The invention discloses a novel production method for glutamic acid, belonging to the technical field of the production of amino acid. The novel production method for the glutamic acid comprises the following steps of: removing thalli and insolubles by means of high-speed disc separation; evaporating and concentrating separated glutamic acid material liquid through a multi-effect plate type evaporator at low temperature, wherein the generated secondary steam condensed water is used for fermentation ingredients of the glutamic acid; performing continuous isoelectric extraction on the glutamic acid in the evaporated glutamic acid concentrated solution; absorbing the glutamic acid by making supernatant fluid pass through ion exchange columns; performing isoelectric reextraction on the analyzed glutamic acid; inputting high-concentration wastewater into a fertilizer workshop for producing fertilizer; squeezing heavy phase (mycoprotein) through a plate frame, and granulating; and drying through a fluid bed, and thus producing high-protein feed. The novel production method for the glutamic acid has the advantages of low unit consumption of liquid ammonia and sulfuric acid, high extraction yield of the glutamic acid, less ion exchange investment and the like; and meanwhile, the purity of the extracted glutamic acid is high, sodium glutamate can be produced without crystalloblast, resources are fully used in the whole process, the aims of energy conservation and consumption reduction are achieved, and the novel production method for the glutamic acid has a wide application prospect.

The invention relates to biological agent for processing glutamic acid fermentation waste water. Mycoprotein is separated from glutamic acid fermentation liquid through a high-speed disc separator, bacteria removing liquid is gathered, the mycoprotein is precipitated, compound seed liquid is added to the mycoprotein for preparing probiotics, the waste water generated by extracting glutamic acid from the bacteria removing liquid is drained into a sewage processing system, compound microorganism bacterium agent is added to the waste water to perform advanced treatment, and the waste water is discharged after reaching the standard. The biological agent for processing glutamic acid fermentation waste water is economical and environmental friendly and has broad application prospect.

The invention relates to an environment-friendly process for treating glutamic acid fermentation wastewater. Glutamic acid fermentation broth is subjected to mycoprotein separation by a high-speed disc separator, a degerming liquid is collected, mycoprotein is precipitated, a composite seed solution is added to the mycoprotein for fermentation to prepare a probiotic preparation, wastewater generated by extracting glutamic acid by the degerming liquid enters a sewage treatment system, a compound microbial agent is added for deep treatment, and then the wastewater is drained up to the standard. The environment-friendly process for treating glutamic acid fermentation wastewater is economical and environment-friendly, and has broad application prospect.

The waste fermented liquid from glutamic acid production contains great amount of thallus, intermediate fermenting products and trace elements. The present invention provides the technological process of producing fermented fertilizer as one kind of organic-inorganic composite fertilizer with the waste fermented liquid from glutamic acid production. The technological process includes the steps of evaporating concentration, extracting ammonium sulfate, stirring mixing, drum pelletizing and stoving. The present invention has high economic benefit and environment benefit.

A feed additive for ruminants, comprising dried glutamic acid fermentation solubles, dried corn fermentation solubles, or a mixture of dried glutamic acid fermentation solubles and dried corn fermentation solubles, wherein said dried solubles have been dried to a total moisture content of less than 30% by weight at a temperature not less than about 80° F. and not more than about 900° F.

The invention relates to a special strawberry composite biological fertilizer as well as a preparation method and application thereof. The special strawberry composite biological fertilizer comprisesthe following components: EDTA-Ca (Ethylene Diamine Tetraacetic Acid), magnesium sulfate heptahydrate, EDTA-Mg, heptahydrate, EDTA-Zn, manganese sulfate monohydrate, EDTA-Mn, boric acid, EDTA-Fe, EDTA-Cu, soybean molasses, polyglutamic acid fermentation broth, chitosan oligosaccharide, algin, compound amino acid, humic acid, bacillus thuringiensis fermentation broth, bacillus megatherium fermentation broth, bacillus mucilaginosus fermentation broth and streptomyces jingyangensis fermentation broth. Through bacterium activation, seed liquid preparation, fermentation culture and compounding, thecomposite biological fertilizer is prepared, the composite biological fertilizer is applied to strawberry planting, and a diluted composite biological fertilizer liquid is sprayed at different growthstages of strawberry respectively. Due to synergetic effects of substances such as inorganic salts, organic matters and microorganisms, long lasting nutrient substances are provided to strawberry crops, absorption of nutrients in soil by plants is promoted, the fertilizer amount is reduced, and the chemical fertilizer cost is reduced.
