1.14.14.89	additional information	reduction of soy isoflavones by use of Escherichia coli whole-cell biocatalyst expressing isoflavone reductase under aerobic conditions, optimization of the aerobic bioconversion conditions, overview. Addition of chloramphenicol significantly increases the bioconversion capacity of the recombinant Escherichia coli whole-cell, but addition of chloramphenicol does not increase the expression of S-DGR irrespective of whether the concentration of chloramphenicol is high. The maximal concentration of daidzein that the recombinant Escherichia coli whole-cell is able to convert efficiently is 0.8 mmol/l. The average bioconversion rate for daidzein is 85.0% and the yield of 2'-hydroxydaidzein is 0.545 mmol/l	745660
