Figure 6: Algae concentration as a function of time.
From: Solar spectral conversion for improving the photosynthetic activity in algae reactors
Data represent identical reactor set-ups with (red curve) and without Sr0.40Ca0.59Eu0.01S spectral converter (green curve). The inset exemplarily shows photographs of the employed algae species H. pluvialis in its active and transition state. Data were obtained at room temperature in an Opticell minireactor. The yellow part of the diagram refers to the incubation time. Scale bar, 100 μm. The error bars indicate a counting error of 25,000 cells per ml.
