FIGURE 5.

Viability, cell growth and photosynthetic activity of suspension cultures (A–C) and 3D bioprinted cultures (D–F) of Scenedesmus sp. cultivated over 7 days under red illumination (150 µmol/m²s) at 37°C in TP medium without and with antibiotics (P/S: 100 U/ml penicillin and 100 μg/ml streptomycin; 100 U/ml penicillin; 100 μg/ml ampicillin). The cell numbers (B,E) were normalized to the cell number measured on day one for the respective group. Depicted are mean ± standard deviation, n = 6¸ *p < 0.05; **p < 0.01¸ ***p < 0.001.
