Effect of different fermentation conditions on cell growth, glucose consumption, spinosad and PSA production of wild-type S. spinosa , and cell growth spinosad and PAS production of rex -mutant Lu106. (A) Fermentation curve of rex-mutant Lu106 under control condition (star) and fermentation curve of wild-type under control condition (square), oxidative condition- H₂O₂ (circle), and reductive condition- DTT (triangle); (B) Glucose consumption of wild-type under control condition (square), oxidative condition- H₂O₂ (circle), and reductive condition- DTT (triangle); (C) Spinosad and PSA production of rex-mutant Lu106 under control condition and spinosad and PSA production of wild-type under control condition (control), oxidative condition- H₂O₂, and reductive condition- DTT.
