Energetic consequences of nitrite stress in Desulfovibrio vulgaris Hildenborough, inferred from global transcriptional analysis
Article Abstract:
Desulfovibrio vulgaris Hildenborough was used as a model organism to study stress response to nitrite, an important intermediate in nitrogen cycle in order to understand the metabolism of microorganisms under adverse environmental conditions for improved bioremediation efforts. Global trnscription profiling with whole-genome microarays revealed coordinated cascades of responses to nitrite in pathways of energy metabolism, nitrogen metabolism, oxidative stress response and iron homeostasis.

Temporal transcriptomic analysis as Desulfovibrio vulgaris hildenborough transitions into stationary phase during electron donor depletion
Article Abstract:
Stasis-induced genes and gene networks as Desulfovibrio vulgaris transitioned from the exponential phase to the stationary phase are studied. The results demonstrate that the gene expression profiles of D. vulgaris cells changed in response to carbon and energy depletion and that gene expression during the stationary phase was not static.

Flux analysis of central metabolic pathways in Geobacter metallireducens during reduction of soluble Fe (II)-nitrilotriacetic acid
Article Abstract:
The carbon fluxes in the central metabolism of Geobacter metallireducens strain GS-15 were analyzed using [super 13]C isotopomer modeling. The results indicated that Geobacter metallireducens strain GS-15 utilizes the complete TCA cycle to oxidize acetate to C[O.sub.2] while reducing soluble Fe(III)-nitrilotriacetic acid.
