A kind of trichoderma fermentation substrate based on monosodium glutamate waste liquid and its application

Abstract

The invention discloses a trichoderma fermentation substrate based on aginomoto waste liquid. A preparation method of the trichoderma fermentation substrate is characterized by concentrating glutamic acid mother liquid obtained after producing aginomoto, then adding inorganic nitrogen source, phosphorus sources, potassium resources and organic matters, and enabling the final fermentation substrate to be prepared from 6-7% of nitrogen, 2-3% of phosphorus, 0.5-1.0% of potassium, greater than or equal to 35% of organic matters and less than or equal to 30% of water, wherein the pH value is 6.5-7.0. The glutamic acid mother liquid is prepared from the following dry substrate components: 14% of nitrogen, 1.0% of phosphorus, 1.8% of potassium and 48% of organic matters, wherein the Baume degree is 17 degrees Be, and the pH value is 3.0. The trichoderma is added into the fermentation substrate and has synergistic effect on exertion of fertilizer efficiency of a plant growth substrate; the aginomoto residue in the production of aginomoto can be changed from waste into wealth; the pollution to the environment caused by emission of the aginomoto residue in the environment is reduced; the yield of trichoderma conidia is increased; the conidium production time is shortened; the trichoderma conidia can be efficiently produced by the aginomoto residue.

Description

technical field [0001] The invention relates to a method for utilizing monosodium glutamate waste liquid, in particular to a trichoderma fermentation substrate based on monosodium glutamate waste liquid and its application. Background technique [0002] According to the survey, there are more than 200 large and small monosodium glutamate production enterprises in my country at present, with a production scale of 3 million tons per year. According to analysis, for every ton of monosodium glutamate produced, there will be 3-4 tons of high-concentration organic wastewater, from which 200-250Kg of monosodium glutamate residue can be extracted. In the past, these wastewaters were usually discharged directly, but such highly nutritious organic water is harmful to water areas. And ecological environment pollution is immeasurable. After separation and recycling of these wastewater, 200,000 tons of MSG residues can be obtained. These MSG residues can be made into organic fertilizers...

Problems solved by technology

[0004] The present invention aims at the deficiency of the high cost of fermentation substrate in the current production of Trichoderma conidia and the lack of practice of developing the residue derived from monosodium glutamate production waste liquid into Trichoderma microbial fertilizer, and provides a kind of high-yielding Trichoderma conidia and The Trichoderma fermentation substrate that shortens the sporulation cycle and its application solves the environmental pollution caused by the discharge of monosodium glutamate residues into the environment, greatly reduces the cost of Trichoderma conidia fermentation, and improves the efficiency of Trichoderma fermentation. Lay the foundation for further development of Trichoderma monosodium glutamate residue microbial fertilizer
