Habitat
Lysobacter spp. have been described as ubiquitous inhabitants of soil and water. Their presence has been largely ignored, since members often are minor components in sample screenings when using conventional isolation procedures. However, because of improved molecular methods of identification and better descriptions for the genus, their agricultural relevance is becoming increasingly evident especially as members of ecologically significant microbial communities associated with soil and plants. Recent evidence suggests that Lysobacter spp. may occupy a wide range of ecological niches beyond those associated with plants, including a broad range of ‘extreme’ environments. For example, 16S rDNA phylogenetic analyses show Lysobacter clades that include sequences obtained from hydrothermal vents, isolates from Mt. Pinatubo mud flows and upflow anaerobic blanket sludge reactors, and an iron-oxidizing, microaerophilic lithotroph.
Lysobacter gummosus was discovered living on the skin of redback salamanders and producing 2,4-diacetylphloroglucinol, a chemical which inhibits the growth of certain pathogenic fungi.

Famous quotes containing the word habitat:
“Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.”
—William James (1842–1910)
“Nature is the mother and the habitat of man, even if sometimes a stepmother and an unfriendly home.”
—John Dewey (1859–1952)
