Abstract
Publisher Summary This chapter focuses on the anaerobic respiration. Anaerobic respiration refers to the first group of chemosynthetic bacteria includes all those bacteria that perform energy-yielding reactions in which inorganic compounds other than oxygen act as terminal acceptor. It is an anaerobic process, which means that all bacteria carrying out this type of respiration are either strictly or facultative anaerobes. Three main groups of bacteria are known to use an inorganic compound as terminal electron acceptor: (1) Desulfovibrio or Desulfotomaculum, using sulfates as terminal electron acceptor; (2) the heterogeneous group of denitrifying bacteria, using nitrate as terminal electron acceptor; and (3) Methanobacterium, using carbon dioxide as terminal electron acceptor. The first two groups of bacteria are very closely related in their electron transport systems but differ in that the sulfate-reducing bacteria do not possess nicotinamide adenine dinucleotide. This difference in the electron transport systems also reflects that between the strictly anaerobic sulfate reducers and the facultative anaerobic group of denitrifiers.
