A method of producing succinic acid comprises growing a succinate producing microorganism in medium containing sodium ions an assimilable carbohydrate, other required nutrients and dissolved carbon dioxide at pH of about 5.8 to about 6.4. The succinic acid can be isolated from the fermentation broth if it is present in high enough concentrations by maintaining the pH at about 5.8 to about 6.4 and adding calcium hydroxide so that calcium succinate precipitates.
