“…4). We found this result unusual since no myxobacteria are known to grow at the salt concentrations found in seawater (41), even though several species of myxobacteria have been isolated from seashore sediments (2,43). The principal habitats for myxobacteria are associated with soil and are ubiquitously distributed worldwide.…”

The phylogenetic diversity of small-subunit rRNA genes associated with the domain Bacteria was examined (by using previously defined operational taxonomic units [C. L. Moyer, F. C. Dobbs, and D. M. Karl, Appl. Environ. Microbiol. 60:871-879, 1994]; those for Pele's Vents Bacteria are hereafter abbreviated PVB OTUs) with samples from a microbial mat at an active, deep-sea hydrothermal vent system. A cluster of phylogenetically related PVB OTUs (OTUs 2, 3, 6, and 8) was closely affiliated with Thiovulum sp. contained within the subclass of the class Proteobacteria and accounted for 60.5% of the small-subunit rRNA bacterial clone library from Pele's Vents. A second, smaller cluster of PVB OTUs (OTUs 1 and 11) was closely affiliated with Xanthomonas sp., contained within the ␥ subclass of the Proteobacteria and accounted for a total of 27.1% of the bacterial clone library. The remaining five PVB OTUs each accounted for 2.1% of the clones recovered and were affiliated with the following phylogenetic groups: PVB OTU 5 was a member of the Alteromonas group; PVB OTU 12 was a member of the Colwellia assemblage; PVB OTU 4 was loosely determined to be a member of the Thiothrix group, with the endosymbiotic bacteria from Bathymodiolus thermophilus and Calyptogena magnifica as the nearest relatives; PVB OTU 10B was a member of the Myxobacterium group; and PVB OTU 9A was a member of the Paraphyletic assemblage, with the Octopus Spring microbial mat type K clone as the closest known relative. PVB OTU 7 was determined to be a PCR-generated chimeric structure combined from two described phylotypes detected in this study, thereby decreasing the previously estimated number of major PVB OTUs from 12 to 11.

“…It was assumed for a long time that myxobacteria exclusively live in terrestrial habitats. Indeed, even in 1963, Brockman observed fruiting myxobacteria in sand samples from an ocean beach in South Carolina [ 97 ]. Species of the already known terrestrial genera Archangium , Chondrococcus ( Corallococcus ), Chondromyces , Myxococcus , and Polyangium , could be cultivated.…”

The discovery of new antibiotics is mandatory with regard to the increasing number of resistant pathogens. One approach is the search for new antibiotic producers in nature. Among actinomycetes, Bacillus species, and fungi, myxobacteria have been a rich source for bioactive secondary metabolites for decades. To date, about 600 substances could be described, many of them with antibacterial, antifungal, or cytostatic activity. But, recent cultivation-independent studies on marine, terrestrial, or uncommon habitats unequivocally demonstrate that the number of uncultured myxobacteria is much higher than would be expected from the number of cultivated strains. Although several highly promising myxobacterial taxa have been identified recently, this so-called Great Plate Count Anomaly must be overcome to get broader access to new secondary metabolite producers. In the last years it turned out that especially new species, genera, and families of myxobacteria are promising sources for new bioactive metabolites. Therefore, the cultivation of the hitherto uncultivable ones is our biggest challenge.

This review presents an overview of the present status of the biology of the myxobacteria, including the molecular biology of the systems that control and regulate myxobacterial gliding movement and morphogenesis. The present status of myxobacterial taxonomy and phylogeny is described. The evolutionary biology of the myxobacteria is emphasized with respect to their social behavior and the molecular basis of their signal chains. Most important within the metabolic physiology are the biologically active secondary metabolites of myxobacteria and their molecular mechanisms of action. The global distribution of myxobacteria in soils is described on the basis of data given in the literature as well as of comprehensive analyses of 1398 soil samples from 64 countries of all continents. The results are analyzed with respect to the spectrum and number of species depending on ecological and habitat-specific factors. The myxobacterial floras of different climate zones are compared. Included are myxobacterial species adapted to extreme biotopes. The efficiency of different methods used presently for isolation of myxobacteria is compared.

Fruiting myxobacteria from the South Carolina coast

Abstract: The widespread distribution of fruiting myxobacteria in the soil is fairly well known; however, there have never been reports on these bacteria isolated from the sand of an ocean beach. To
