In situ detection of representatives of the genus Acidovorax in activated sludge of a sewage treatment plant (Munchen I, Großlappen). Viewed by epifluorescence microscopy. The fixed sample was simultaneously hybridized with the Cy3-labeled probe ACI145. Bar indicates 10 microns. - Source:10

POSNEGVariableNot assessed


Acetate-utilizing denitrifiers in activated sludge 11. Cells are straight to slightly curved rods occurring singly, in pairs, or in short chains 12 24. Acidovorax are aerobic, chemoorganotrophs, although some strains of two species (A. delafieldii and A. temperans) are able to grow anaerobically using nitrate as terminal electron acceptor 12 24. Autotrophic growth is possible for strains of two species (A. facilis and A. delafieldii) where oxidation of hydrogen is used as an energy source 12 13 24. In activated sludge, Acidovorax* have been demonstrated to denitrify with acetate 11.
