In sulphur cycle Sulphate Reducing Bacteria (SRB) have an important role and therefore in wastewater treatment system, they are able to form biofilms on metallic surfaces, leading to fouling and corrosion problems. Though last two decades researchers have discovered that SRB can, infact, tolerate and even respire oxygen. In this study the SRB biofilms were discovered in order to evaluate surface effect on biofilms formation.

The present investigation results showed that the biofilms formed on stainless steel presented higher metabolic activity, confirmed by lactate and sulphate removals. Studies performed with suspended cultures of Desulfovibrio desulfuricans also showed that the presence of Ni in the media have the positive impact on bacterial activity. This will show satisfactory results in wastewater treatment plants of the industries.
