Fed-batch fermentations of ES-1/pSC-08, ES-13/pSC-08, ES-134/pSC-08 and ES-1234/pSC-08. ES-1/pSC-08 (a), ES-13/pSC-08 (b), ES-134/pSC-08 (c), ES-1234/pSC-08 (d). Cell growth (filled square), l-serine concentration (filled circle), residual glucose concentration (up filled triangle), specific growth rate (open square), and l-serine productivity (open circle) are shown; the arrow at 8 h indicates the starting point of induction
