Abstract

Citric acid production from degermed corn extrudate was investigated. The purpose was to raise citric acid productivity under different nitrogen sources. The extrudate fermentation broth was acquired for citric acid production by Aspergillus niger Co827 under inorganic((NH4)2SO4, NH4NO3, NH4Cl) or organic(urea, corn cinder) nitrogen sources. The test results showed: It was favorable for citric acid production under 3 g/L (NH4)2SO4 inorganic nitrogen sources or 1 g/L corn cinder organic nitrogen sources; Citric acid production adding corn cinder (citric acid productivity 9.82 g/100 g) was more than one adding (NH4)2SO4 (citric acid productivity 7.86g/100 g). To conclude, the above results provide useful data for raising citric acid productivity from degermed corn, cutting down production costs and increasing corn’s comprehensive utilization degree.
