A whole‐cell hypersensitive biosensor for beta‐lactams based on the AmpR‐AmpC regulatory circuit from the Antarctic Pseudomonas sp. IB20

Microbial Biotechnology
Detecting antibiotic residues is vital to minimize their impact. Yet, existing methods are complex and costly. Biosensors offer an alternative. While many biosensors detect various antibiotics, specific ones for beta‐lactams are lacking.
