In the absence of oxygen, two different cultures of E.Coli are growing in a minimal medium- both with the same basiccomposition of standard salts, and both containing ammoniumchloride as the nitrogen source, and glucose as the carbon source.Only the first culture contains sodium nitrate in addition.
1) Describe the two metabolic pathways in the twodifferent cultures and put them in to a global perspective. To whatnutrients cycles do they contribute, and how?
2) what are some of the major groups of environmentalbacteria that use these pathways? Describe them briefly. What aretypical habits where these pathways play an importantrole?
