Uncoupling of rhamnolipid production and cell growth of P. putida in a 50 mL baffled flask. (a) Fermentation characteristics including cell growth (■) and course of rhamnolipid (▲) and glucose (♦) concentrations and their respective fitted courses. CDW, cell dry weight. (b) Specific rates resulting from the fitted experimental data. The black line represents the course of the growth rate, while the dashed line and the dotted line show the specific glucose uptake rate and the specific rhamnolipid production rate respectively.
