Short summary
This paper contributes to the study of bacterial carbon sequestration in mine tailings. Previous studies focused on carbonate mineral precipitation, while the role of autotrophs in carbon sequestration has been neglected. Carbon sequestration in two mine tailings treated with FeS2 was analyzed using 13C isotope labeling, pyrosequencing, and DNA SIP to identify carbon fixers. This paper is the first to investigate carbon sequestration by autotrophic groups in mine tailings.
