The broth was ultrafiltered (UF), and the retentate was diafiltered (DF) to wash out the remaining product. The dilute DF permeate was concentrated by reverse osmosis (RO). Recovery of glutamic acid by UF (Ruf) was a function of the volume concentration ratio (VCR); Ruf= 1.052 ¡V 1.048/VCR. High VCR, however, decreased UF flux (J) (J = 14.2 ¡V 5.4 In VCR). The rate of recovery by DF was a function of the turnover ratio. A linear relationship between flux and pressure was found during RO. Separation of glutamic acid from bacterial cells by membrane processing could improve the efficiencies of subsequent evaporation and crystallization processes. Copyright ? 1987, Wiley Blackwell.
