The accumulation of antibiotics in the environment due to disposal of waste or antibiotic use in agriculture is one of the reasons for the generation of antibiotic resistance. Some bacteria develop mechanisms to withstand the onslaught, some even use the antibiotic as substrate. This fact was a shock some years ago, but now, some researchers want to benefit from this situation deploying bacteria as exterminator of antibiotics which are contaminating the environment. As normal soil bacteria, which naturally eat antibiotics, are too tricky to handle, the researchers want to engineer E. coli bacteria so that they “get appetite for specific antibiotics”.
