Figure 2From: Functional identification in Lactobacillus reuteri of a PocR-like transcription factor regulating glycerol utilization and vitamin B12 synthesisBiomass formation and sampling scheme in pH-controlled batch fermentations. Experiments were carried out in CDM in the presence (white squares) or absence (black square) of glycerol by L. reuteri transformed with pNZ7021 (empty plasmid, solid lines) or pNZ7748 (harboring lreu_1750, dashed lines).Back to article page
