摘　　要：以黑曲霉(Aspergillus niger)XSY0607为试验材料,利用纤维素作为碳源通过液体深层发酵,对其进行产生柠檬素研究。试验结果表明:在7L小型发酵罐中接入种龄为1d的种子培养液、30℃通风搅拌培养5d的培养条件下,其适合产酸的条件为:水稻秸秆粉6%、蛋白胨5%、聚乙二醇0.1%及初始pH值为6.5,该试验结果为黑曲霉XSY0607菌株利用纤维素作为原料发酵生产柠檬酸的工业化生产和应用提供了一定的参考依据。Taking Aspergillus niger XSY0607 as experimental material, citrin production was studied by using submerged fermentation with cellulose as carbon source. Results showed that 1d aged seed culture was inoculated in 7L small fermenter and ventilation mixing cultured 5d in 30℃. Then optimum conditions for producing acid were rice straw powder 6%, peptone 5%, polyethylene gluvol 0.1% and initial pH value 6.5. It provides some references for industrial production and application of citric acid with cellulose as fermentation material based on Aspergillus niger XSY0607.
