Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current microbial deodorizing agents for livestock and poultry manure exhibit inadequate efficacy and slow response, failing to meet contemporary odor emission standards, particularly in terms of sulfur removal rates.
Innovation Solution
A composite deodorizing microbial agent comprising Providencia vermicola CM1, Pseudochrobactrum asaccharolyticum CM5, and Providencia sp. CM18 strains, with a fermentation broth ratio of 1:1:1, achieves synergistic deodorization by effectively removing NH3 and H2S with removal rates of nearly 80% and maintaining high ammonia removal rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional microbial deodorizing agents are used, then deodorization function is provided, but efficacy is inadequate and response is slow
Solution Approach 1:
The patent combines three deodorizing strains (Providencia vermicola CM1, Pseudochrobactrum asaccharolyticum CM5, and Providencia sp. CM18) into a composite microbial agent. This combination creates synergistic effects where the collective deodorization performance exceeds that of individual strains, achieving faster response and higher efficacy in removing odorous substances from livestock and poultry manure.
Solution Approach 2:
The invention develops a composite microbial agent containing multiple functional strains with different deodorization capabilities. Each strain contributes specific enzymatic activities targeting different odorous compounds, creating a composite system that comprehensively addresses the deodorization challenge with enhanced speed and effectiveness.
2Productivity
If traditional microbial agents are used, then deodorization is achieved, but sulfur removal rates are insufficient
Solution Approach 1:
The patent selects and combines strains with specific local functional qualities - each strain possesses distinct enzymatic capabilities tailored to degrade specific odorous compounds. Pseudochrobactrum asaccharolyticum CM5, for instance, contributes specialized sulfur-degrading enzymes, while the other strains provide complementary activities, creating a localized functional specialization that maximizes sulfur removal efficiency.
Solution Approach 2:
By merging three strains with complementary metabolic pathways, the composite agent achieves enhanced sulfur removal capability. The synergistic interaction between the strains allows for more comprehensive degradation of sulfur-containing compounds compared to single strains, improving both sulfur removal rate and overall deodorization stability.
3Object-affected harmful factors
If physical or chemical treatment methods are used, then odor control is achieved, but cost increases and secondary pollution occurs
Solution Approach 1:
The patent utilizes the natural metabolic activities of beneficial microorganisms to convert harmful odorous substances into beneficial products. The microbial strains degrade odorous compounds through enzymatic reactions, transforming harmful volatile sulfur compounds, ammonia, and other odors into harmless or beneficial substances like carbon dioxide, water, and stable organic matter, thereby eliminating secondary pollution risks associated with physical and chemical methods.
Solution Approach 2:
The microbial agent system is self-regulating and does not require external chemical additives or energy inputs beyond the natural substrate. The microorganisms utilize their own metabolic processes to degrade odors, with the system maintaining balance through natural microbial community interactions, avoiding the secondary pollution and cost issues inherent in physical and chemical treatment methods.
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 composite microbial agent provides stable and long-lasting deodorization, significantly improving sulfur removal rates and addressing the inefficiencies of traditional agents in livestock and poultry manure treatment.
Implementation Method 1
malodorous substances are degraded based mainly on the physiological metabolic activities of various beneficial microorganisms to produce carbon dioxide, water, inorganic salts, etc.
Implementation Method 2
NH3 is generated primarily due to the bacterial decomposition of livestock and poultry excreta and bedding materials
Implementation Method 3
H2S is produced primarily due to the degradation of sulfur-containing organic matters in fresh livestock and poultry manure by anaerobic microorganisms

AI summary
The present invention relates to a deodorizing strain, a deodorizing microbial agent, and use of the deodorizing strain and the deodorizing microbial agent. The deodorizing strain is selected from Providencia vermicola CM1, Pseudochrobactrum asaccharolyticum CM5, and Providencia sp. CM18 and exhibits a prominent deodorizing effect. The deodorizing microbial agent including the three deodorizing strains can improve a sulfur removal rate to nearly 80% while maintaining a high ammonia removal rate, which solves the problem that there are low sulfur removal rates in previous studies. Moreover, the deodorizing microbial agent can be easily applied with a low cost, which effectively addresses the issue that the traditional deodorizing microbial agent exhibits inadequate efficacy and slow response when used in the traditional stacking and composting processes for livestock and poultry manure and household waste.
