FIGURE 1.

Soluble fractions of the C-sources and mineralization rate of P. putida grown in the absence (No SPs) and presence of SPs and metabolizing glucose or phenanthrene as the sole C and energy source. (A,B) Depict the soluble carbon and the mineralization rate, in the cultures grown in the presence of phenanthrene. (C,D) Depict the soluble carbon and the mineralization rate, in the cells grown in the presence of glucose. Vertical bars represent standard deviations (n = 3), statistically significant differences with respect to the cultures containing no SPs (black bars) are also reported (ns, non significant, ^∗p < 0.05, ^∗∗p < 0.01, ^∗∗∗p < 0.001).
