The invention provides partially purified EPS that was purified from Thauera sp. Strain MZ1T. This partially purified EPS comprises rhamnose, xylose, galacturonic acid, galactose, glucose, N-acetylfucosamine. The invention further provides methods of producing the partially purified EPS and of utilizing the partially purified EPS in methods of chelating metals. Further provided by this invention is an exopolysaccharide termed "thaueran" that was purified from Thauera sp. Strain MZ1T. This exopolysaccharide has a molecular weight of about 250 kDa and comprises rhamnose, galacturonic acid, N-acetylfucosamine and N-acetylglucosamine. The invention also provides methods of producing the exopolysaccharide and of utilizing the exopolysaccharide in methods of chelating metals.
