|Paucimonas (Pseudomonas) lemoignei|
Phylum Proteobacteria, Class Gammaproteobacteria, Order Pseudomonadales, Family Pseudomonadaceae, Genus Pseudomonas,
Pseudomonas lemoignei Delafield et al. 1965.
Moved to Genus Paucimonas as Paucimonas lemoignei Jendrossek 2001.
Gram-negative rods, 0.75 x 1.6-2.6 µm. Motile by a single polar flagellum. Accumulate
poly-beta-hydroxybutyrate as intracellular carbon reserve. Endospores not produced.
Colonies are small and adherent to agar. On complex media or media with tyrosine
colonies may become brown to black. Fluorescent pigment is not produced. Strictly
aerobic, growth temperature 30 ºC. No growth observed at 41 ºC. Does not grow well
on complex media and the addition of yeast extract to mineral media containing
a suitable carbon source does not improve the growth.
Isolated from soil by enrichment in mineral medium with poly-β-hydroxybutyrate as sole carbon source.
