(15) Thiosphaera pantotropha thus is similar to other heterotrophic nitrifiers-denitrifiers in that it conserves energy while denitrifying but has not been observed to do so when heterotrophically nitrifying.

Nitrite
Definition:
(n.) A salt of nitrous acid.
Example Sentences:

(2) Optical difference spectroscopy was used to investigate the kinetics of product formation during the reaction of the respiratory chain with nitrite.
(3) Total bacterial counts, nitrate-reducing bacteria and nitrite concentration were determined in fasting gastric juice before and after 4 weeks of treatment with a strong or with a mild antacid drug, a placebo preparation and the spasmolytic agent papaverine which is known to inhibit gastric evacuation.
(4) This would explain why the presence of ammonium sulphate appreciably offsets the effects of decreasing pH and also the exponential relationship between rate of nitrite loss and ammonium sulphate concentration.
(5) For comparison we investigated several structural analogues with respect to their nitric oxide or nitrite ion releasing potency.
(6) Our observation leads to the suggestion that, in vivo, either rhodanese is maintained in its more stable sulfur-substituted form or cellular compartmentalization prevents inactivation by nitrite.
(7) Sodium nitrite, a substance with unknown promoting activity, effectively uncoupled cells.
(8) The tricyclic psychotropic drug opipramol (Insidon) reacts in vitro with sodium nitrite in acidic solution to form products including mutagens for Salmonella typhimurium TA98 and TA100.
