Growth on Hydrogen by the Sulfate-Reducing <i>Oleidesulfovibrio alaskensis</i> Induces Biofilm Dispersion and Detachment─Implications for Underground Hydrogen Storage.

ABSTRACT: Hydrogen is a versatile energy carrier for human activity but is also a ubiquitous electron donor for subsurface microorganisms. During underground hydrogen storage operations, it is expected that microbial communities will use the injected hydrogen as electron donor for diverse metabolisms, and induce a variety of microbial-triggered risks. A significant concern is the formation of biofilm and induced bioclogging, which may reduce the hydrogen injectivity and storage operation efficiency by altering the subsurface hydrogen flow. This study investigates how different electron donors─specifically hydrogen and lactate─affect the growth dynamics of a sulfate-reducing bacterium (Oleidesulfovibrio alaskensis G20) and the associated biofilm formation in porous media. The pore-scale observ
