%X The cells of Aspergillus niger W1-2 were immobilized in calcium alginate gel for the production of citric acid. The effect of carbon sources (sucrose, glucose lactose) and their concentrations on citric acid production were investigated. The experimental results showed that the souroce was more suitable carbon source than glucose and lactose. Immobilized A. niger cells needed a lower initial sourse concentration (120g/ L) than free cells (140g/L) in order to obtain maximal yield of citric acid. Morever, the carbon sucrose concentration had more remarkable effect on citric acid production with immobilized cells than with free cells.
