Sucrose influences the microbial structure and assembly of the oral microecology. (a) The microbial richness as revealed by OTU number. (b) Venn diagram showing shared OTUs among biofilms treated without/with sucrose, lactose and glucose. (c–e) The PCoA and dissimilarity analysis (including Adonis and ANOSIM) of polymicrobial oral biofilm among groups. Each dot stands for a biofilm sample. (f) Network inferences of microbial relationships in biofilms without/with sucrose, lactose or glucose treatment. Each node represents an OTU, and each edge represents a significant pairwise association. Red lines indicate synergistic relationships while green lines represent antagonistic relationships (n ≥ 4; ns, not significant; OTU, operational taxonomic unit; PCoA, principal coordinates analysis).
