Luteimonas mephitis is a type of bacteria . It is one of the proteobacteria .
Appearance
The cells of Luteimonas mephitis are rod-shaped. The width is between 0.4 and 0.6 μm and the length between 0.8 and 1.8 μm. The colonies are colored yellow. There are no flagella .
metabolism
The metabolic pathway of Luteimonas mephitis is based on breathing . The bacterium is heterotrophic . Oxygen is the terminal electron acceptor. The gram test turns out negative.
The bacterium reduces nitrite to nitrous oxide (H 2 N) ( denitrification ). The species does not reduce nitrate. The fact that nitrous oxide rather than nitrogen (N 2 ) is formed during the denitrification of nitrite is an important distinguishing feature from other genetically similar species. Tween 80 is hydrolyzed by the bacterium . Esculin is not hydrolyzed. Also, lecithin is not degraded.
Luteimonas mephitis was on antibiotics tested and is resistant to erythromycin , streptomycin , nalidixic acid , ampicillin and penicillin G . The bacterium is not pathogenic, however .
Chemotaxonomic Features
The dominant quinone is at Luteimonas mephitis to ubiquinone-eighth The dominance of branched-chain, odd-numbered fatty acids is unusual . The presence of branched fatty acids and the presence of ubiquinone-8 is also a typical feature of the closely related genera Stenotrophomonas and Xanthomonas . The reduction of nitrite to nitrous oxide (N 2 O) without the release of nitrogen (N 2 ) does not occur in these species and is an important distinguishing feature.
The two most common fatty acids are iso -C 15: 0 , iso -C 17: 1, cis -9 and iso -C 17: 0
Systematics
Luteimonas mephitis was first described in 2000 by Wolfgang Finkmann, Karlheinz Altendorf, Erko Stackebrandt and André Lipski. It is the first described species of the genus Luteimonas , so it is the type species of this genus.
Luteimonas was first assigned to the Xanthomonadaceae family . As a result of further phylogenetic examinations and analyzes of the rRNA, the family was dissolved in 2015 and the species it contained were placed in other families. Luteimonas mephitis is now placed in the family Lysobacteraceae of the order Lysobacterales . This order in turn belongs to the class of the Gammaproteobacteria .
etymology
The generic name Luteimonas is derived from the Latin adjective luteus (yellow) and the Greek word monas (unit). The species name L. mephitis is based on the name of the Italian goddess for sulphurous and unpleasant smells Mephitis . The bacterium was isolated from a biofilter for waste gas treatment.
