Application

Application Comment Organism
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

Protein Variants

Protein Variants Comment Organism
additional information generation of an enzyme mutant lacking the sulfur oxygenase reductase gene sor, comparative transcriptome analysis, microarrays and real-time quantitative PCR, of the wild-type and the DELTAsor mutant, growth analysis on sulfur or K2S4O6 as the sole substrates reveals that the mutant has an obvious growth advantage compared to the wild-type strain and its maximum cell concentration is 70% higher than the wild-type, overview Acidithiobacillus caldus
