摘要:

探究復(fù)合蔬菜酵素對健康青年腸道菌群的影響規(guī)律，為酵素產(chǎn)品的飲用作指導(dǎo)。26例無外源性抗生素和糞便微生物群移植的健康青年持續(xù)14 d飲用復(fù)合蔬菜酵素，在第0，7 d和14 d分別采取糞便樣品，采用高通量測序檢測各組糞便樣品中的菌群。結(jié)果表明，健康青年持續(xù)攝入復(fù)合蔬菜酵素時(shí)，腸道菌群的結(jié)構(gòu)和豐度發(fā)生變化。在門和屬分類學(xué)水平上，健康青年腸道菌群的結(jié)構(gòu)和豐度在0，7 d和14 d相比，均具有較大的差異；第14 d時(shí)逐漸恢復(fù)到第0 d的菌群豐度和結(jié)構(gòu)。通過分析PICRUSt2和KEGG數(shù)據(jù)庫，發(fā)現(xiàn)與菌群豐度和結(jié)構(gòu)對應(yīng)的功能結(jié)構(gòu)有類似的變化規(guī)律。本研究結(jié)果對明確酵素對人體腸道菌群的影響提供了理論參考。

Abstract:

This paper aimed to investigate the effects of the vegetable jiaosu complex on the intestinal flora of healthy youths and provide guidance for the consumption of jiaosu products. 26 healthy youths without exogenous antibiotics or fecal microbiota transplants consumed the vegetable Jiaosu complex for 14 days. Fecal samples were taken at days 0， 7， and 14， and the flora in each group was measured by high-throughput sequencing. The results showed that the structure and abundance of intestinal flora changed in healthy youths with continuous intake of the vegetable jiaosu complex. At the phylum and genus taxonomic levels， the structure and abundance of the intestinal flora of healthy youths were significantly different at days 0， 7， and 14 compared to each other； the abundance and structure of the flora gradually returned to that of day 0 at day 14. The PICRUSt2 and KEGG databases were analyzed， and similar patterns of change were found in the functional structures corresponding to the abundance and structure of the flora. The results of this study provide a theoretical reference to clarify the effect of enzymes on human intestinal flora.
