Description générale
No detectable growth in tryptone soy broth at 30-35 °C for 14 days
Actions biochimiques/physiologiques
β-Lactamases exhibit high carbapenemase activity. β-lactamases can destroy the β-lactam ring. True carbapenemases has the ability to hydrolyse several β-lactam ring containing carbapenems like meropenem, doripenem, imipenem and ertapenem.
