“…However, substrate fermentation and OHR generate acids, which acidify the groundwater. This drastically inhibits OHR, as OHRB are inactivated at decreased pH (Lacroix et al 2014b). Circulation of sodium bicarbonate or sodium carbonate solutions is commonly used to adjust the pH of groundwater during OHR (Robinson et al 2009).…”

In natural and engineered environments, microorganisms often co-exist and interact with various minerals or mineral-containing solids. Microorganism-mineral interactions contribute significantly to environmental processes, including biogeochemical cycles in natural ecosystems and biodeterioration of materials in engineered environments. In this mini-review, we provide a summary of several key mechanisms involved in microorganism-mineral interactions, including the following: (i) solid minerals serve as substrata for biofilm development; (ii) solid minerals serve as an electron source or sink for microbial respiration; (iii) solid minerals provide microorganisms with macro or micronutrients for cell growth; and (iv) (semi)conductive solid minerals serve as extracellular electron conduits facilitating cell-to-cell interactions. We also highlight recent developments in harnessing microbe-mineral interactions for biotechnological applications.
