Figure 2.

Volcano plot distribution of proteins identified in (A) Citrobacter freundii (C) (B) Citrobacter spp. (C2) and (C) lactic acid bacteria (L) treatment in comparison to saline control (S). The Y-axis shows the–log10 transformation of the P-values for each of the respective proteins. The X-axis represents the log2 transformation of the fold difference between C, C2, or L treatments and S. The red squares indicate proteins that were identified by the volcano plot analysis (shown by the 2 solid black lines separating the points) concerning the magnitude of P-value to fold difference. The blue squares indicate the rest of the proteins which were significantly different (P < 0.05 or [−log10 (P-value)] > 1.3).
