Fig 2. Correlation analysis between liposoluble pigment absorbance and S. pinnata growth at HLmix conditions.

a) UV-vis absorbance spectrum of culture liposoluble extract obtained at the exponential phase; b) Non-linear polynomial fitting of absorbance values recorded at 435 nm over growth time; c) Linear regression between 435 nm absorbance values and Log cell numbers at days 0, 2, 4 and 7. Bars represent SD between culture replicates.
