NOVELTY - Preparing protein granules involves filtering lysine fermentation broth. The broth is filtered by a filter having pore size 1 mm. The obtained filtrate and solid fiber material are. The obtained filtrate is again filtered by microfiltration. The obtained filtrate and retentate are collected. The obtained filtrate is again filtered by ultrafiltration. The obtained filtrate and concentrate are collected. The obtained filtrate is evaporated to obtain one quarter volume of liquid and then crystals. Centrifugation is performed to the obtained materials.    USE - Used in feed and fertilizer (claimed).    ADVANTAGE - The protein granules have high purity and can replace commercially available yeast powder products. The process uses waste mother liquid from lysine production.    DETAILED DESCRIPTION - Preparing protein granules involves filtering lysine fermentation broth. The broth is filtered by a filter having pore size 1 mm. The obtained filtrate and solid fiber material are. The obtained filtrate is again filtered by microfiltration. The obtained filtrate and retentate are collected. The obtained filtrate is again filtered by ultrafiltration. The obtained filtrate and concentrate are collected. The obtained filtrate is evaporated to obtain one quarter volume of liquid and then crystals. Centrifugation is performed to the obtained materials. Lysine base crystals and effluent are collected. The retentate, concentrate and effluent are combined, to obtain waste mother liquor. The waste mother liquor is heated at 100 degrees C for 10 minutes. The obtained material is denatured bacterial solution. The obtained material is cooled at room temperature. The obtained material is centrifuged at 4000rotation/min for 12 min. The supernatant liquid and lower cells are collected. The lower cells are dried in vacuum at 40 degrees C. The obtained material is weighed and is provided with ultraviolet irradiation for 5 minutes. The obtained material is placed in reactor and is stirred. Hydrochloric acid solution (1M)is added twice to the amount of obtained material. The obtained material is rotated in reactor at 100r/min for 15 minutes. The obtained material is centrifuged with a disk separator to remove cell walls. The centrifugation is performed is at 3000r/min for 5 min. The supernatant is collected. The supernatant is dried by spray granulation fluid bed. Protein granules are obtained. The obtained solid fiber material, supernatant liquid and merged cell walls are combinied. The obtained material is naturally sedimented for separation of solid and liquid. The obtained materials are precipitate and supernatant. The obtained precipitate, rice bran, egg shell powder and wheat bran is mixed in 5: 2: 1: 1 mass ratio, respectively. The mixture mass 3% and ammonium hydroxide is mixed. Purified water is added to adjust moisture content to 50% of the mixture. The obtained material is placed in a sealed environment for ammoniation for 72 hour. After ammoniation, the pH of obtained material is 5.0. Cellulose (2%) and xylanase (1%) is added to the mixture. The obtained material is uniformly mixed. Enzymolysis is performed to the obtained material for 20 hours at 100 degrees C. Enzyme inactivation of obtained material is performed at 30 degrees C for 5 minutes. The obtained material is air dried. and pulverized to obtain feed. Potassium humate, diatomaceous earth and straw powder is added into the obtained material. The obtained material is stirred and allowed to stand for 12 hours. Ammonia is added to the obtained material. The obtained materials are mixed and placed in a sealed environment for ammoniation for 72 hour. The obtained material is main ingredient. The main ingredient, monoammonium phosphate, poly-aspartic acid and zinc sulfate is mixed in 200: 10: 1: 1 mass ratio, respectively. The obtained material is placed in twin-screw extruder granulator. The obtaining material is packaged.
