a Schematic metabolic network of glucose generation in PCC 7942. Cell growth (b) and glucose production (c) of SZ3, SZ130 (SZ3-ΔinvA), and SZ131 (SZ3-Δsps). d Glucose production of SZ17 and SZ159 (SZ17-Δsps). Cultivation was conducted at 30 °C, 200 µmol photons/m2/s, and bubbled with 3% CO2. Data are presented as mean values ± SD (n = 3 biological replicates).
