Recent findings in deep surface microbiology, biocorrosion, acid mine drainage, and microbially induced mineral transformations have challenged the conventional concept of the exclusiveness or predominance of abiotic reactions in earth sciences. The potential of microorganisms for altering pH, Eh and chemical properties so as to allow transformation of metal-containing minerals led to new interest in the importance of microbes in geological processes. Metals cannot be degraded, but transformations through sorption or complexation with mineral surfaces, and/or changes in the valence state affect not only the mobility but also the bioavailability of these compounds.

最近在深地表微生物学、生物腐蚀、酸性矿山废水和微生物诱导的矿物转化方面的最新发现，对地球科学中非生物反应的排他性或优势的传统概念提出了挑战。微生物能够改变pH、Eh和化学性质，从而使含有金属的矿物发生转变，这使人们对微生物在地质过程中的重要性产生了新的兴趣。金属不能降解，但通过吸附或与矿物表面络合的转化和/或价态的变化不仅影响这些化合物的流动性，还影响其生物可利用性。
