![]() ![]() O 2 and CO 2 prices and consumption rates determine which configuration is best. All three configurations lead to gas supply costs in the same order of magnitude. Three different gas supply configurations were identified: Air supplemented with O 2, a mixture of O 2 and CO 2, and air supplemented with CO 2. The approach is demonstrated for fumaric acid fermentation with Rhizopus delemar, which consumes O 2 and can theoretically produce or consume CO 2. For the different configurations that were identified, all gas flow rates can be calculated in terms of other process parameters such as optimal concentrations of the gaseous compounds in the liquid phase, top pressures of the fermentation, and consumption/production rates. In this study, we present a methodology to identify and theoretically compare different configurations to supply mixtures of gaseous compounds to fermentations that consume these gases. However, a simple methodology to compare different gas supply strategies using gaseous substrates from different sources is missing. Gaseous substrates such as O 2 and CO 2 are often required in fermentation processes. ![]()
