Growth Behavior and Fatty Acid Production of Probiotics, Pediococcus acidilactici and Lactococcus lactis, at Different Concentrations of Fructooligosaccharide: Studies Validating Clinical Efficacy of Selected Synbiotics on Growth Performance of Caspian Roach (Rutilus frisii kutum) Fry.

Growth behavior and production of short-chain fatty acid (SCFA) of two probiotics, Pediococcus acidilactici and Lactococcus lactis, each at 10 cfu/g (P1, L1) and 10 cfu/g (P2, L2) at different concentrations of fructooligosaccharide (FOS) [0.5% (F1), 1% (F2), and 2% (F3)] were assessed in vitro. The time to reach the maximum growth of the probiotics in all 12 treatments was between 8 to 10 h, with the highest and the lowest growth rates obtained in F1L1P1 (0.
