Abstract : Diatoms form a major part of the fouling film on wetted and illuminated surfaces. The process by which this takes place is hypothesized to occur as follows: (a) diatoms arrive at a surface by purely hydrodynamics means, (b) at the surface receptor activation of adhesive synthesis is initiated and the adhesive is packaged into vesicles, (c) the vesicles are transported to the raphe where they fuse with the plasma membrane allowing adhesive to interact with the substration, (d) the secretory process is mediated by changes intracellular calcium concentrations. Cell surface receptor occupancy potentiates intracellular free calcium to rise. Some evidence for this hypothesis is presented as is mention of the development of environmental toxicological and low frequency AC magnetic field tests based on diatom sensory biology. The project allowed nine publications.... Diatom, Calcium, Fouling, Signal-transduction, Model, Biofilm
