As this study tends to explore operation strategy for materials recycling during dye-containing wastewater treatment, dye-decolorizer Aeromonas hydroiphila NIU01 which also owned significant tolerant capabilities to dyes and decolorized intermediates was used for study, but not popularly-used PHB-producing bacteria (e.g., Ralstonia eutropha)[11]. This feasibility study showed that separation cell growth phase from PHA production phase of A. hydrophila NIU01 using two-stage fermentation strategy to maximize PHA production was technically viable.
