Selected propionic acid bacteria culture.

The culture is primarily used for the production of Swiss-type cheeses, such as Emmental, Gruyère, Greve and similar types where the typical propionic acid aroma and eye formation are desired.

The culture is normally applied in combination with lactic cultures, such as Streptococcus thermophilus , Lactobacillus helveticus, Lactobacillus delbrueckii subsp.bulgaricus and LD cultures.

The culture ferments lactate resulting in the formation of propionic and acetic acids and large amounts of carbon dioxide.

Propionic acid cultures grow slowly in milk and have a low proteolytic activity.
