Biodegradation of norfloxacin by <i>Penicillium frequentans</i> isolated from polluted soil

Abstract

One norfloxacin-degrading fungi was isolated from soil contaminated by norfloxacin and preliminary identified as Penicillium frequentans. Indoor simulative degradation experiments were carried out to investigate the biodegradation kinetics of norfloxacin with or without NFX3 in soil. The results indicate that the biodegradation of norfloxacin were both in accordance with first-order kinetics equation whether the NFX3 existed or not, and the microbial degradation rate constant of norfloxacin with NFX3 in soil was 0.0121 day^-1.

Keywords: Norfloxacin, soil, biodegradation, microbial consortium.
