PCA and PLS-DA score plot based on culture supernatant. (a) PCA score plot and (b) PLS-DA score plot generated using MetaboAnalyst based on culture supernatant in positive mode. PLS-DA models were validated using R 2 and Q 2 based on leave one out cross-validation (LOOCV). Five-component model was selected as optimized model with R 2 = 0.99 and Q2 = 0.99. The significance of the model was demonstrated by permutation test with 2000 testing iterations using separation distance and P value <0.001 was obtained.
