LISTEX™ P100

LISTEX™ P100 is a culture of safe micro-organisms (bacteriophage preparation) in use as a processing-aid, characterized by its broad spectrum toward Listeria monocytogenes strains.

The use of LISTEX™ P100, and its application, can be easily integrated within the daily routine of the normal production process. The application of LISTEX™ P100 does not affect any of the properties of the food product, be it chemical, physical, or organoleptic (i.e. taste and flavor).

LISTEX™ P100 (Activity, Survival & Inactivation)

Activity

• Temperature: optimum 30°C, range 1 to 35°C.
• pH: optimum 7.7 , range 5.5 – 9.5
• Water activity: minimum aw permitting activity = 0.92. Optimum at 0.99.
• NaCl: high tolerances up to saturated solutions.

Survival

• Temperature: optimum 4°C. Range 0+°C to 37°C. Stable at 42°C. for at least 48 hours.
• pH: optimum 7.5, will retain stability at pH 3 for 4 hours.
• Atmosphere: not influenced by atmosphere.
• NaCl: will survive in saturated solutions

Inactivation

• Temperature: rapidly inactivated at temperatures above 50°C.
• pH: inactivated at pH values less than 3. Inactivation proceeds faster at higher temperatures.
• Water activity (aw): can remain viable in dry environments (next to 0) for long periods.
• Salt (NaCl): rapid desalination can cause osmosis and inactivate phage. Allow 2 minute intervals for every 10% salt reduction in solutions
• Hypochlorine (HoCl): avoid contact. Rapid inactivation at low levels
