Halothiobacillus neapolitanus (strain ATCC 23641 / c2) is a sulfur oxidizing chemoautotrophic Gram-negative bacterium isolated from a sulfide-rich natural spa. This organism is able to tolerate high concentrations of sulfide and fixes CO(2) using a polyhedral body called a carboxysome which contains the primary carbon fixing enzyme, ribulose bisphosphate carboxylase/oxygenase. The carboxysome is a polyhedral "organelles," made up entirely of protein. It plays important roles in microbial CO(2) sequestration. H.neapolitanus is the model organism for structural and functional studies of carboxysomes and plays important roles in the global biogeochemical carbon and sulfur cycles by virtue of its ability to satisfy its carbon and energy needs entirely with inorganic compounds (CO(2) and reduced sulfur compounds, respectively). It is found in a range of different environments, some of which can be classified as "extreme", and has gained notoriety as a biological agent that promote corrosion of concrete, acidification of mine tailings, and bioleaching of low-grade ores. It is also being tested in a variety of bioremediation efforts. (Adaptated from
