Fed-batch cultivations equipped with exterior extraction modules. a Graphical diagram of the exterior extraction modules (three bottles) in fed-batch cultivation. b Time profiles of cell density (OD600) and styrene production titer. Closed circle, cell density (OD600); open circle, total styrene; open triangle, styrene from interior n-dodecane; closed square, styrene from reservoir A; closed diamond styrene from reservoir B; cross, styrene from reservoir C. Dashed line indicates the induction time point. The results are shown as the mean value ± standard deviation (SD) of two independent experiments
