Itaconic acid production from liquefied corn starch by the transformants of pXH61 and pXH59. The transformants were screened using liquefied corn starch (corresponding to 140 g/L glucose) as the carbon source on a rotary shaker at 37°C for 72 h. Three independents experiments were performed for each strain. The itaconate titers were determined by HPLC.
