Abstract
Pipecolic acid is an important precursor for piperidine ring derivatives. A lysine cyclodeaminase was used to catalyze L-lysine for L-pipecolic acid synthesis. To accelerate the catalytic rate, a PDMS microchip was designed and fabricated. Effects of microchannel size, microchannel length and liquid flow rate on catalytic rate were studied. The optimized conditions in microreactor were: microchannel size 200 |xm; microchannel length 124.8 cm;and liquid flow rate 100 μm/min. Under the optimized conditions, a pipecolic acid titer of 2.22 g/L was obtained after 44 h reaction, the reaction time reduced 1/3 in comparison with the reaction in shaking tube.
