Fig. 2From: Metabolic engineering of Rhodococcus jostii RHA1 for production of pyridine-dicarboxylic acids from ligninGrowth curves (cfu, right hand scale) and titres of 2,4-PDCA production from 2 L bioreactor growths of R. jostii RHA1 wild-type (blue) and R. jostii DpcaHG containing pTipQC2ligAB (orange), and titres of 2,5-PDCA production by R. jostii wild-type (gray) and R. jostii DpcaHG containing pTipQC2praA (yellow), grown on M9 minimal media containing 1% wheat straw lignocellulose. Left hand scale shows titre (in g/L) of 2,4-PDCA or 2,5-PDCA product. Titres in g/L calculated from HPLC peak size, compared with authentic standards. HPLC traces are shown in Additional file 1: Figure S6. Data shown are averages of two measurements from a single experiment, and are representative of several experiments conducted similarlyBack to article page
