Study on the Production of Oligofructose from Sugarcane Molasses Catalyzed by Whole Cell of Aspergillus niger
In order to explore the change rule of oligofructose(FOS)production by Aspergillus niger,single factor experiment was used to detect the content of FOS by HPLC.The results showed that the optimal conditions for FOS production were citric acid buffer,pH 6.0,wet mycelium age 48 h,whole cell catalyst concentration 120 g/L,substrate sucrose concentration 400 g/L,and conversion temperature of 50℃.Under these conditions,the yield of FOS reached 201.23 g/L,which was higher than the reported production of 160 g/L oligofructose from molasses.
