Fig. 1From: Shake flask methodology for assessing the influence of the maximum oxygen transfer capacity on 2,3-butanediol productionSchematic illustration of the experimental setup. Cultivations are performed in multiple individual shake flasks in parallel. As indicated by different colors, four different experimental conditions are investigated in one experiment. Online measurement (a) of oxygen transfer rate (OTR), carbon dioxide transfer rate (CTR) and the respiratory quotient (RQ) is performed as duplicates in a respiration activity monitoring system (RAMOS). Offline samples (b) are taken from individual shake flasks, which are not returned to the shaker after samplingBack to article page
