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
[0004] The development and application of fertilizers in my country is the main stage from farmyard manure to the use of inorganic fertilizers. Because farmyard manure has many pollution sources and a large amount of transportation, 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

Abstract

The invention belongs to the field of fermented waste liquid treatment in the biological fermentation industry and discloses a fertilizer prepared by utilizing threonine fermented wastes. The fertilizer is prepared by the following steps: (1) preparing threonine fermentation liquor; (2) filtering and discoloring; (3) separating crystals and a mother solution; (4) hydrolyzing mycoprotein; (5) preparing feed liquid A; and (6) preparing the fertilizer. According to the fertilizer, amino acid fermented wastes are effectively utilized, the production cost of the fertilizer is reduced, the wastes are changed into valuable materials, the fertilizer efficiency is lasting, and the fertilizer is superior to like products in the market.

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. [0002] Background technique [0003] 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. [0004] The development and application of fertilizers in my country is the main stag...
