of -C-CH3. The peak around 1 240 cm-1 is due to the vibration contribution from C-O-S stretching of sulfate, the C-O stretching of carboxyl or P=O stretching of phosphate. Another small peak......
and sulfur as the sole energy source, and a low level (0.1%, w/v) of peptone could accelerate the growth. It had a high ability of oxidating ferrous and sulfate. 3) Strain GF shared 99.64% identities......
station as the binder and indicated that the stabilization of Cr(Ⅵ) present in the waste required a reducing pretreatment with ferrous sulfate to attain toxicity characteristics leaching procedure(TCLP......
. The work on the sulfate reduction focused on (semi) extremophilic micro-organisms to extend the range under which this technology is applicable and to open new opportunities. The main work......
as follows[15-18]. 1) Ferric ion can dissolve these sulfide minerals (MS): MS+Fe3+Fe2++S0+M2+ 2) Bacteria can regenerate ferric iron: Fe2+-eFe3+ 3) The hydrolyzation of ferric sulfate can form......
