Growth activity of four Bifidobacterium species (B. adolescentis, B. catenulatum, B. pseudocatenulatum and B. bifidum). Each of the six bifidogenic growth factors was added at half the concentration in GAM broth and bacteria were cultivated in anaerobic conditions. Significant differences were determined by the Student t-test (*P < 0.05, P < 0.1). Error bars show the standard deviations of the mean.
