Characteristics of some lactic Acid bacteria used as starter cultures in dry sausage production

The fermentation characteristics of two commercial (Duploferment 66 and Saga II) and five Norwegian lactic acid bacteria used in dry sausage production were compared with those of Lactobacillus plantarum ATCC 8014. The Norwegian strains lacked the ability to ferment mannitol, sorbitol, lactose, and d-(+)-raffinose and grew at 8 but not at 42 degrees C, in contrast to the ATCC culture and the two commercial strains. The lactate dehydrogenase activity of the Norwegian strains was not stimulated by pyruvate. All strains were capable of peroxide destruction when grown in the presence of myoglobin.
