    Sulfur-driven autotrophic denitrification: Diversity, biochemistry, and engineering applications

    No full text
    Sulfur-driven autotrophic denitrification refers to the chemolithotrophic process coupling denitrification with the oxidation of reduced inorganic sulfur compounds. Ever since 1904, when Thiobacillus denitrificans was isolated, autotrophic denitrifiers and their uncultured close relatives have been continuously identified from highly diverse ecosystems including hydrothermal vents, deep sea redox transition zones, sediments, soils, inland soda lakes, etc. Currently, 14 valid described species within α-, β-, γ-, and ε-Proteobacteria have been identified as capable of autotrophic denitrification. Autotrophic denitrification is also widely applied in environmental engineering for the removal of sulfide and nitrate from different water environments. This review summarizes recent researches on autotrophic denitrification, highlighting its diversity, metabolic traits, and engineering applications. © 2010 Springer-Verlag.link_to_subscribed_fulltex

    The Trap of Intellectual Success. Robert N. Bellah, the American Civil Religion Debate, and the Sociology of Knowledge

    No full text
    Current sociology of knowledge tends to take for granted Robert K. Merton\u2019s theory of cumulative advantage: successful ideas bring recognition to their authors, successful authors have their ideas recognized more easily than unknown ones. The paper argues that this theory should be revised via the introduction of the differential between the status of an idea and that of its creator: when an idea is more important than its creator, the latter becomes identified with the former, and this will hinder recognition of the intellectual\u2019s new ideas as they differ from old ones in their content and/or style. Robert N. Bellah\u2019s performance during the \u201ccivil religion debate\u201d of the 1970s is reconstructed as an example of how this mechanism may work. Implications for further research are considered in the conclusive section
