Redundancy analysis (RDA) of physical factors and samples based on the bacterial community (A,B) and the abundance of KEGG pathways (C) in different smoked horsemeat sausages. In RDA, an acute angle indicates a positive correlation while an obtuse angle indicates a negative correlation between the species and environmental factors. (B) A red circle represents a significant bacterial genus, while the circle space represents the abundance of the species. (C) Bacterial functions at levels 1 and 2 and carbohydrate metabolism at level 3 are shown.
