Fed-batch fermentation of nipa sap to acetic acid by Moorella thermoacetica (f. Clostridium thermoaceticum)
An efficient process for conversion of nipa sap to acetic acid was developed. Nipa sap was hydrolyzed with invertase and provided glucose as well as fructose as main sugars. Batch fermentation of glucose and fructose was inadequate with increased substrate concentration. By contrast, fed-batch techn...
