Bacterial respiration: a flexible process for a changing environment
Article Abstract:
The respiratory flexibility of bacteria permits them to live in almost every environment on Earth, including hostile and anoxic ones. Bacteria can use a diverse number of electron acceptors, including sulfur and its oxyanions, organic sulfoxides and sulfonates, nitrogen oxyanions and nitrogen oxides, organic N-oxides, halogenated organics, selenate and arsenate oxyanions, transition metals and radionuclides.

Cadmium-specific formation of metal sulfide 'Q-particles' by Klebsiella pneumoniae
Article Abstract:
Research shows that the organism Klebsiella pneumoniae is capable of resisting cadmium toxicity by the formation of metal sulfide particles at the surface of the cell. Clumps of tiny metal sulfide particles of approximately four nanometers in diameter are observed using electronic absorption spectroscopy when K. pneumoniae are grown in the presence of cadmium. The reaction appears to be cadmium-specific.

Supply of O(sub)2 regulates demand for O(sub)2 and uptake of malate by N(sub)2-fixing bacteriods from soybean nodules
Article Abstract:
Results show that the malate transport is tightly coupled to respiratory process of the bacteroids, which in turn is regulated by oxygen supply during nitrogen fixation by the bacteriods. Data indicate that free oxygen in the ambient of the reaction chamber has no influence.
