Two-component transcriptional regulation of N-acyl-homoserine lactone production in Pseudomonas aureofaciens
Article Abstract:
Bacterial populations require precise gene expression regulation as a means of responding to changing environmental conditions. Two-component signal transduction systems facilitate bacterial gene expression regulation. Both systems are composed of a sensor kinase and a cytoplasmic response regulator. GacS/GacA are also present and serve as controllers of phenazine production in an AHL-independent environment. Results of the study were based on AHL preparations derived from 5-ml cultures of Pseudomonas strains that were grown overnight at 28 deg Celcius with shaking in PPMD broths.

Validation of microcosms for examining the survival of Pseudomonas aureofaciens (lacZY) in soil
Article Abstract:
An intact soil core appears to accurately predict the survival of recombinant microorganisms in the environment. Pseudomonas aureofaciens (lacZY) inoculated into 5 by 15 cm polyvinyl chloride cores containing either bulk or rhizosphere soil exhibited survival similar to that seen in the field. Inoculum in 50 g of dried and sieved (disturbed) soil did not accurately predict survival. The simple, cheap intact core may provide a standard environmental microcosm for risk assessment of recombinant microbes.

Fate of the biological control agent Pseudomonas aureofaciens TX-1 after application to turfgrass
Article Abstract:
Applying the biological control agent Pseudomonas aureofaciens TX-1 to turfgrass does not substantially affect the indigenous microbial population. This bacterium produces the antimicrobial compound phenazine-1-carboxylic acid and is used to control soil fungi.
