Biodegradation of β-lactam antibiotic 'ampicillin' by white rot fungi from aqueous solutions

The worldwide higher usage and release of Pharmaceutical and Personal Care Products (PPCPs) into is an emerging environmental issue as it has adverse effects to humans, animals, plants and microorganisms. Hence it is necessary to find a novel mechanism to degrade and remove these PPCPs from the polluted site. One of the possible methods is employing white rot fungi, as it has the capability of degrading lignin. In this study, use of white rot fungi Verticillium leptobactrum KCTC 26026 to degrade a ß-Iactam antibiotic ampicillin was investigated. The antibiotic was added at a concentration of 0.5 mg L^-1,1.0 mg L^-1 and 2.0 mg L^-1 and incubated for 7 days in a laboratory simulated environment. The HPLC-DAD studies have shown 100% depletion of ampicillin. To the best of our knowledge, this is the first study in which white rot fungi Verticillium leptobactrum KCTC 26026 was employed for degrading antibiotic.
