An in situ microcosm study of the influence of surface-adhering bacteria on silicate diagenesis in a shallow petroleum-contaminated aquifer showed that minerals were colonized by indigenous bacteria and chemically weathered at a rate faster than theoretically predicted. Feldspar and quartz fragments were placed in anoxic, organic-rich ground water, left for 14 months, recovered, and compared to unreacted controls with scanning electron microscopy. Ground-water geochemistry was characterized before and after the experiment. Localized mineral etching probably occurred in a reaction zone at the bacteria-mineral interface where high concentrations of organic acids, formed by bacteria during metabolism of hydrocarbon, selectively mobilized silica and aluminum from the mineral surface.
一项关于附着于表面的细菌对浅层受石油污染含水层中硅酸盐成岩作用影响的现场微观研究表明，细菌使矿物原地繁殖，并以比理论预测更快的速度发生化学风化。将长石和石英碎片置于缺氧、富含有机物的地下水中，放置 14 个月后回收，并通过扫描电子显微镜与未反应的对照物进行比较。在实验前后对地下水地球化学进行了特征描述。在细菌-矿物界面的反应区可能发生了局部矿物蚀刻，细菌在烃类代谢过程中形成的高浓度有机酸从矿物表面选择性地溶解了硅和铝。
