摘　　要：衣康酸作为一种平台化合物,可被各行业广泛用于多种高附加值产品的生产,其更是具有替代传统石油基原料的潜力,在工业生产中有着重要地位与应用前景。目前,衣康酸主要由土曲霉深层好氧发酵生产,碳源、氮源、磷酸盐、金属离子、溶解氧、pH、温度等条件对其产量影响显著。在衣康酸生产中,原料成本高是阻碍其市场进一步扩大与发展的重要因素。木质纤维素原料来源广泛、价格低廉,是理想的低成本碳源底物。研究利用木质纤维素水解液作为替代碳源生产衣康酸有望降低生产成本,对推动其发展应用具有重要意义。Itaconic acid,a platform chemical,can be widely applied in various industries for kinds of high value-added products. It is one of the potential alternatives to the traditional petroleum-based material,which has an important position and application prospect in industrial production. At present,itaconic acid is mainly produced by submerged fermentation by Aspergillus terreus. A number of parameters have significant influence on the yield of itaconic acid,such as carbon source,nitrogen source,phosphate,metal ion,dissolved oxygen,pH,and temperature. The high cost of raw material is a crucial factor which impedes the expansion and development of the itaconic acid market in industrial production. Lignocellulose is a widely available and a promising low-cost substrate. The research of lignocellulosic hydrolysate as a substitute carbon source to produce itaconic acid is expected to reduce the production cost,which is of great significance to promote the development and application of itaconic acid.
