For lactobacilli this effect was ascribed to the release in themilk of additional nutrients like aminoacids or the reduction of a negative environmental impact. In particular, the mean doubling time of the two probiotic strains testedwere remarkably
and significantly lower in co-cultures (SYNBIO®) in the presence of both buckwheat flour and oat bran, confirming the occurrence of a synergism between the two strains (Cresci et al., 2005; Verdenelli et al., 2009, 2011). As demonstrated by Oliveira et al. (2011) even the supplementation of inulin in fermented skin milk lowered the generation time more
prominently in co-cultures, showing the occurrence of a synergism between the probiotic strains tested. The stability of L. rhamnosus IMC 501®, L. paracasei IMC 502® and SYNBIO® during storage at 4 °C for 28 days in buckwheat flour- and oat bran-supplemented milks was remarkably
improved.
