Microbial transformations of fossil organic matter of kupferschiefer black shale – elements mobilization from metalloorganic compounds and metalloporphyrins by a community of indigenous microorganisms

The presented article describes the role of community of indigenous microorganisms occurring in the Kupferschiefer black shale in elements mobilization from fossil organic matter of the deposit. The short description of metalloorganic compounds and metalloporphyrins extracted from black shale was presented as well as the characterization of indigenous microorganisms. The processes of fossil organic matter colonization, biofilm development and elements mobilization accompanying bacterial growth was summarized.
