The role of iron oxidizing bacteria to the quality of leachate on acid sulphate soil
The problem encountered in acid sulphate soil is the presence of pyrite (FeS2) which causes soil to have highly acid reaction when the pyrite is oxidized.

Polythionate degradation by tetrathionate hydrolase of Thiobacillus ferrooxidans [PDF]
Cell-free extracts of Thiobacillus ferrooxidans grown with thiosulfate as energy source and prepared at high ammonium sulfate concentrations and at low pH are capable of polythionate hydrolysis. The enzyme responsible for the hydrolysis of tetrathionate (S4O2- 6) and pentathionate (S4O2- 6) was purified to ...

Sulfur-binding protein of flagella of Thiobacillus ferrooxidans [PDF]
The sulfur-binding protein of Thiobacillus ferrooxidans ATCC 23270 was investigated. The protein composition of the bacterium's cell surface changed according to the culture substrate. Sulfur-grown cells showed greater adhesion to sulfur than iron-grown cells. The sulfur-grown cells synthesized a 40-kDa surface protein which was not synthesized by iron-

Plant growth–promoting rhizobacteria (PGPR) are beneficial soil bacteria that colonize the rhizosphere and enhance plant growth through direct and indirect mechanisms, including nutrient solubilization, phytohormone production, suppression of phytopathogens, and activation of plant defense mechanisms.

Nitrogen Fixation by Thiobacillus ferrooxidans [PDF]
Summary: Cultures of Thiobacillus ferrooxidans grown in the absence of a source of fixed nitrogen reduced acetylene to ethylene suggesting the presence of nitrogenase. This presumptive evidence has now been substantiated by the demonstration of the enrichment of 15N in the protein of the organism when grown under 15N2.
