The attachment of diatoms to surfaces is an important and poorly understood step in the development of biofouling communities. Experiments were performed in vitro on a common fouling diatom (Achnanthes longipes) to determine the influence of the base material and bacterial conditioning on diatom attachment. The first series of experiments compared...

... These initial biofilm organisms are known to produce exopolymers that assist the process of adhesion and movement (Molino and Wetherbee, 2008). So, the observed pattern of biofilm community development in natural systems (bacteria preceding algae) is more likely to be a reflection of the average abundance and the availability of the different colonizing forms at the moment of immersion of a new substratum (Gawne et al., 1998;Wahl, 1989). In view of this, considering the cell size, cell availability and cell abundance, since picophytoplankton are next to bacteria, it was hypothesized that picophytoplankton are the first autotrophic colonizers in biofilms contributing significantly to the biofilm photosynthetic biomass in the initial stages thereby playing an important role in the biofilm food web dynamics and probably in the production of exopolymers similar to bacteria and diatoms (Patil and Anil, 2005c). ...
