Mode of Action
Acidithiobacillus thiooxidans employs a multi-enzyme network to oxidize reduced inorganic sulfur compounds (RISCs) into sulfate:
Elemental Sulfur Oxidation: Sulfur dioxygenase (SDO) and sulfur oxygenase reductase (SOR) convert S⁰ to sulfite and thiosulfate.
Thiosulfate Pathways:
Sox system oxidizes thiosulfate directly to sulfate.
Thiosulfate: quinone oxidoreductase (TQO) generates tetrathionate, subsequently hydrolyzed by tetrathionate hydrolase (TetH).pmc.ncbi.nlm.nih
Sulfide Oxidation: Sulfide:quinone oxidoreductase (SQR) catalyzes sulfide to elemental sulfur or polysulfide, feeding into other oxidation routes.
Sulfite to Sulfate: Periplasmic sulfite oxidase (SOX) finalizes the conversion to sulfate, releasing protons that acidify the environment and mobilize metals.

FAQ
What is Thiobacillus thiooxidans used for?
It oxidizes elemental sulfur into plant-available sulfate, serves in biofertilizers for S-deficient soils, and drives bioleaching of metals from ores and wastes.link.springer+1
Where is Acidithiobacillus ferrooxidans found?
A. ferrooxidans thrives in acid mine drainage, sulfide-rich soils, and industrial effluents, often co-existing with A. thiooxidans in biomining environments.linkinghub.elsevier
What does Thiobacillus ferrooxidans do?
It oxidizes Fe²⁺ to Fe³⁺ via rusticyanin and cytochromes, acidifies its environment, and solubilizes iron and other metals for agricultural and industrial applications.universalmicrobes
Is Thiobacillus ferrooxidans harmful or beneficial?
Beneficial for bioleaching and soil micronutrient mobilization, but its acid production can accelerate concrete corrosion and acidify effluents if unmanaged.e3s-conferences
How does Thiobacillus thiooxidans help in bioleaching?
By producing sulfuric acid through sulfur oxidation, it lowers pH, solubilizes metal sulfides, and enhances metal recovery from ores and industrial wastes.linkinghub.elsevier
Can Thiobacillus species improve soil fertility?
Yes—by oxidizing sulfur compounds to sulfate, they sustain plant sulfur nutrition, stimulate microbial diversity, and improve soil structure and nutrient cycling.link.springer
Are Thiobacillus bacteria used in wastewater treatment?
They are employed for desulfurization and heavy metal removal in tannery, municipal, and industrial wastewaters via sulfur oxidation and acidification processes.hindawi+1
