AI Technical Summary

Technical Problem

Existing technologies fail to effectively utilize the synergistic effects of multiple functional bacteria in fish protein fermentation, resulting in high rates of destruction of amino acid active peptides, significant loss of active ingredients, and serious waste of resources. Furthermore, they fail to systematically and directionally enrich organic acids, affecting the fertilizer efficiency of liquid fertilizers and the control of environmental pollution.

Method used

A complex microbial synergistic fermentation system is adopted, including multiple functional microorganisms such as Lactobacillus reuteri and lactic acid bacteria. By controlling the fermentation time, fish protein fermentation liquid fertilizer rich in dipeptides and small molecule organic acids is generated in a targeted manner, realizing the efficient enzymatic hydrolysis and metabolism of amino acids and organic acids.

Benefits of technology

Significantly enhances the functionality and added value of liquid fertilizer, promotes plant growth, improves stress resistance, improves soil environment, and enhances fruit quality and economic benefits.

Abstract

The invention belongs to the field of biology, and particularly discloses a fish protein fermentation liquid fertilizer rich in dipeptide and small molecular organic acid and a preparation method of the fish protein fermentation liquid fertilizer, and the fish protein fermentation liquid fertilizer prepared by the method is rich in active peptides which are necessary for plant growth and development and comprise leucine dipeptide, glutamic acid dipeptide and proline dipeptide. The micromolecular organic acids comprise lactic acid, phenyl lactic acid and gamma-aminobutyric acid, and the composition and content of micromolecular metabolites are regulated and controlled by controlling the fermentation time, so that the regulation function of the fish protein leftovers as non-nutrient elements of the liquid fertilizer is exerted. High-value utilization of fishery waste is achieved, the content and composition of metabolites of the prepared liquid fertilizer are precisely regulated and controlled, the liquid fertilizer can remarkably promote growth of apple trees, the content and quality of soluble solids of fruits are improved, and the liquid fertilizer has multiple effects of nutrition, soil improvement and stress resistance enhancement.
