Experiment of L-Phenylalanine Fermentation in New 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. Compared with in the traditional agitated bioreactor, the biomass(taken its measure by OD value) of microbe fermented in new bioreactor is enhanced from 0.40 to 0.54, moreover, the average rate of L-Phe production by the preparation method of PPA-transamination is raised from 70% to 75%.
