Figure 1From: A process optimization for bio-catalytic production of substituted catechols (3-nitrocatechol and 3-methylcatecholSchematic representation of bioreactor/recovery loop used for biotransformation. (a) Two-step bioreactor/recovery loop used for biotransformation of 3-nitrophenol to 3-nitrocatechol by strain P. putida F1. (b) Single- step bioreactor/recovery loop used for biotransformation of toluene to 3-methylcatechol by E. coli expression clone (pDTG602).Back to article page
