The physiology of D. hafniense strain Y51 under close to natural conditions were examined: D. hafniense Y51 was subjected to a variety of limiting conditions (carbon or electron acceptor) or ammonium deprivation, in chemostat. Its physiology was assessed by transcriptomic and proteomic analyses and compared to that in batch culture. Electron donor/acceptor-limited growth conditions cause a switch to alternative metabolic pathways allowing the organism with a capacity to survive in polluted environments and with a readiness to use alternative electron acceptors such as PCE; (ii) nitrogen limitation induces nitrogen fixation implying a robustness vis-a-vis ammonia shortage; (iii) limiting conditions trigger a general stress response that should enable the organism to cope with even more environmental constraints.
