Reaction condition optimization for conversion of L-PA 1 (20 mM) to (S)-7 by the designed E. coli (RFP-DEA-CGS) and E. coli (MVTA) consortium. A Effect of different pH on the conversion of (S)-7; B effect of different temperature on the conversion of (S)-7; C effect of glucose concentration on the conversion of (S)-7; D effect of R-MBA concentration on the conversion of (S)-7; E effect of different cell density of E. coli (RFP-DEA-CGS) and E. coli (MVTA) on the conversion of (S)-7; F effect of different L-PA 1 concentration on the conversion of (S)-7
