Irradiation Sensitivity of Planktonic and Biofilm-associated Listeria monocytogenes and L. innocua as Influenced by Temperature of Biofilm Formation
The human pathogen Listeria monocytogenes forms biofilms that are relatively resistant to chemical sanitizing treatments. Ionizing radiation effectively inactivates planktonic Listeria, but no information is available on the relative efficacy of the process against biofilm-associated Listeria. The irradiation sensitivity of planktonic or biofilm cells was determined for L. monocytogenes ATCC 43...
متن کاملDevelopment and characterization of a monoclonal antibody specific for Listeria monocytogenes and Listeria innocua.
BALB/c mice were immunized with crude cell surface proteins of Listeria monocytogenes V7. Approximately 1,680 hybridomas were generated after two fusions, and the monoclone C11E9 was selected and used for further characterization. The monoclonal antibody (MAb) produced by C11E9 was immunoglobulin subclass G2b with kappa light chains. Dot and colony blot results indicated that MAb C11E9 was reac...
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...
متن کامل1,2-β-Oligoglucan Phosphorylase from Listeria innocua
We characterized recombinant Lin1839 protein (Lin1839r) belonging to glycoside hydrolase family 94 from Listeria innocua. Lin1839r catalyzed the synthesis of a series of 1,2-β-oligoglucans (Sopn: n denotes degree of polymerization) using sophorose (Sop2) as the acceptor and α-D-glucose 1-phosphate (Glc1P) as the donor. Lin1839r recognized glucose as a very weak acceptor substrate to form polyme...
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...
