have visible organelles of locomotion however, some of them show gliding motility. This signifies the complex life cycles of myxobacterium that come along with the diverse physiological characteristics.
FRUITING MYXOBACTERIA
MORPHOLOGY
//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Generally have long, slender and rod-shaped vegetative cells
Onset of nutrient depletion, vegetative cells aggregate and form spherical macrostructure of fruiting body
Due to its gliding motility, colony usually develops as a thin and spreading swarms
fruiting body usually raised above the surface and have a distinct pigmentation
Vegetative cell
Fruiting body
The genus Myxococcus are oftenly related to the unusual cell wall structure. Peptidoglycan were found at some part of the wall and held together by lipoprotein structure (Dworkin, 2007).
These combinations explain the flexibility for this type of myxobacteria
The extracellular matrix of M. xanthus consist of long and thin fibrils which emits from the cell surface
Vegetative cells appears to secrete polysaccharides slime which contains amino sugars
Colony appearance on the agar depends on the type of species and the medium used.
