The mixed microbial culture was found to remove more than 90% of the initial PVA concentrations, within the range of 3.13 to 6.64 g l-1 in 16–25 days of incubation at 35 °C.
📌 3 Key Takeaways
🎯
Objective & Hypothesis:Mixed microbial culture from paper mill treatment system was enriched on polyvinyl alcohol (PVA) medium and its PVA biodegradation capacity was investigated as a function of change in the initial pH values and PVA concentrations.
📊
Key Findings & Data:The optimum pH value at 0.75 g l-1 initial PVA concentration was determined to be 8.
💡
Conclusion & Impact:The mixed microbial culture was found to remove more than 90% of the initial PVA concentrations, within the range of 3.13 to 6.64 g l-1 in 16–25 days of incubation at 35 °C.
Mixed microbial culture from paper mill treatment system was enriched on polyvinyl alcohol (PVA) medium and its PVA biodegradation capacity was investigated as a function of change in the initial pH values and PVA concentrations. The optimum pH value at 0.75 g l-1 initial PVA concentration was determined to be 8. PVA biodegradation by mixed microbial culture was investigated at the range of 0.68 – 15.5 g l-1 initial PVA concentrations. The mixed microbial culture was found to degrade within 5 days 98.6–88.5% of the initial PVA levels which ranged from 0.68 to 1.14 g l−1. The mixed microbial culture was found to remove more than 90% of the initial PVA concentrations, within the range of 3.13 to 6.64 g l-1 in 16–25 days of incubation at 35 °C.
