Biological Effect of EPS on Metal Sulfides

Wang Li Wen Jiankang Liu Meilin(National Engineering Laboratory of Biohydrometallurgy,Beijing General Research Institute for Nonferrous Metals)  
Based on the study of the role of extracellular polymeric substances(EPS)in biohydrometallurgy carried out both in and outside China,the paper summarizes the composition,structure,biosynthesis and characters of EPS and their biological effect on metal sulfides.EPS dissolves metal sulfides mainly through the oxidation effect of Fe3+ forming complex with the groups such as uronic acid residue group in EPS.
