Résumé

Four strains of Bifidobacterium longum were grown at pH 5.5, 6.0, 6.5 and 7.0 and evaluated for survival and bile tolerance during frozen and subsequent refrigerated storage in milk. There were no reductions in all numbers following initial freezing. There were effects for strain, pH and storage for three of the four strains of B. longum during storage at 5 °C in milk. Bifidobacterium longum S9 was more stable than other strains in that no losses occurred. Results were variable for strains II, III, and ATCC 15707. Bifidobacterium longum S9 did not lose bile resistance during refrigerated storage as the other three strains did.
