Problems solved by technology

[0006] The development and application of fertilizers in my country is from farmyard manure to the use of inorganic fertilizers as the main stage. Because farmyard manure has many pollution sources and large transportation volume, it is time-consuming and laborious to operate and the effect is not particularly obvious; while inorganic fertilizer has a single component and a relatively low utilization rate. Low, and often cause soil compaction and soil erosion to pollute water sources, affecting the ecologi...

Embodiment 1

[0029] A biological bacterial fertilizer prepared by utilizing glutamic acid fermentation waste is prepared according to the following method:

[0030] Step 1) Filtration of the fermentation broth: the glutamic acid fermentation broth is filtered and sterilized by a microfiltration membrane, and the retentate and the filtrate are collected respectively; The retentate and the concentrated solution are combined into feed solution A for subsequent use; wherein, the microfiltration membrane is an inorganic ceramic membrane, the molecular weight cutoff is 2000MW, and the microfiltration temperature is 40°C; the molecular weight cutoff of the ultrafiltration membrane is 300MW, and the ultrafiltration temperature is 40°C;

[0031] Step 2) Decolorization, concentration and crystallization: The permeate obtained in step (1) is pumped into a decolorization tank for decolorization treatment, and activated carbon with a mass of 0.5% of the permeate is added to the decolorization tank, and ...

[0047] Fertilizer efficiency test of the fertilizer of the present invention

[0048] 1. Fertilizer efficiency test for planting rice:

[0049] Two treatment experimental fields were set up, the planting time was 2013, and the planting area was one mu, which were the control group and the experimental group. Control group: compound fertilizer (N23-P7-K6); experimental group: biological bacterial fertilizer prepared in Example 1; the amount of fertilizer used in each group of test fields is 50kg, and the planting conditions are exactly the same. Yield increase rate; simultaneously detect the number of grains per ear, 1000-grain weight and the number of empty rice grains. The test results are shown in Table 1:

Abstract

The invention belongs to the field of treatment of fermentation waste liquid in biological fermentation industry and discloses a biological bacterial fertilizer prepared from glutamic acid fermentation wastes. The fertilizer is prepared by the following steps: S1) filtering the fermentation liquid; S2) decoloring, concentrating and crystallizing; S3) hydrolyzing; S4) preparing slurry B; and S5) preparing the biological bacterial fertilizer. The biological bacterial fertilizer disclosed by the invention effectively utilizes amino acid fermentation wastes, thereby lowering the production cost of the fertilizer and turning wastes into wealth. Moreover, the fertilizer which is durable is superior to similar products on the market.

Description

[0001] technical field [0002] The invention belongs to the field of fermentation waste liquid treatment in the biological fermentation industry, and particularly relates to a biological bacterial fertilizer prepared by using glutamic acid fermentation waste. [0003] Background technique [0004] Glutamate is an acidic amino acid. The molecule contains two carboxyl groups, and the chemical name is α-aminoglutaric acid. Glutamate was discovered by Rissson in 1856. It is a colorless crystal with an umami taste. It is abundantly present in cereal proteins and is also abundant in animal brains. Glutamate plays an important role in protein metabolism in organisms and participates in many important chemical reactions in animals, plants and microorganisms. Sodium glutamate, commonly known as monosodium glutamate, is an important umami agent that enhances aroma. Sodium glutamate is widely used in food flavorings, either alone or in combination with other amino acids. Used in ...
