Fig. 1

The degradation of 0.10 mM PCA by different strains. The symbols used in the graph represent different strains as follows: (ring), PCA control; (triangle), PCA with strain WH101; (Right-Pointing Triangle), PCA with strain WH102; (black filled ring), PCA with strain WH103; (down-pointing triangle), PCA with strain WH104; (diamond), PCA with strain WH105; (Left-Pointing Triangle), PCA with strain WH106. Error bars represent the standard errors from three replicates. A (black asterisk) indicates a statistically significant difference between the PCA treatment-line and PCA control-line(P < 0.05).
