Fig. 5From: Biodegradation of p-nitrophenol by engineered strainDegradation of 1 mM PNP. PNP was converted to β-ketoadipate via HQ pathway as designed. a Degradation of PNP and formation of HQ. The solid lines show the change of the metabolites in the engineered strain BL-PNP, and the dotted lines show the one in control strain. Black diamond, the degradation of PNP; black up-pointing triangle, the formation of HQ. b GC–MS analysis of β-ketoadipate concentration at different times in the engineered strain BL-PNPBack to article page
