What's the difference between denitrification and denitrify?
Denitrification
Definition:
(n.) The act or process of freeing from nitrogen; also, the condition resulting from the removal of nitrogen.
Example Sentences:

(14) Comparison of the cell growth during denitrification indicated that the dissimilatory reduction of nitrate to nitrite is an energetically favorable process in F. oxysporum; however, further reduction of nitrite to N2O might be energy-exhausting and may function as a detoxification mechanism.
(15) The yields varied with sparging rates in agreement with a quantitative model of denitrification (Betlach, M. P., and Tiedje, J.M.
(16) Effects of illumination on the denitrification of nitrite were similar to those involving nitrate.
(17) Our observations provide evidence for a denitrification pathway in vivo of NO2(-)----NO----N2O, and N,N-bond formation catalyzed by NO reductase and not by cytochrome cd1.
(18) One of the reasons for this change is the process of denitrification due to changes in the hydrogeochemical conditions in a layer.
(19) The bulk of the denitrification activity was associated with the accumulation of NO3- in the oxidized surface zone of the sediment, but a secondary denitrification zone was occasionally found in the deeper layers where oxidized patches had been introduced by the burrowing activity of the macrofauna.
(20) Reports of the simultaneous use of oxygen and denitrification by different species of bacteria have become more common over the past few years.
Denitrify
Definition:
(v. t.) To deprive of, or free from, nitrogen.
Example Sentences:
(1) This denitrifying isolate is serologically unrelated to the comprehensively described Gram-negative obligately aerobic NTA-degrading bacteria all of which belong to the alpha-subclass of Proteobacteria.
(2) NCIB 11015, Achromobacter xylosoxidans GIFU 543); II, denitrifying bacteria in which cytochrome c' has not been found (Alcaligenes faecalis IAM 1015, Bacillus firmus NIAS 237, Pseudomonas stutzeri ATCC 17641); III, non-denitrifying bacterium containing cytochrome c' (A. xylosoxidans GIFU 1055).
(3) Numbers of proteolytic, nitrate assimilating, denitrifying, and cellulolytic bacteria were estimated.
(4) N2O uptake activity of cells and N2O reductase activity of the soluble fraction from denitrifying bacteria were assayed.
(5) Moreover, the separation time of most of the denitrifying bacteria from other non-denitrifying bacteria belonging to the same subgroup is recent.
(6) However, the remainder of the denitrifying pathway was constitutive and, like T. pantotropha, "Ps.
(7) The oxidation of cytochromes during the reduction of N2O to N2 by a denitrifying bacterium was studied spectrophotometrically.
(8) Suspensions of denitrifying cells of Pseudomonas perfectomarinus reduced nitrate and nitrate as expected to dinitrogen; but, in the presence of acetylene, nitrous oxide accumulated when nitrate or nitrate was reduced.
(9) The growth and survival of several rifampin-resistant isolates of denitrifying bacteria were examined under anaerobic (denitrifying) and aerobic conditions.
(10) Under anaerobic circumstances in the presence of nitrate Paracoccus denitrificans is able to denitrify.
(11) This pigment has not been reported previously for P. aeruginosa but it has been detected in other denitrifying bacteria including closely related Pseudomonas species.
(12) Nitrous oxide (N2O) respiration by the denitrifying bacterium Pseudomonas stutzeri requires the synthesis of the multi-copper enzyme N2O reductase, nosZ, the structural gene for this enzyme, is part of a DNA region of approximately 8 kbp that carries several essential genes.
(13) The number of ammonifiers and denitrifiers in the solution increased significantly by the end of plant vegetation; the amount of denitrifiers inhabiting the roots decreased during vegetation and that of ammonifiers increased.
(14) This strain seems to denitrify nitrite more rapidly than nitrate.
(15) Most probable number counts showed that denitrifying species were the numerically predominant NO3- reducing bacteria in the faeces of five methanogenic individuals [about 10(10) bacteria (g dry wt faeces)-1].
(16) Plasmid pCBI, carrying genes for the anaerobic degradation of benzoate in strain PN-1, is 17.4 kilobase pairs in length and is transmissible to a number of denitrifying Pseudomonas aeruginosa and Pseudomonas stutzeri strains.
(17) Polyclonal and monoclonal antibodies were raised against the nitrosating enzyme previously isolated and purified from a denitrifying bacteria Pseudomonas aeruginosa.
(18) A gas chromatographic method was used to demonstrate that nitrite can counteract the inhibition by azide of nitrous oxide reductase activity in denitrifiers.
