摘要:
Paenibacterin is a novel antimicrobial lipopeptide produced by Paenibacillus thiaminolyticus. The present study assesses the efficacy of paenibacterin in inhibiting Listeria monocytogenes biofilm formation and removing established biofilm. Paenibacterin at 1.7 mu g/mL (less than compound's minimum inhibitory concentration, MIC) and higher concentrations (3.4 mu g/mL, 6.8 mu g/mL) were tested. Concentrations greater than the lipopeptide's MIC significantly inhibited the formation of L. monocytogenes biofilm on polystyrene microtiter plates at 30 degrees C and 37 degrees C. Paenibacterin also wa...
