Principal components analysis (PCA) and partial least squares discriminant analysis (PLS-DA) score plots of secondary metabolites extracted from fermentation filtrates of mono- and co-cultures. (A) PCA score plots in positive ion mode, (B) PCA score plots in negative ion mode, (C) PLS-DA score plots in positive ion mode, and (D) PLS-DA score plots in negative ion mode. B1, fermentation filtrate of B. vietnamiensis B418 monoculture; T21, fermentation filtrate of T. harizanum TW21990 monoculture; BT21, fermentation filtrate of B418 + TW21990 co-culture.
