Are Denitrifying Bacteria Chemoautotrophs?

The nitrifying bacteria are chemoautotrophs and are able to use this source of energy to produce organic compounds from inorganic ones (photo-autotrophs use light energy to produce organic compounds from inorganic ones).

Which is a denitrifying bacterium?

Thiobacillus denitrificans, Micrococcus denitrificans, and some species of Serratia, Pseudomonas, and Achromobacter are implicated as denitrifiers. Pseudomonas aeruginosa can, under anaerobic conditions (as in swampy or water-logged soils), reduce the amount of fixed nitrogen (as fertilizer) by up to 50 percent.

Are denitrification bacteria heterotrophic?

Denitrifying bacteria are an essential component in treating wastewater. ... Since denitrifying bacteria are heterotrophic, an organic carbon source is supplied to the bacteria in an anoxic basin. With no available oxygen, denitrifying bacteria use the oxygen present in the nitrate to oxidize the carbon.
