Characterization of extracellular polymeric substances from denitrifying organism Comamonas denitrificans.

abstract：:Proteins that catalyze H2-pathways often contain iron-sulfur (Fe-S) clusters and are sensitive to O2. We tested whether deletion of the gene encoding the transcriptional negative regulator, IscR, could enhance the ability of Escherichia coli BL21 to synthesize active recombinant H2-pathway components and stimulate fer...
