Fig. 1From: Biosynthesis of rhamnolipid by a Marinobacter species expands the paradigm of biosurfactant synthesis to a new genus of the marine microfloraThree-dimensional response surface plot modelling the effect of varying media pH and salt concentration on a biosurfactant yield and b cell-free supernatant surface tension. The different coloured areas of these plots represent various bands for either predicated yield or predicted surface tension. The values of each band are provided in the key next to each panelBack to article page
