Effect of H₂O₂ Supplementation on TAG and Starch Content during Photoautotrophic Growth.

(A) Cell growth.

(B) Starch content per cell.

(C) TAG content per cell.

Cells were cultivated under constant light in photoautotrophic conditions with additional supply of 2% CO₂ in the air. Cells were collected before and 2 d after H₂O₂ addition (0.5 mM). A given number of cells was deposited on MM agar plates with or without addition of H₂O₂. Images were taken 7 d after cells being deposited. Values are the mean of biological replicates (i.e., independent shaking flask cultures; n = 4, sd). Asterisks indicate statistically significant difference from control strains (dw15 and C1) by paired-sample Student’s t test (**P ≤ 0.01).
