“…Thus, there exist a variety of numerical models for reactive transport in porous media which involve microbial activity. Applications found in the literature include the interaction of microbes with the subsurface transport of contaminants, [e.g., 37,63,69,74], microbially enhanced oil recovery [e.g., 44,53,54,72], or biomineralization, of which especially the engineered application of MICP has received considerable attention. Most numerical models for MICP are, similarly to the model used in this study, formulated at the REV scale (or Darcy scale) [e.g., 2,17,46,51,[76][77][78], while [64] and [80][81][82] use pore-network and pore-scale models, respectively.…”
