摘要： Bananas are rich in indigestible carbohydrates and are considered potential whole-fruit prebiotics. To investigate banana-induced changes in the composition of the human gut microbiota and the production of short chain fatty acids (SCFAs), ripe banana (Musa acuminataColla, Degrees Brix: 22.6 +/- 0.2 degrees Be), from Hainan, China, was powdered and fermentedin vitrofor 24 hr with the feces of six Chinese donors. The degradation of banana polysaccharides was observed in all six fecal samples. Duringin vitrofecal fermentation, banana polysaccharides were gradually degraded up to approximately 80%. The production of SCFAs was also measured. The addition of banana powder increased the concentrations of acetate, propionate, and butyrate, with the production of acetate being higher than that of propionate and butyrate. Changes in the human gut microbiota were assessed using high-throughput sequencing of the 16S ribosomal RNA (rRNA) gene. The results indicated that banana powder significantly altered bacterial diversity, increasing the relative abundance ofBacteroides, while maintaining the proportion ofBifidobacteriumin the feces. At the same time, banana powder also increased the proportion ofLactobacillus; however, a significant difference was not observed. In summary, banana powder can be utilized by specific bacteria in human intestines, providing data support for the study of the effects of banana powder on the human intestinal health. Practical Application In this study,in vitrobatch fermentation was used to evaluate the effect of banana powder on the human intestinal microbial community, and the metabolized products of banana powder were determined. Our study showed that banana powder improved the human intestinal microbial flora and promoted the growth ofBifidobacteriumandBacteroidesand could produce beneficial SCFAs (acetate, propionate, and butyrate). This study provided a theoretical basis for the use of banana powder as a potential prebiotic in production applications and our daily diet.
