Figure 4From: Genes and pathways for CO2 fixation in the obligate, chemolithoautotrophic acidophile, Acidithiobacillus ferrooxidans, Carbon fixation in A. ferrooxidansOrganization of gene clusters involved in the CBB cycle of facultative and obligate autotrophic α-, β- and γ-proteobacteria presented as a phylogenetic cladogram based on 16 S RNA. Numbers refer to bootstrapping results from 1000 trees. Organism names are provided in the text. The asterisk indicates that the respective organism is an obligate autotroph.Back to article page
