The probes used in the study were Bif164 and Lab158, specific
for bifidobacteria and lactobacilli, respectively. These were commercially

(GeneWorks, Australia). The procedure described by Dinoto et al.
(2006) was followed with some modifications. In short, FBCF mixtures
were centrifuged at low speed (700 g) to remove debris
