The Calvin-Benson-Bassham (CBB) cycle has been extensively studied in proteobacteria, cyanobacteria, algae and plants, but hardly at all in Gram-positive bacteria. Some characteristics of ribulose bisphosphate carboxylase/oxygenase (RuBisCO) and a cluster of potential CBB cycle genes in a Gram-positive bacterium are described in this study with two species of Sulfobacillus (Gram-positive, facultatively autotrophic, mineral sulfide-oxidizing acidophiles). In contrast to the Gram-negative, iron-oxidizing aciclophile Acidithiobacillus ferrooxidans, Sulfobacillus thermosulfidooxidans grew poorly autotrophically unless the CO2 concentration was enhanced over that in air. However, the RuBisCO of each organism showed similar affinities for CO2 and for ribulose 1,5-bisphosphate, and similar apparent derepression of activity under CO2 limitation. The red-type, form I RuBisCO of Sulfobacillus acidophilus was confirmed as closely related to that of the anoxygenic phototroph Oscillochloris trichoides. Eight genes potentially involved in the CBB cycle in S. acidophilus were clustered in the order cbbA, cbbP, cbbE, cbbL, cbbS, cbbX, cbbG and cbbT.
