Abstract

The production of fumaric acid in a novel fixed-layer fermenter using Rhizopus oryzae KCTC 6946 was studied. When yeast extract and corn steep liquor were used as nitrogen sources, fumaric acid produced was 6.4 g/L and 6.8 g/L, respectively. Compared with the flask cultivation, fumaric acid concentration was about 200% when yeast extract was used as a nitrogen source, but reached to 93% when corn steep liquor was used.
