Figure 6. Photoinactivation of V. fischeri with Tri-Py⁺-Me-PF at 10, 20 and 50 µM, in an aquaculture water sample collected in May 2010, under 4 mW cm⁻² irradiation.

A: non-filtered portion; B: portion filtered by 0.7 µm membrane; C: portion filtered by 0.2 µm membrane. Values represent the mean of two replicates of the same sample; error bars indicate the standard deviation.
