Figure 2From: Metabolic engineering of the fungal D-galacturonate pathway for L-ascorbic acid production The D-galUA inducible expression cassette and relative transcription of gaaA (blue squares), EgALase (red triangles) and MgGALDH (green circles) in the strain Δ gaaB - Eg - Mg ( PgaaA/C ) after the shift from pre-cultures to medium supplemented with D-galUA and D-xylose. Values were normalized to the expression of actin. Error bars represent ± SEM (n = 3).Back to article page
