Bacillus subtilis CL27 and B. pumilus CL45 showed similar activity against Botrytis cinerea in in vitro plate assays. In a seedling bioassay, however, B. subtilis CL27 had activity similar to a commercial fungicide while B. pumilus CL45 failed completely to prevent seedling damping-off caused by Bot. cinerea. Antibiotic production by the two Bacillus(More)
AIMS The aim of this research was to investigate the potential of Lactobacillus plantarum strain SK1 for use as a biological control agent against Listeria monocytogenes and determine its mechanism of anti-listerial activity. METHODS AND RESULTS Co-growth of Lact. plantarum SK1 and L. monocytogenes UMCC98 in MRS broth showed that anti-listerial activity(More)
We describe here the identification and characterization of two Listeria monocytogenes (Tn917-LTV3) relA and hpt transposon insertion mutants that were impaired in growth after attachment to a model surface. Both mutants were unable to accumulate (p)ppGpp in response to amino acid starvation, whereas the wild-type strain accumulated (p)ppGpp within 30 min(More)
