Yearly approvals of biotechnology-deriv drugs and vaccines.

Yearly average areal productivity of an inclined flat-panel PBR . Values are given for the microalga C. vulgaris and for the cyanobacteria A. platensis, illustrating the narrower range of residence time to maximize productivity for eukaryotic cells as explained by their sensitivity to dark volumes induced by too high values of residence time values.
