SUMMARY:How can surface interactions of bacteria and natural soil particles
  help improve remediation practices?
DESCRIPTION:Natural surfaces such as clay minerals and oxides are key playe
 rs in the physicochemical interaction between microorganisms and their env
 ironment. The presence of clay particles has been reported to enhances bac
 terial viability by providing minerals and nutrients and/or by stimulating
  the creation of biofilms. However\, the interactions of bacteria and clay
  minerals is not trivial because bacteria and clays are usually both negat
 ively charged and therefore\, must overcome a potential energy barrier to 
 interact. Here we will discuss possible interaction pathways of bacteria a
 ttachment to clay minerals and their impact on bacterial activity. Specifi
 cally\, we explore the effect of solution chemistry and attachment-enhanci
 ng membrane appendages such as amyloids. The knowledge gained from these s
 tudies can then aid in immobilization of bacteria for different pollution 
 mitigation and remediation strategies. Two examples of such clay-bacteria 
 complexes will be presented: 1). Cyanobacteria complexation with natural a
 nd modified clays to prevent and treat algal blooms and\, 2). The design o
 f bacteria-polymer-clay composites for the adsorption and fast degradation
  of formaldehyde from industrial waste-streams. These sustainable and low-
 cost platforms have the potential to improve and advance remediation syste
 ms that are currently of difficult to treat.\n\nAbstract
