Classification of the identified proteins into role categories. a Venn diagram showing the number of proteins differentially expressed (fold change ≥ 2; p-value ≤ 0.05) at 24 h and 48 h of the mcl-PHAs synthesis bioprocess as compared to the Pseudomonas putida KT2440 growth stage (8 h). Three proteins set groups were created representing proteins which the abundance was changed only at 24 h, at both time-points and only at 48 h. b Functional classification of identified proteins according to their predicted and unknown functions. The pie charts illustrate the percentage of proteins in each group accounted for the total number of proteins with changed expression. The fields which illustrate the up-regulated proteins were dotted, whereas the field with down-regulated proteins were solid
