Inducible class C beta-lactamases produced by psychrophilic bacteria

Only class C beta-lactamases were found to be synthesised by ampicillin-resistant psychrophilic bacteria collected in the Antarctic. Most of them were inducible but the induction factor varied greatly. Even in non-induced conditions, where no lysis occurred, a large proportion of the activity was fo...

Description
Summary:Only class C beta-lactamases were found to be synthesised by ampicillin-resistant psychrophilic bacteria collected in the Antarctic. Most of them were inducible but the induction factor varied greatly. Even in non-induced conditions, where no lysis occurred, a large proportion of the activity was found in the culture supernatant, an unusual observation with class C producers.
