Selecting the host cell processing high substrate transportation ability. a Extracellular substrate (17-OHP) concentration for E. coli C43(DE3) (dark blue), E. coli MG1655(DE3) (black), S. cerevisiae CEN.PK2 (orange), Y. lipolytica ATCC201249 (red) and M. smegmatis mc²155 (green) over the time course. b The intracelluar (purple) and extracelluar (green) substrate amounts for E. coli MG1655(DE3) over the time course. The substrate 17-OHP was supplemented into the culture at the very beginning of the cultivation. Samples were taken every 8 h
