Abstract: The study aims at determination of corrosion rate reduction in water by uptake of dissolved oxygen by Rhodotorula mucilaginosa. Corrosion of mild steel in water due to oxygen is a common phenomena in cooling towers and process industries. Dissolved oxygen uptake at various pH -acidic, neutral and alkaline conditions indicated that corrosion reduced at pH 7. The uptake of ferrous ions by Rhodotorula mucilaginosa was detected by Atomic Absorption Spectrometry (AAS). The affinity for uptake of cadmium ions by Rhodotorula mucilaginosa in presence of ferrous ions was confirmed by AAS. Both weight loss and electrochemical method gave analogous data in corrosion reduction for Thane creek water.
