Coupled Microbial and Transport Processes in Soils

Abstract: 1992b; MacDonald et al., 1999a, 1999b). Almost all previous work on this topic has focused on liquid-saturated This paper reviews methods for modeling coupled microbial and porous media systems, with relatively few attempts at transport processes in variably saturated porous media. Of special interest in this work are interactions between active microbial growth addressing more complicated unsaturated or variably satand other transport processes such as gas diffusion and interphase urated systems. This lack of… Show more

“…The potential interactions between microorganisms and HA have been previously reported with soils well suspended and colloids rapidly formed under some forces [25][26][27]. Bearing in mind these results, HA with amphimorphic characteristics was used to suspend and stabilize soil colloids and microorganisms were supplied to reduce surface tension.…”

“…Generalisations to multi-species microbial reactive transport are straightforward, but are not discussed further here. Transport equations for the bacteria, nutrient and bio-product in the aqueous phase (Rockhold et al 2004;Kim 2006) are written as…”

“…where C b , C n and C p are the concentrations of bacteria, nutrients+substrates and metabolic products, respectively; D b , D n and D p are dispersion tensors for bacteria, nutrients+sub-strates and metabolic products, respectively; u w is the Darcy flux vector for the water phase, V g is the settling velocity vector of bacteria and R b , R n , R p are the reaction rate source/sink terms as defined by (Rockhold et al 2004;Kim 2006)…”
