Abstract

1. A process for producing the pure L-isomer of malic acid from neutralized fumaric acid under bioconversion conditions by free movable microorganisms in an aqueous solution of fumarate characterized in that said microorganisms are fungi, that the initial concentration of fumarate is 11 to 15 % by weight and that the concentration of L-malic acid at the time of harvesting is 100 to 170 g per liter of fermentation broth.
