Problems solved by technology

The waste generated in the xanthan gum production process, including bacterial protein and high-concentration wastewater, is difficult to treat 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

Abstract

The invention belongs to the field of fermentation waste liquid treatments in biological fermentation industry, and discloses a preparation method of a compound mixing fertilizer containing xanthan gum fermentation waste. The preparation method comprises: 1) xanthan gum fermentation waste filtration; 2) hydrolysis; 3) microbial preparation A preparing; 4) microbial preparation B preparing; 5) fermentation broth A preparing; 6) fermentation broth B preparing; 7) regulator preparing; and 8) uniform mixing and drying. According to the present invention, the xanthan gum fermentation waste is used, the preparation method is simple and feasible, the prepared fertilizer has the multi-effect function, and the application prospect is broad.

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 preparation method of compound fertilizer containing xanthan gum fermentation waste. Background technique [0002] Xanthan gum is a high-viscosity water-soluble polysaccharide produced by Xanthomonas bacterium through aerobic fermentation of carbohydrates as the main raw material. The modern production of xanthan gum is based on pure culture medium under strict control conditions It is produced by fermentation under high temperature. Because the polysaccharide has high viscosity, rheological thixotropy and stable physical and chemical properties, and is non-toxic, it has broad market prospects as an additive in the field of daily chemistry, and is widely used in food, medicine, oil production, Textile, ceramics, printing and dyeing, spices, cosmetics and fire protection and other fields. The waste generated ...
