Abstract

Summary: The medium redox potential ( ) influenced the folate-limited growth of the growth response was maximal at an of +120 mV (pH 6·35). At raised serum folate would support less growth than pteroyl-glutamic acid, and the response to -methyl tetrahydrofolic acid was intermediate between them. Pteroylglutamic acid was not destroyed during 24 h incubation at 37 °C in medium with values between +40 and +440 mV. Destruction of -methyl tetrahydrofolic acid occurred within 24 h when the medium was greater than +125 mV. Folate was taken up rapidly by with an optimum at + 270 mV.
