The invention discloses a corynebacterium glutamicum for producing gamma-aminobutyric acid, and a building method and application thereof. A glutamate decarboxylase gene gadB for synthesizing gamma-aminobutyric acid in lactobacillus plantarum and a glutamate dehydrogenase gene gdh for synthesizing L-glutamic acid in corynebacterium glutamicum are subjected to tandem expression and are guided intothe corynebacterium glutamicum; the corynebacterium glutamicum for producing gamma-aminobutyric acid produced by fermenting the corynebacterium glutamicum subjected to the gene tandem expression can effectively achieve the goal of efficiently producing gamma-aminobutyric acid by a biological method; safety and reliability are realized; and the production cost can also be obviously reduced.

The invention discloses a beef cattle unconventional feed and a preparation method thereof. The beef cattle unconventional feed comprises fat powder, stone powder, calcium hydrophosphate, sodium chloride, baking soda, magnesium oxide, urea, a flavoring agent, a compound enzyme preparation, corn, glutamic acid residues, DDGS, bran, cottonseed meal, corn bran and germ meal. The preparation method comprises the steps of raw material treatment, mixed sterilization, complex enzyme preparation addition, granulation and grading. A large amount of unconventional feeds are used in the raw materials, sothat the feed cost is greatly reduced, and other raw materials are compounded according to the characteristics of the adopted unconventional feeds; and the compound enzyme preparation is used, not only can improve the absorption of the feed for beef cattle, but also reduces the anti-nutritional effect brought by the feed raw materials, so that the beef cattle can better absorb nutrient substances.

The invention provides a biodegradable chelating agent and a preparation method thereof. The preparation method is characterized by comprising the following steps: 1) firstly, weighing chloroacetic acid and water, then slowly dropwise adding liquid caustic soda while controlling the temperature not to exceed 45 DEG C, and reacting to prepare sodium chloroacetate; (2) preparing a disodium L-glutamate solution by reacting metered deionized water, L-glutamic acid and caustic soda liquid, adding a catalyst, and then heating to 85 DEG C; (3) simultaneously adding the material in the step (1) and the prepared liquid caustic soda into the mixture in the step (2), controlling the dripping speed of the material and the prepared liquid caustic soda and the pH value of a reaction system, and controlling the pH value to be 9.5-10.5; and 4) after the dropwise addition is finished, reacting for 1 hour, then heating to 95 DEG C, continuously reacting for 3 hours, and after the reaction is finished, cooling to room temperature to directly obtain a finished product of the GLDA green chelating agent solution. The operation is simple, the process is stable, the product quality is high, the performance is good, and the biodegradable chelating agent has huge application prospects and market economic benefits.

The invention relates to a method for preparing a bacterial fertilizer from glutamic acid fermentation waste liquid and application of the bacterial fertilizer, belonging to the technical field of vegetable straw mulching. The method comprises the following steps: S1, collecting vegetable straw waste and then cutting the collected vegetable straw waste into sections so as to obtain straw waste A;S2, mixing the glutamic acid fermentation waste liquid, the straw waste A and water to obtain a mixture A; S3, adding saccharomycetes, lactic acid bacteria, bacillus subtilis and trichoderma aureoviride into the mixture A, and carryin gout natural fermenting to obtain a fermented material A; and S4, adding an organic nitrogen source into the fermented material A, and carrying out sealed fermentation to obtain the zymophyte fertilizer. The invention also provides the application of the zymophyte fertilizer prepared by using the method in promoting vegetable growth. According to the invention, the industrial glutamic acid fermentation waste liquid and agricultural vegetable straw waste can be treated at the same time, and the prepared zymophyte fertilizer is rich in nutrients and good in economic benefits.

The invention discloses a refining process of monosodium glutamate. The process comprises the following steps of: firstly, taking corns as a raw material; fermenting, separating and extracting to obtain glutamic acid; then mixing the glutamic acid with sodium carbonate in a water environment to obtain a neutralized solution; then de-coloring the neutralized solution by utilizing a magnetic nano material and carrying out magnetic separation to obtain a de-colored solution; then de-coloring the de-colored solution again through an exchange column containing anion resin; and finally, crystallizing, separating and drying to obtain the monosodium glutamate. The refining process disclosed by the invention is simple and the quality of the monosodium glutamate is greatly improved; the industrial application value is high.
