Abstract:

Feruloylated oligosaccharides (FOs) are derivatives of the esterification products of ferulic acid. The product of FOs (GRAS Notice 000343) approved by the Division of Biotechnology and GRAS Notice Review, United States Food and Drug Administration (FDA) in 2010. It possesses the physiological functions of antioxidant activity, probiotic effects and inhibition against glycation. The effects of feruloylated oligosaccharides (FOs) from maize bran on the microbial diversity and profiles in rat feces were investigated through 16S rRNA sequencing. The effects of FOs on chemical parameters in the plasma, liver, and heart were also evaluated. FOs significantly increased bacterial richness and diversity compared with the control and xylooligosaccharides (Xyl) alone. Compared with the control and Xyl, FOs orally administered at 300 mg/kg increased OUT (operational taxonomic units) by 57.0% and 24.8%, and CHAO value by 93.4% and 37.6%, respectively. FOs also influenced obesity- and diabetes-associated bacteria. FOs orally administered at 300 mg/kg decreased the ratio of Firmicutes to Bacteroidetes from 477.7 to 40.7; greatly increased the reads of bacteria that were previously found resistant against diabetes in rats, such as Porphyromonadaceae, Prevotellaceae, and Lachnospiraceae; and moderately increased diabetes-prone bacteria, such as Clostridiaceae and Ruminococcaceae. FOs administration at 300 mg/kg also significantly decreased serum triglyceride and low-density lipoprotein cholesterol but did not significantly influence glucose, total cholesterol, and high-density lipoprotein cholesterol in serum, and thiobarbituric acid-reactive substances and glutathione in the plasma and liver. FOs decreased nitric oxide (NO) content in the heart but increased it in the plasma and liver.
