Definition

noun

Typical halotolerant gram-negative spore forming aerobes that are elongated rod shape with no flagella and normally found in coastal seawater.

Supplement

Myxococcus fulvus has a developmental cycle that forms multicellular fruiting bodies which contains spores having genomes that are between 9 and 10 Mbp long bigger than severalfree-living bacteria.

Myxobacteria normally have a pH range from 5 to 8 and some can be found at extreme pH. It has been revealed thatfruiting body structures are possible and effective in inundated environment thus, it is a flexible genus due to its gliding ability. Some unusual behaviors of these bacteria exhibit suicide to guarantee the survival of other cells wherein through the course of fruiting body formation merely few cells will tend to aggregate instead it will lyses releasing contents that serves as feeding mechanisms of sporulating cells.

In culture medium it forms colonies on agar that spread over the whole plate after 72 hours and regularly displays concentric rings.

Life cycle of Myxococcus fulvus undergo different stages such as the germinating microcysts, juvenile vegetative cells,intermediate cells, mature cells and resting microcysts. Germination carried out bygerm-tube formation. The nucleus of the germinating microcyst is a single oval body while the young vegetative cells are multinucleate because the nucleus consists of a string oflobate bodies. In intermediate and mature cells the nucleus are bi-lobed with the appearance of the entire edges.
