Behavior of Listeria monocytogenes in the Presence of Lactic Acid Bacteria in an Agitated Medium with Internal pH Control.

An agitated medium with internal pH control (IPCM-2) was inoculated to contain Listeria monocytogenes (strain V7, Scott A or California) at ca. 10 CFU/ml and Streptococcus cremoris (Lactococcus lactis subsp. cremoris) or Streptococcus lactis (Lactococcus lactis subsp.

Behavior of Listeria monocytogenes in the Presence of Streptococcus lactis in a Medium with Internal pH Control.

Growth of Listeria monocytogenes strains V7, Scott A, and California (initial inoculum 10/ml) at 21 or 30°C in the presence of Streptococcus Iactis (initial inoculum 0.25 or 1.0%) was determined using a medium with internal pH control (IPCM-1).
