Problems solved by technology

Threonine is mainly used as a feed additive, and its production steps are concentration, crystallization, and extraction of bacterial protein. However, the bacterial protein and mother liquor produced in the process are difficult to process and costly, and it is difficult to obtain cost-effective by-products
The applicant's previous patented technology "a fertilizer prepared from threonine fermentation waste" used the method of hydrolyzing bacterial protein to prepare amino acid chelated fertilizer, but this method contained metal ions and was not suitable for the preparation of bacterial fertilizer
[0003] 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 ecological environment
At present, inorganic compound fertilizers containing nitrogen, phosphorus and potassium are mostly used in the market. The compound fertilizer has comprehensive fertilizer effects, but there are also defects such as short-lasting fertilizer effects and easy loss; more importantly, the current price of compound fertilizers is relatively high, which brings great harm to farmers. How to reduce fertilizer costs and increase farmers' income is a technical problem that modern agriculture needs to solve

Embodiment 1

[0024] The compound fertilizer that utilizes threonine fermentation waste to prepare, it comprises the steps:

[0025] 1) The threonine fermentation waste produced by the biological fermentation of threonine (threonine is prepared by biological fermentation, and the waste after threonine is collected, including bacterial protein, sugar and ammonia nitrogen) is filtered and collected Bacterial proteins and waste water;

[0026] 2) Dry the bacterial protein, pulverize it into powder, then put it in the reaction tank, add 5mol / L hydrochloric acid, subject to the raw material, stir and hydrolyze at 60°C for 24 hours, the stirring speed is 300 rev / min, neutralize the residual hydrochloric acid with ammonia water after the reaction is terminated, and control the pH of the solution to be 6.8-7.2;

[0027] 3) Cultivate Trichoderma chrysogreen, Pseudomonas aeruginosa, and Candida to a concentration of 1×10 7 bacterium solution per ml, and then mixed according to the volume ratio of 3...

Abstract

The invention belongs to the field of treatment of fermentation wastewater in the biological fermentation industry and provides compound fertilizer prepared from waste through fermentation with threonine. The preparation of the compound fertilizer comprises steps as follows: filtering of the waste, hydrolysis, preparation of fermentation broth and freeze drying. The prepared compound fertilizer has the effects of nitrogen fixation and water retention, a lasting fertilizer effect and a certain weeding function and is environment-friendly and pollution-free, and both yield and revenue of crops can be increased.

Description

technical field [0001] The invention belongs to the field of fermentation waste liquid treatment in the biological fermentation industry, and in particular relates to a fertilizer prepared from threonine fermentation waste. Background technique [0002] Threonine is an essential amino acid, which is the second limiting amino acid in pig feed and the third limiting amino acid in poultry feed. With the wide application of lysine and methionine synthetic products in compound feed, threonine has gradually become an The main limiting factor for the growth of livestock and poultry. Threonine is mainly used as a feed additive. Its production steps are concentration, crystallization, and extraction of bacterial protein. However, the processing of bacterial protein and mother liquor produced in the process is difficult and costly, and it is difficult to obtain cost-effective by-products. The applicant's previous patented technology "a fertilizer prepared from threonine fermentation ...
