Study on Temperature Field of L-Phenylalanine Fermentation in Heat Pipe Bioreactor

Abstract:

L-phenylalanine fermentation (L-Phe) is produced by the preparation method of PPA-transamination using the ferment liquor, which is the production of the E.coli No.1 fermented in heat pipe bioreactor (HPBR), the technical indexes are superior. The temperature profile of ferment liquor in the period of microbe growth is well distributed, the mean difference in temperature is 0.08°C, while the maximum value is 0.4°C.Base on operational principle of heat pipe, HPBR solves many problems on heat transfer in traditional bioreactor: nonuniformity of temperature profile, inefficiency of heat transfer etc. The study in-depth on transfer process in HPBR will effectively accelerate exploitation for new-style bioreactor and advancement of biotechnology.
