摘要：
Disclosed is a method for inhibiting corrosion on corrosion-sensitive metal with a bacterial exopolysaccharide. Specifically, exopolysaccharides precipitated from NRRL bacterial strains B-1254, B-1355, B-1498, and B-1500 coated on low carbon steel alloy confers anti-corrosion coating to corrosion sensitive metals. Preferably with the coating, the corrosion rate for coated metal is less than 0.4 milli-inch per year.
