MDAG Case Study 17
Numerous references point out that T. ferrooxidans can accelerate the rate of sulphide oxidation, and thus the rate of acid generation, by one million times. If this ... discussed this in detail in a previous Internet Case Study, entitled Contribution of Bacteria to Sulphide-Mineral Reaction Rates in Natural Environments. Can the Gaia Theorem help to explain this? In our own ...
