Resumen:
This work studies the surface interaction between Thiobacillus ferrooxidans and Thiobacillus thiooxidans with crystalline and plastic elemental sulfur. The interaction mechanisms were analyzed by fractal geometry which describes textural modifications of the substrate caused by bacterial action. The results demonstrated that the bacteria are able to produce two different effects depending on the substrates. Only surface smoothing was detected on crystalline sulphur but, perforation of the bulk was also observed in plastic sulphur.
