Microbial Community Structure and Functions in Ethanol-Fed Sulfate Removal Bioreactors for Treatment of Mine Water

Autor: Malin Bomberg, Jarno Mäkinen, Marja Salo, Mona Arnold

Publikováno v: Microorganisms, Vol 5, Iss 3, p 61 (2017)

Sulfate-rich mine water must be treated before it is released into natural water bodies. We tested ethanol as substrate in bioreactors designed for biological sulfate removal from mine water containing up to 9 g L−1 sulfate, using granular sludge f
