“…However, to date, only a limited number of such models are available to describe bacterial adhesion in soil. The Langmuir equation has been a suitable model to describe the bacterial adhesion in soil in both the present results and those of previous studies (Hendricks et al, 1979;Jiang et al, 2007;Vasiliadou et al, 2011). Moreover, the unknown parameters (A max and k) in the Langmuir isotherm correlated well with the surface properties.…”

The initial adhesion of micro‐organisms on solid surfaces strongly affects their transport and fate in soil and aquatic environments. Experiments on Bacillus subtilis with various soil minerals (including kaolinite, montmorillonite, goethite, birnessite, quartz and mica) were conducted to determine the role of surface properties in adhesion and to test the validity of the extended Derjaguin, Landau, Verwey and Overbeek (DLVO) theory for bacterial adhesion. Adhesion of B. subtilis on all six minerals conformed to the Langmuir equation. Adhesion capacity and affinity showed a significant correlation with the specific external surface area (SESA) of the minerals and the calculated electrostatic energy barrier, respectively, but no significant correlation was observed between hydrophobicity and the adhesion parameters. These results demonstrate that adhesion capacity and affinity are primarily controlled by the SESA of the minerals and the surface electrical properties, respectively. The dependence of the adhesion capacity on SESA may be explained by the cell–mineral interaction model. Adhesion could be well predicted by the extended DLVO theory. The initial adhesion of bacteria with soil minerals can be evaluated by using independently measured surface properties of these components based on the extended DLVO theory combined with the Langmuir equation.

“…Microorganisms, which are often present at or near clay surfaces as these are enriched in ions and organic matter relative to AMD (Kostka et al, 2002;Theng and Orchard, 1995), promoted complex biogeochemical reactions in AMD sediments. Concurrently, bacterial coatings and biofilm formation (Konhauser and Urrutia, 1999;Dong et al, 2009;Vasiliadou et al, 2011;Mueller, 2015), which has been observed in the presence of clay minerals (Maurice et al, 2001a), including smectite (Alimova et al, 2009;Perdrial et al, 2009), could have protected clay surfaces from sustained acid attack and created microniches for optimal microbial processes.…”

Pollutants in acid mine drainage (AMD) are usually sequestered in neoformed nano- and micro-scale particles (nNP) through precipitation, co-precipitation, and sorption. Subsequent biogeochemical processes may control nNP stability and thus long-term contaminant immobilization. Mineralogical, chemical, and microbiological data collected from sediments accumulated over a six-year period in a coal-mine AMD treatment system were used to identify the pathways of contaminant dynamics. We present evidence that detrital nano- and micron-scale particles (dNP), composed mostly of clay minerals originating from the partial weathering of coal-mine waste, mediated biogeochemical processes that catalyzed AMD contaminant (1) immobilization by facilitating heterogeneous nucleation and growth of nNP in oxic zones, and (2) remobilization by promoting phase transformation and reductive dissolution of nNP in anoxic zones. We found that dNP were relatively stable under acidic conditions and estimated a dNP content of ~0.1g/L in the influent AMD. In the AMD sediments, the initial nNP precipitates were schwertmannite and poorly crystalline goethite, which transformed to well-crystallized goethite, the primary nNP repository. Subsequent reductive dissolution of nNP resulted in the remobilization of up to 98% of S and 95% of Fe accompanied by the formation of a compact dNP layer. Effective treatment of pollutants could be enhanced by better understanding the complex, dynamic role dNP play in mediating biogeochemical processes and contaminant dynamics at coal-mine impacted sites.

“…While some studies have examined interactions using mineral suspensions (e.g. Jiang et al, 2010;Parikh and Chorover, 2006;Rong et al, 2010;Vasiliadou et al, 2011), a number of studies have utilized mineral coatings (e.g. Fe-, Al-, Ti-oxides) on IREs in order to modify the surface chemistry of the substratum and examine sorption to a range of environmentally relevant surfaces (e.g.…”
