Figure 1From: An in vitrobiofilm model system maintaining a highly reproducible species and metabolic diversity approaching that of the human oral microbiomeCorrespondence analysis showing reproducibility and 16S profile similarities within biofilm and saliva samples. Axis 1 explains 47% of the variation in the dataset; axis 2 explains 19% of the variation. Replicate biofilm samples representing batches 1 and 3 cluster closely together whereas batch-2 biofilms that derive from an SIP experiment cluster more distantly along the first ordination axis. Saliva-derived replicates (1 to 3) also show similar 16S diversity.Back to article page
