Fig. 5From: Expression and secretion of a lytic polysaccharide monooxygenase by a fast-growing cyanobacteriumBiomass and pigment accumulation of Synechococcus elongatus UTEX 2973 over 96 h. S. elongatus UTEX 2973 transformants were grown in modified P4-TES CPH medium at 38 °C and bubbled with 3% CO2 supplemented air. The cultures were illuminated with a linear light gradient from 250 µmol photons m−2 s−1 to 900 µmol photons m−2 s−1 over 12 h, followed by continuous illumination with 900 µmol photons m−2 s−1. Cell number (a), optical density (750 nm) (b), carotenoid (c) and chlorophyll content (d) were determined. Carotenoid and chlorophyll concentrations are normalized to 1 × 106 cells. Error bars represent the standard deviation (n = 3)Back to article page
