A considerable variation is noticed between the different species studied and even between the strains of the same species, in the assimilation of cholesterol in synthetic media, in presence of different concentrations of bile salts and under anaerobiosis conditions. The obtained results show that certain strains of Streptococcus thermophilus and Lactobacillus bulgaricus resist bile salts and assimilate appreciable cholesterol quantities in their presence. The study of associations shows that only strains assimilating cholesterol in a pure state remain active when they are put in associations, but there is no additional effect. However, the symbiotic effect between Streptococcus thermophilus and Lactobacillus bulgaricus of yogurt, with regard to bile salts, is confirmed. The lactic fermenters of yogurt (Y2) reduce the levels of total cholesterol, HDL-cholesterol and LDL-cholesterol, in a well-balanced way. In all cases, the assimilated quantity of HDL-cholesterol is lower than that of LDL-cholesterol. Moreover, yogurt Y2 keeps a significant number of bacteria, superior to 108 cells ml-1, and has a good taste 10 days after its production.
