Our goal is to understand how microbial behavior influences the mechanical stability of illuminated littoral marine sediments. We define behavior as the interaction of bacteria and diatoms with environmental signals that are either auto-produced, or arise from another source. A further goal is to investigate whether these processes, which define sediment optical signatures, can be influenced by anthropogenic intervention. Our objectives are to isolate representative bacteria and diatoms from stabilized sediments and use these organisms in axenic and defined mixed cultures to examine the microbially-driven sediment aggregation process in vitro. The surficial chemistry necessary for adhesion is an important variable in sediment particle colonization by microorganisms. We will measure the influence of this parameter on the adhesion process as well as the possibility for cellcell interaction in the attached cell layer.
