Figure 7. 3D-bar growth representations of all the defective mutants with C₁₂–C₂₄ n-alkanes.

Values on the horizontal axis profile the genotype of the mutants with single or multiple deletions of alkane hydroxylases; The Y-axis specifies the tested n-alkanes, coloring from black to dark blue black. The Z-axis of bar altitudes represents the OD₆₀₀ for the viability of each mutant. Sharp contrasts were symbolized using arrows when both alkB1 and alkB2 were knocked out, and cultivated in C₁₆ and C₁₈ alkane media, respectively.
