FIG 2.

Time course gene expression analysis of select monooxygenase and dehydrogenase gene targets in pure cultures of Pseudonocardia dioxanivorans CB1190 during biodegradation of 1,4-dioxane following enrichment on AMS medium supplemented with 20 mM glucose. The transcripts of DXMO and ALDH together varied with 1,4-dioxane, whereas transcripts of PrMO were high only when 1,4-dioxane was undergoing active transformation at lower concentrations below 50%. PHE is not displayed because transcripts from each sampling point were below the detection limit. Error bars represent the standard deviations of three replicates.
