Fish Scale Amino Acid Peptides for Burn-Free Asteraceae Growth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fertilizers for lettuce cultivation, particularly those derived from livestock by-products, pose risks of contamination and zoonoses, and composite fish materials lead to inconsistent quality and poor reproducibility, while excessive nutrient application causes fertilizer burn and tip-burn, affecting yield and growth efficiency.
Innovation Solution
Amino acid peptide solution produced by decomposing fish scales using Bacillus velezensis is applied to promote healthy and strong growth of Asteraceae seedlings, enhancing nutrient uptake and reducing the risk of fertilizer burn.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If livestock by-products are used to produce fertilizer, then fertilizer composition is obtained, but zoonoses contamination risk increases
Solution Approach 1:
The patent extracts and uses only fish scale by-products as the raw material for fertilizer production, completely eliminating livestock by-products from the process. This extraction of the harmful element (livestock by-products) while retaining the useful function (fertilizer production) resolves the contradiction between obtaining fertilizer composition and avoiding zoonoses contamination risk
Solution Approach 2:
The patent employs fish scales, which are typically discarded as waste, as the raw material. This use of low-value, easily obtainable waste material eliminates the need for expensive livestock by-products while maintaining fertilizer effectiveness, thereby resolving the contradiction between fertilizer quality and contamination risk
2Quantity of substance
If composite fish materials are used for fertilizer production, then fertilizer is obtained, but quality consistency deteriorates
Solution Approach 1:
The patent segments the fish by-product into a specific component (fish scales) and uses only that segment for fertilizer production. This segmentation from the complex composite fish materials allows for standardized processing and consistent quality, resolving the contradiction between fertilizer production and quality consistency
Solution Approach 2:
The patent focuses on using fish scales specifically, which have uniform composition and properties, rather than composite fish materials with varying compositions. This local quality approach ensures consistent fertilizer quality while maintaining production capability
3Productivity
If excessive nutrient fertilizer is applied to promote growth, then yield increases, but fertilizer burn occurs
Solution Approach 1:
The patent changes the chemical composition parameters of the fertilizer by using fish scale-derived amino acid peptides instead of conventional high-concentration nutrient fertilizers. This parameter change maintains effectiveness for promoting growth while eliminating the harmful effects of fertilizer burn and tip-burn
Solution Approach 2:
The patent converts the previously harmful effect of fish scale waste into a beneficial fertilizer product. By transforming fish scales into amino acid peptide solution through enzymatic hydrolysis, the waste material becomes a valuable growth promoter that eliminates the need for excessive nutrient application
4Quantity of substance
If fish scales are used as fertilizer, then fertilizer composition is obtained, but decomposition time increases
Solution Approach 1:
The patent introduces an intermediary substance (amino acid peptide solution) as the active component that accelerates the decomposition process. This intermediary enables rapid breakdown of fish scales into usable fertilizer components, resolving the contradiction between obtaining fertilizer composition and decomposition time
Solution Approach 2:
The patent replaces mechanical/physical decomposition methods with biological enzymatic hydrolysis. This substitution uses microbial enzymes to rapidly break down fish scale proteins into amino acid peptides, dramatically reducing decomposition time while maintaining fertilizer quality
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution promotes healthy and strong growth of Asteraceae seedlings, shortens harvest time, increases chlorophyll content, and improves yield without causing fertilizer burn, thereby optimizing field management and revenue per unit area.
Implementation Method 1
the fish scales contain about 50% collagen, most of which is produced into collagen peptides by enzymatic hydrolysis
Implementation Method 2
Bacillus velezensis is used to decompose fish scales and produce an amino acid peptide solution containing peptides and amino acids
Implementation Method 3
The amino acid peptide solution is applied to the Asteraceae so that not only seedlings of the Asteraceae family grow stronger and healthier, but growth of above ground part of the Asteraceae is promoted
