Transmittance and light penetration in photobioreactors. Transmittance (a) and irradiances (b) at different layer of photobioreactors were calculated considering the absorption spectra of whole cells, the incident light intensity (400 µmol photons m−2s−1) and the concentration of chlorophyll at exponential phase in photobioreactors. Error bars are reported as standard deviation (n = 3)
