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 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.
