Growth and levels of chlorophyll a contents from engineered cyanobacteria. a Growth inhibition of the recombinant strains with an OverMEP module, but a TPS. Cyanobacterial cells were cultivated for 7 days with 5 % CO₂ bubbling. Growth of the strains producing amorphadiene (SeHL33A; black square), squalene-producing strain (SeSC33S; red circle), and an OverMEP strain lacking a TPS (SeHL33; blue triangle) was measured at OD₇₃₀. All data are the mean ± standard deviation (SD) from the triplicated cultures. b Levels of Chlorophyll a contents (mg/L/OD₇₃₀) from engineered cyanobacteria. Chl a contents were measured by a spectrophotometric assay from cyanobacterial cells cultivated for 2 and 8 days. Strains are presented as WT (black bar), SeHL33A (gray bar), SeSC33S (blue bar), and SeHL33 (green bar). All data are the mean ± standard deviation (SD) from the triplicated cultures
