Effects of wzt deficiency on growth and FFA production. WT, dAS1T, and dAS1T∆wzt cells grown under low light (50 μE m⁻² s⁻¹) in nitrate-containing medium were inoculated at time zero into new nitrate-containing medium and incubated under the high-light conditions (180 μE m⁻² s⁻¹). A Cell density measured at designated times (a) and appearance of the cultures at t = 240 h (b). B Changes in extracellular FFA concentration (a), cellular FFA content (b), and the sum of cellular and extracellular FFA in the cultures (c). Black circles WT; blue circles dAS1T; green circles dAS1T∆wzt. Data shown are the mean ± SE from biological triplicates
