Fig. 4From: Comparative metabolomics analysis of amphotericin B high-yield mechanism for metabolic engineeringThe VIP plot of the (O)PLS-DA model generated from the intracellular metabolites. The VIP values represented the contribution of metabolites, and the higher the VIP value of a metabolite, the more contribution that this metabolite showed. The variables with VIP value greater than 1 are separated from the others by a red lineBack to article page
