Abstract

Effects of different factors on itaconic acid fermentation were studied. The optimal temperature and initial pH for itaconic acid fermentation were 36-37 °C and 3.2-3.6, respectively. The effects of auxiliary organic nitrogen sources on itaconic acid fermentation were also studied. In the view of industrial production and economic benefits, wheat bran was selected as auxiliary nitrogen source.

Key words： itaconic acid; nitrogen source; temperature; pH
