Transcription profiling of E. coli TG1/pBS(Kan)Synhox and pBS(Kan) ability to produce hydrogen


ABSTRACT: E. coli TG1 with pBS(Kan)Synhox can produce more hydrogen than TG1/pBS(Kan). To reveal the difference of metabolic activity (gene expression) between these strains in producing hydrogen, the differential gene expression analyses were performed. All samples cultured in complex medium with fructose containg 5 mM IPTG. Experiment Overall Design: Strains: E. coli TG1/pBS(Kan)Synhox and TG1/pBS(Kan) Experiment Overall Design: Medium: Complex with fructose Experiment Overall Design: Hydrogen producing cells Experiment Overall Design: Time: 6 hour

<h4>Background</h4>Molecular hydrogen is an environmentally-clean fuel and the reversible (bi-directional) hydrogenase of the cyanobacterium Synechocystis sp. PCC 6803 as well as the native Escherichia coli hydrogenase 3 hold great promise for hydrogen generation. These enzymes perform the simple reaction 2H+ + 2e- <--> H2 (g).<h4>Results</h4>Hydrogen yields were enhanced up to 41-fold by cloning the bidirectional hydrogenase (encoded by hoxEFUYH) from the cyanobacterium into E. coli.
