Thiosulphate oxidation by Thiobacillus thioparus and Halothiobacillus neapolitanus strains isolated from the petrochemical industry

Sulphur Oxidizing Bacteria (SOB) is a group of microorganisms widely used for the biofiltration of Total Reduced Sulphur compounds (TRS). TRS are bad smelling compounds with neurotoxic activity which are produced by different industries (cellulose, petrochemical). Thiobacillus thioparus has the capa...

In this study, two thiosulphate oxidizing strains were isolated from a petrochemical plant (ENAP BioBio, Chile).

Real time PCR and 16S rDNA sequencing showed that one of the isolated strains belonged to the Thiobacillus branch.
