Anti-Corrosion Coating Utilizing Bacterial Precipated Exopolysaccharides

A method for inhibiting corrosion on corrosion-sensitive metal with a bacterial exopolysaccharide. Specifically, exopolysaccharides precipitated from NRRL bacterial strains coated on low carbon steel alloy provide anti-corrosion coating to corrosion sensitive metals. The corrosion rate for coated metal is less than 0.4 milli-inch per year.


•Bacterial exopolysaccharides are bio-based, environmentally benign, and cost comparative to existing anti-corrosion measures
• Exopolysaccharides are produced using readily available commercial fermentation processes



•Preventive measures that will reduce or eliminate corrosion of metals
