Low-temperature fermentation is the old-world move for salami when the goal isn’t a sharp “tang,” but a slow, elegant build of aroma. Instead of pushing warm temps to drive fast acidification, producers often ferment cool—think cellar conditions—so the starter culture works gradually while the real magic happens in the background. The result is a salami that tastes cured rather than sour—clean pork character, deeper spice expression, and a more traditional European bite.

Chr. Hansen’s product sheet lists these organisms:

• Debaryomyces hansenii (yeast)
  
• Lactobacillus sakei (lactic acid bacteria, LAB)
  
• Pediococcus acidilactici (LAB)
  
• Pediococcus pentosaceus (LAB)
  
• Staphylococcus carnosus (coagulase-negative staph)
  
• Staphylococcus xylosus (coagulase-negative staph)

Pediococcus acidilactici: A fast acidifier that’s especially valued for strong anti-Listeria activity via pediocin-type bacteriocins and competitive dominance.

Lactobacillus sakei: A hardy “workhorse” LAB that drives reliable fermentation and pH drop and can contribute additional anti-Listeria pressure (strain-dependent bacteriocins).

Pediococcus pentosaceus: A clean, predictable LAB that supports rapid, consistent acidification for safety, texture set, and batch-to-batch repeatability.

Staphylococcus carnosus: A curing “utility player” that improves color stability (nitrate/nitrite chemistry support) and flavor protection through catalase and related enzymatic activity.

Staphylococcus xylosus: A flavor-builder that helps develop classic fermented-sausage aroma while supporting color development and oxidation control during ripening.

Debaryomyces hansenii: A surface-friendly yeast that boosts savory cured aromatics and helps “round out” the profile by transforming fats/proteins into appealing flavor notes.
