Abstract

Bacterial anaerobic respiration is one of the most ancient and essential metabolism processes, possessing the characteristics of both flexibility and high diversity, and a very close relationship with the physiological function in the ecological environment. Under anaerobic conditions, bacteria and anthropogenic substances can form coupling process facilitating terminal electron transfer. Several forms of bacterial anaerobic respiration and electron transfer related to the biotransformation of pollutants, including respiration with humics, sulfonates, halogenated chemicals, azo compounds, TNTs, metallic and non-metallic elements, are reviewed in this paper. These respirations and electron transfers on diverse electron acceptors in the environment have important biotechnological implications because these biochemical reactions have their roles on the transformation/degradation of toxic substances and the cycling of organic carbon as well as many inorganic elements. Furthermore, remediation of sites contaminated with toxic pollutants based on bacterial anaerobic respirations is being recognized widely.
