Tuning oxygen limitation for polyhydroxyalkanoate production from alkaline lignin liquor fermentation and comparison with nitrogen limitation

Figure 3. Peak PHA production and its corresponding cell growth of P. putida within 72 h on acetate, vanillic acid, ferulic acid as the sole carbon source, and their mixture at 6.67 mM each under O₂-limited conditions. Error bars represent the standard deviation of two replicates (n = 2). PHA: Polyhydroxyalkanoates; P. putida: Pseudomonas putida.
