Phylogeny and Classification

Our current knowledge about myxobacteria has been summarized repeatedly in recent years. We would like to draw the reader s attention to two excellent and comprehensive book chapters by Shimkets et al. [5] and Reichenbach [6], which should be consulted for additional details. These references were also used here as information source for summarizing aspects of myxobacterial phylogeny, physiology, and growth/nutrient requirements (see Sections 12.2-12.4.). 

Myxobacteria are generally regarded as mesophilic and strictly aerobic soil microorganisms exhibiting a temperature optimum between 26 and 34°C [2]. 

dehalogenans is currently the only facultative anaerobe classified within the order Myxococcales [21] (see Section 12.2). In antarctic soil samples, psy-chrophilic species were found growing at low temperatures of 4-9 °C only [22]. 

A prominent metabolic feature of myxobacteria besides their extensive secondary metabolism (see Section 12.6) is their ability to specifically decompose
