| Fixation of carbon dioxide into cell material is a prerequisite for biology and the evolution of early life forms. Bacteria living at the expense of inorganic compounds may represent the earliest forms of life, which evolved and existed under extreme conditions in the absence of molecular oxygen. Such a growth modus is a common trait of many bacteria of the kingdom Archaea living under extreme conditions. It is therefore interesting to study and compare their carbon dioxide fixation mechanisms. So far six different carbon fixation pathways have been disclosed. This contribution gives an overview on the variations found in autotrophic carbon fixation pathways. It tries to explain what the benefits of the different pathways are. It also addresses the question what may be the reason for the occurrence of such different biochemical solutions to one problem, i.e. to form one of the central carbon precursor metabolites from inorganic carbon. |
