Abstract:
     The method for producing citric acid with stalk or stem f crops includes such technological steps as breaking to 60-80 meshes, pulping, degradation, press filtering to remove non-chlorine extractives, fermentation by inoculation of bacterial strain, extraction and purification by conventional "calcium salt method", and features full use of rich cellulose and protein the stalk or stem contains to make cellulose be degradated into glucose, releasing starch and protein from stalk or stem by destroying cell walls, and no need of bran in fermentation.
