Quantifying the significance of phage attack on starter cultures: A mechanistic model for population dynamics of phage and their hosts isolated from fermenting sauerkraut

Article Abstract:

The possibility of using starter cultures in sauerkraut fermentation was investigated, thereby reducing the quantity of salt used in the process, which in turn would reduce the amount of waste salt that would enter in the water resources. Phage, naturally present in sauerkraut fermentation, could potentially affect the starter cultures introduced and therefore a mechanistic mathematical model was developed to quantify the growth kinetics of the phage and starter cultures.

Resistance of Listeria monocytogenes biofilms to sanitizing agents in a simulated food processing environment

Article Abstract:

The resistance of biofilms of Listeria monocytogenes to sanitizing agents under laboratory conditions simulating a food processing environment is evaluated. The results have indicated that the resistance of the treated biofilms to sanitizing agents might be due to the attributes of extracellular polymeric substances and is not an intrinsic attribute of the cells in the biofilm.

Enumeration of viable Listeria monocytogenes cells by real-time PCR with propidium monoazide and ethidium monoazide in the presence of dead cells

Article Abstract:

Propidium monoazide (PMA) and ethidium monoazide are used for enumeration of viable Listeria monocytogenes cells in the presence of dead cells. PMA does not have any antimicrobial effect on Listeria monocytogenes and viable cell counts are related to real-time PCR threshold cycle values for PMA-treated cells from plaktonic and biofilm sources.
