Effects of strain YK-19 intervention on the gut microbiota of mice
In this study, 16S rRNA gene sequencing was performed to investigate changes in the gut microbiota of mice after intervention with Bacillus velezensis strain YK-19. Cecal contents were collected from experimental and control mice, and the bacterial community structure, diversity and differential taxa were analyzed to explore the regulatory effect of strain YK-19 on host intestinal microecology.
