Comparison of denitrification by Pseudomonas stutzeri, Pseudomonas aeruginosa, and Paracoccus denitrificans.
A comparison was made of denitrification by Pseudomonas stutzeri, Pseudomonas aeruginosa, and Paracoccus denitrificans. Although all three organisms reduced nitrate to dinitrogen gas, they did so at different rates and accumulated different kinds and amounts of intermediates. Their rates of anaerobic growth on nitrate varied about 1.5-fold; concomitant gas production varied more than 8-fold. Ce...
متن کاملCell biology and molecular basis of denitrification.
Denitrification is a distinct means of energy conservation, making use of N oxides as terminal electron acceptors for cellular bioenergetics under anaerobic, microaerophilic, and occasionally aerobic conditions. The process is an essential branch of the global N cycle, reversing dinitrogen fixation, and is associated with chemolithotrophic, phototrophic, diazotrophic, or organotrophic metabolis...
متن کاملDetection of a nitrous oxide reductase structural gene in Rhizobium meliloti strains and its location on the nod megaplasmid of JJ1c10 and SU47.
The gene encoding a denitrification enzyme, nitrous oxide reductase (EC 1.7.99.6), in Rhizobium meliloti and other gram-negative bacteria was detected by hybridization to an internal 1.2-kb PstI fragment of the structural gene (nosZ) cloned from Pseudomonas stutzeri Zobell (W.G. Zumft, A. Viebrock-Sambale, and C. Braun, Eur. J. Biochem. 192:591-599, 1990). Homology to the probe was detected in ...
متن کاملThe requirement of RpoN (sigma factor sigma54) in denitrification by Pseudomonas stutzeri is indirect and restricted to the reduction of nitrite and nitric oxide.
The rpoN region of Pseudomonas stutzeri was cloned, and an rpoN null mutant was constructed. RpoN was not essential for denitrification in this bacterium but affected the expression levels and enzymatic activities of cytochrome cd1 nitrite reductase and nitric oxide reductase, whereas those of respiratory nitrate reductase and nitrous oxide reductase were comparable to wild-type levels. Since t...
متن کاملNitrate and nitrite control of respiratory nitrate reduction in denitrifying Pseudomonas stutzeri by a two-component regulatory system homologous to NarXL of Escherichia coli.
Bacterial denitrification is expressed in response to the concurrent exogenous signals of low-oxygen tension and nitrate or one of its reduction products. The mechanism by which nitrate-dependent gene activation is effected was investigated in the denitrifying bacterium Pseudomonas stutzeri ATCC 14405. We have identified and isolated from this organism the chromosomal region encoding the two-co...
