E. coli that is recoded to be virus resistant may aid drug production

Changing Escherichia coli‘s genetic code may enable the recoded bacterium to be grown in large vats for drug production, without the risk of a viral infection upending the process

Some viruses can infect and kill a recoded Escherichia coli bacterium that was supposedly resistant to all viral infections, but further changes have made the bacterium much more virus-resistant.

Many chemicals and drugs, such as insulin, are produced by growing genetically engineered E. coli in large vats, but bacteria-infecting viruses called bacteriophages can wreak havoc. “If a single bacteriophage gets into these …
