Myxobacteria colonies during their aggregation phase propagate complex waves over their surface. These waves are fundamentally different from the analogous phenomenon in diffusion-reaction systems or in populations of Dictyostelium discoideum where colliding waves annhilate. Myxobacterial waves appear to pass through one another, analogous to solitons.

Sociobiology of the Myxobacteria
Annual Review of Microbiology, 2009Cooperation is integral to much of biological life but can be threatened by selfish evolutionary strategies. Diverse cooperative traits have evolved among microbes, but particularly sophisticated forms of sociality have arisen in the myxobacteria, including group motility and multicellular fruiting body development.

Annual Review of Microbiology, 2004
▪ Abstract Myxobacteria use soluble and cell-contact signals during their starvation-induced formation of fruiting bodies. These signals coordinate developmental gene expression with the cell movements that build fruiting bodies. Early in development, the quorum-sensing A-signal in Myxococcus xanthus helps to assess starvation and induce the first ...

Bacteriolytic Myxobacteria: Parasites or Scavengers?
Zentralblatt für Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene. Zweite Naturwissenschaftliche Abteilung: Allgemeine, Landwirtschaftliche und Technische Mikrobiologie, 1977The activity range of an enzymatic preparation from Myxococcus xanthus was assayed against some soil and rhizospheric bacteria. The lysis of unequally aged sensitive eubacterial populations, as related to their viability, was investigated and, at last, the often used streak method was checked and the relationship between cell viability and ...

1984
Colors in nature arise either through absorption by certain molecules or atoms of selected wavelengths in the visible range, or through interference of light waves in material with a special physical structure. Structural colors are observed with some cytophagas: Their delicate swarm colonies may act like a thin film and show iridescence (Reichenbach ...

Synthesis of myxobacteria metabolites
Pure and Applied Chemistry, 2012Myxobacteria are an excellent source of novel secondary metabolites with a range of biological activities. This review details the synthesis of several examples of these natural products. The total synthesis of all the members of the crocacin family is presented where the stereochemistry of the stereotetrad was set via a tin-mediated syn-aldol reaction

Control of Morphogenesis in Myxobacteria
CRC Critical Reviews in Microbiology, 1987The myxobacteria are Gram-negative soil bacteria that live in large communities known as swarms. The most remarkable characteristic of myxobacteria is their ability to form fruiting bodies that have a species-specific shape and color. Fruiting body formation requires the concerted effort of hundreds of thousands of cells.

Biologically active secondary metabolites from myxobacteria
Biotechnology Advances, 1993New chemical structures with proven biological activity still are badly needed for a host of applications and are intensively screened for. Suitable compounds may be used as such, or in the form of their derivatives or, equally important, may serve as lead compounds for designing synthetic analogs.

Development of the myxobacteria
1965The myxobacteria possess singular characteristics of vegetative growth, cellular morphology, and communal fructification which set them apart as a unique and distinctive order, the Myxobacteriales, within the class Schizomycetes.

CELLULOSE DECOMPOSING MYXOBACTERIA
2023200 strains belonging to the order Myxobacterales were isolated from farm yard manure, compost, liquid manure and soil. These strains were tested for their ability to utilize cellulose. Most of the strains decomposed the cellulose. Myxobacteria decomposed 9-82 per cent of cellulose. They are mesophilic aerobic microorganisms.
