Figure 6

Transcriptional analysis by RT-qPCR of the expression of lacT (blue bars), lacE (green bars), lacG (black bars) and lacF (red bars) in Lactobacillus casei wild type strain BL23 grown in sugar-free MRS containing galactose (Gal), N-acetylglucosamine (GlcNAc), N-acetyllactosamine (LacNAc), lactose (Lac), a mix of glucose and lactose (Glc + Lac) or a mix of glucose and N-acetyllactosamine (Glc + LacNAc). Cells grown in sugar-free MRS supplemented with glucose were used as reference condition. Data presented are mean values based on three replicates of at least two biological independent samples. Bars indicate standard errors. For each lac gene, significantly different values (P < 0.05) among culture conditions are marked by different lower-case letters.
