Restriction fragment differential display of pediocin-resistant Listeria monocytogenes 412 mutants shows consistent overexpression of a putative beta-glucoside-specific PTS system.

Abstract excerpt

Pediocin PA-1, which is a bacteriocin produced by lactic acid bacteria, has potential as a biopreservative of food. However, such use may lead to the development of resistance in the target organism. Gene expression in two independent pediocin-resistant mutants of Listeria monocytogenes 412 was compared to the original isolate by restriction fragment differential display PCR (RFDD-PCR). This method amplifies cDNA...
