Isoprenol production from p-coumarate in the engineered P. putida. A p-Coumarate catabolic pathway; B Isoprenol production by engineered P. putida (JPUB_019977). EZ-rich medium was used as the base medium by changing the carbon source to 1% or 2% p-coumarate. The blank EZ-rich medium without any carbon sources was used as a control. Error bars indicate one standard deviation of triplicates. The initial OD₆₀₀ of 0 h was set at 0.05. Isoprenol levels were not detectable at 0 h
