Solution Overview

Problem

Current probiotics in the feed industry primarily focus on maintaining gut health but lack effectiveness against specific pathogenic bacteria, such as Clostridium perfringens, Vibrio parahaemolyticus, and Salmonella, which cause diseases in animals and humans.

Innovation Solution

Bacillaene-producing bacteria, specifically Bacillus amyloliquefaciens DSM 33014, are used as probiotics that inhibit the growth of these pathogens, offering bile resistance, heat resistance, and anaerobic growth capabilities, and can be administered in feed or food products to enhance animal health and treat bacterial diseases.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional probiotics are used to maintain gut health, then gut microflora balance is improved, but effectiveness against specific pathogenic bacteria (Clostridium perfringens, Vibrio parahaemolyticus, Salmonella) is insufficient

Engineering Contradiction:
Improveeffectiveness against pathogensVSAvoidbroad-spectrum probiotic function
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent changes the chemical parameter of the probiotic by introducing bacillaene, a polyene macrolide antibiotic produced by Bacillus subtilis. This chemical modification enables the probiotic to specifically target and inhibit pathogenic bacteria (Clostridium perfringens, Vibrio parahaemolyticus, Salmonella) while maintaining gut health benefits, thus resolving the contradiction between reliability against pathogens and broad adaptability.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If antibiotic growth promotors are used to suppress pathogenic bacteria, then pathogen growth is inhibited, but the need for probiotics to fulfill additional functions (digestion help, gut health) becomes redundant

Engineering Contradiction:
Improvepathogen suppression capabilityVSAvoidmultiple probiotic functions
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent creates a multi-functional probiotic system where Bacillus subtilis performs multiple roles: (1) produces bacillaene to suppress pathogenic bacteria, (2) maintains gut health by influencing gut microflora positively, and (3) provides digestive assistance through bacterial enzymes. This single probiotic agent replaces the need for separate antibiotic growth promotors and functional probiotics, resolving the contradiction between pathogen suppression and versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If bacillaene-producing bacteria are used as probiotics, then pathogenic bacteria growth is inhibited, but the complexity of ensuring bile resistance, heat resistance, and anaerobic growth capabilities increases

Engineering Contradiction:
Improvepathogen inhibition effectivenessVSAvoidprobiotic strain requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs Bacillus subtilis, a naturally occurring bacterium that inherently produces bacillaene and possesses self-contained mechanisms for bile resistance, heat resistance, and anaerobic growth capability. The bacterium serves itself by naturally having these survival mechanisms built-in, eliminating the need for complex external interventions or modifications to meet probiotic requirements, thus resolving the contradiction between effectiveness and complexity.

Inventive Principle:
Principle #25Self-service
