Fig. 1. T. pseudonana vitamin B12 bioassay.

Fig. 1

Shown is the growth of T. pseudonana at varying B12 concentrations, monitored by relative fluorescence (A, B) and cell count (C, D). In A the Y-axis represents the relative fluorescence and in C the Y-axis represents diatom cell count/ml. Depicted are maximum growth determined by relative fluorescence (B) and cell count (D) of the diatom at respective B12 concentrations.
