Carbon supply and 2-oxoglutarate effects on expression of nitrate reductase and nitrogen-regulated genes in Synechococcus sp. strain PCC 7942.

abstract：:Eikenella corrodens 33EK(L), a clinical isolate, was assayed for its ability to utilise amino acids as substrates in the reduction of nitrate to nitrite. The metabolism of proline, glutamate, serine and glutamine was found to result in relatively high rates of nitrate reduction. The ability of cells to metabolise thes...
