Objectives: Non-alcoholic fatty liver disease (NAFLD) is a prevalent chronic disorder of the liver and affects many people worldwide. Intestinal bacteria are thought to be involved in the pathological progression of NAFLD; therefore, improving the intestinal microbiota may be important in controlling NAFLD. In this study, we assessed the effects of water-soluble cellulose acetate (WSCA) on the intestinal microbiota in a non-alcoholic steatohepatitis (NASH) mouse model. Methods: NASH model (STAM mice) was created by streptozotocin injection and feeding the mice a high-fat diet. The serum biochemical parameters were analyzed. Intestinal bacterial populations were analyzed using paired-end sequencing of 16S rRNA, 18S rRNA, and internal transcribed spacer gene. Results: Our findings indicated that WSCA administration tends to improve the serum alanine aminotransferase and glucose levels in STAM mice and decreased the alpha diversity and altered the beta diversity of their intestinal microbiota. Additionally, WSCA intake resulted in an increase in the abundance of Coriobacteriaceae_UCG-002 and a decrease in the abundance of Enterobacter. Conclusions: WSCA intake can alter specific microbial compositions to improve blood glucose levels and liver functions and may improve the pathogenesis of NAFLD.
