Biodegradation of p-nitrophenol in anaerobic fixed film fixed bed reactor.
Biodegradation of p-nitrophenol (PNP) was studied in upflow anaerobic fixed film fixed bed reactor. The studies showed that PNP was not degraded as a sole carbon source in the reactor. Addition of glucose as co-substrate increased the degradation of PNP. A ratio of > 1 in terms of glucose to PNP could achieve 90% PNP degradation. However the total organic carbon (TOC) removals were 76.3% indicating the possibility of biotransformation of PNP.
