Result visualization of principal component analysis on the antioxidative system under acid treatments. In the figure, Acid1 represents a moderate acid treatment of pH 5.5, while Acid2 represents a very strong acid treatment of pH 5.0 (for strains GL6, JD, and NC2) or 4.5 (for the other strains), with the control of pH 7.0. Different shapes indicate different microbial strains in panel A, while different colors indicate the acid treatments in all the three panels. In each of panels B and C, different lowercase or upper letters indicate significant differences among the acid treatments at p < 0.05. The abbreviations SOD, CAT, GPX, GR, MDA, GSH and GSSG stand for superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, malondialdehyde, reduced glutathione, and oxidized glutathione, respectively.
