Fig. 2.

Growth and lysis curves of pPG-2-hocb/L. casei 393 and pPG-2/L. casei 393 following induction. pPG-2-hocb/L. casei 393 and pPG-2/L. casei 393 were cultured in MRS medium at 37 °C. Expression of the lysis gene hocb was induced with xylose. The optical density (OD₆₀₀) of the culture was monitored at the indicated time points for a period of 88 h after the addition of xylose. OD₆₀₀ values are shown in the graph. n = 3; Error bars indicate ± SD
