Mode of action of linenscin OC2 against Listeria innocua.
Linenscin OC2 is a small hydrophobic substance produced by the orange cheese coryneform bacterium Brevibacterium linens OC2. Linenscin OC2 inhibits growth of gram-negative bacteria with an altered outer membrane permeability and gram-positive bacteria. It is also able to lyse eucaryotic cells. The mode of action of linenscin OC2 on the Listeria innocua cytoplasmic membrane and the effects of en...
متن کاملRecovery of heat-injured Listeria innocua.
Listeria innocua was subjected to thermal inactivation and the extent of heat-injured cells was quantified. Cultures were heated in liquid medium for different times, using temperatures in the range of 52.5 to 65.0 degrees C, and plated on Tryptic Soy Agar with 0.6% yeast extract (TSAYE) used as non-selective medium and on TSAYE plus 5% NaCl (TSAYE+NaCl) and Palcam agar with selective supplemen...
متن کاملFatal case of Listeria innocua bacteremia.
Listeria innocua is widespread in the environment and in food. This species has to date never been described in association with human disease. We report a case of fatal bacteremia caused by L. innocua in a 62-year-old patient.
متن کاملThe species-specific mode of action of the antimicrobial peptide subtilosin against Listeria monocytogenes Scott A.
AIMS To elucidate the molecular mechanism of action of the antimicrobial peptide subtilosin against the foodborne pathogen Listeria monocytogenes Scott A. METHODS AND RESULTS Subtilosin was purified from a culture of Bacillus amyloliquefaciens. The minimal inhibitory concentration of subtilosin against L. monocytogenes Scott A was determined by broth microdilution method. The effect of subtil...
متن کاملAerosol studies with Listeria innocua and Listeria monocytogenes.
Aerosol studies of Listeria monocytogenes in food processing plants have been limited by lack of a suitable surrogate microorganism. The objective of this study was to investigate the potential of using green fluorescent protein-labeled strains of Listeria innocua as a surrogate for L. monocytogenes for aerosol studies. These studies were conducted in a laboratory bioaerosol chamber and a pilot...
