Application

EC Number Application Comment Organism
1.13.11.55 industry Acidithiobacillus caldus is widely used in bio-leaching. It gains energy and electrons from oxidation of elemental sulfur and reduced inorganic sulfur compounds (RISCs) for carbon dioxide fixation and growth. Its sulfur oxidation system involves a truncated sulfur oxidation (Sox) system (omitting SoxCD), nonSox sulfur oxidation system similar to the sulfur oxidation in A. ferrooxidans, and sulfur oxygenase reductase (SOR) Acidithiobacillus caldus
