Abstract d -Glutamate was produced from l -glutamate by two successive cellular reactions with a glutamate racemase produced by Escherichia coli TM93 harboring a plasmid containing a glutamate racemase gene from Lactobacillus brevis ATCC 8287 and a glutamate decarboxylase produced by E. coli ATCC 11246. l -Glutamate was first racemized to dl -glutamate at pH 8.5 and l -glutamate was then decarboxylated at pH 4.2. Starting from 100 g/l of l -glutamate, 50 g/l of d -glutamate remained after 15 h reaction.
