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.
