Zusammenfassung:Azospirillum lipoferum is a soil microorganism that has been shown to be resistant to penicillins. It has been suggested that resistance is due to the presence of a beta -lactamase activity, but no conclusive evidence has been reported. The enzyme was produced at a low, basal level that was increased approximately 50 times by the addition of benzylpenicillin, an increase that was completely blocked by chloramphenicol or rifampicin.
