The effect of ultraviolet light (UV-C) on marine phytoplankton fluorescence / by R. B. Martin, D. D. R. Markus, and T. F. Sutherland. : Fs97-6/3289E-PDF
"The effect of ultraviolet radiation (UV-C) on the photosynthetic activity of a natural marine phytoplankton community was measured through fluorescence outputs. Phytoplankton samples, with and without UV-C treatment, were incubated in both light and dark conditions to mimic oceanic and ballast-tank settings. The control phytoplankton samples that were not exposed to UV-C light showed traditional growth and mortality curves associated with light and dark incubation conditions, respectively. Treated phytoplankton samples showed a sharp decrease (-63%) in fluorescence values within minutes of being exposed to UV-C light. A notable increase in fluorescence during the early stages of the dark incubation, relative to that of light incubation, suggests that some form of dark DNA repair may have taken place. Alternately, the fluorescence outputs under light incubation conditions remained relatively stable after treatment and initial decrease in fluorescent values. Phytoplankton incubation experiments should be carried out for long periods of time in order to test phytoplankton survivability and regrowth potential"--Abstract.
