Time profiles of GABA synthesis from a 3 M and b 2 M crude l-Glu solution. a Time course where diamond, square and circle represent l-Glu concentration, GABA production and pH, respectively. b Repeated use of cells where square, circle and diamond represent cycle 1, cycle 2 and cycle 3, respectively; filled shapes GABA concentrations; open shapes residual l-Glu concentrations
