To determine whether fermented rice extract (FRe) has bifidogenic growth-stimulating effects in vitro, the effects of FRe on the growth of lactic acid bacteria and bifidobacteria were evaluated. Treatment with 0.2% FRe stimulated the growth of three strains of lactic acid bacteria (Lactobacillus acidophilus, Streptococcus thermophilus, and Bifidobacterium lactis), significantly increasing the number of cells by 11 – 53 fold after 12 – 18-h incubation compared with the control (p < 0.05). HPLC analysis indicated that the panose content of the FRe powder was 6.7%. The growth-stimulating effects of FRe on bifidobacteria and lactic acid bacteria were likely due to panose, and additional unknown and/or known substances in the FRe. Based on these results, we propose that FRe could be used as a growth stimulator for bifidogenic and lactic acid bacteria in pharmaceutical and food applications.
