Current Research Interests

Antibiotic resistance is one of the ten most important threats to global health according to WHO. Animal agriculture is a crucial sector using antibiotics. Animal manure is a common substrate for large-scale anaerobic digestion (AD) systems. Depending on the medical treatment of animals the manure is often contaminated with antibiotics and antibiotic resistant genes (ARGs).

It was pointed out that AD systems can be potential reservoirs for multi-resistant bacteria considering the continuous load of antibiotics and various resistant bacteria from livestock manure. On the contrary, we believe that the survival of resistant bacteria from livestock can be reduced in a well-managed AD process. We hypothesize that the management of operational parameters and the application of various post-treatments can enhance the degradation of antibiotics and effectively reduce the abundance of ARGs.
