Effect of the C:N ratio and different carbon sources on production of PHB and EPS.
A Scatter plot depicting the production per C molecule and C:N ratios of PHB and EPS under aerobic condition with 36 C sources. No clear tendency can be observed from 0 to 5 using the C:N ratio as reference. With C:N ratio above 5:1 a clear increase in the yield is noticed showing the highest yields when C:N ratios are higher for PHB production. B Comparison of the yields per C molecule in the presence and absence of oxygen. Most of the yields are concentrated in the center of the plot, meaning that the yields are remarkably similar independently of the oxygen concentration. C PCA plot displaying the two first component scores of the C:N ratios considering the PCA coefficients of PHB and EPS under aerobic conditions. The PCA represents 99% of the variability of the data. Two main clusters can be identified, the cluster of the EPS (left side) and the cluster of the PHB (right side). D First two component scores of the C:N ratio PCA under aerobic conditions, considering the PCA coefficients of C sources. The compounds were grouped by their common functional groups. Interestingly, two main clusters were recognized, the common functional groups with N (left) and the compounds without N in their chemical composition (right).
