Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Lactobacillus mudanjiangensis strains are isolated and characterized, then novel cellulase enzyme with industrial applications is discovered, but comprehensive genomic characterization and strain utilization remain insufficient
Solution Approach 1:
The patent performs preliminary whole-genome sequencing and comprehensive characterization of L. mudanjiangensis strains before their industrial application. By sequencing the genomes of multiple strains (including type strain DSM 28402T and isolated strains AMBF197, AMBF209, AMBF249) and analyzing their genomic features, the patent establishes a foundational knowledge base that enables subsequent efficient utilization in various industrial applications, preventing information loss about their genomic characteristics.
2Loss of information
If multiple Lactobacillus mudanjiangensis strains are sequenced and characterized, then comprehensive genomic information is obtained, but the complexity of strain isolation and sequencing increases
Solution Approach 1:
The patent segments the characterization process into distinct manageable components: (1) isolation of strains from different sources (carrot juice fermentations), (2) whole-genome sequencing of each strain, (3) comparative genomics analysis focusing on specific genes (cellulase, pili, conjugation), and (4) functional validation. This segmentation allows systematic accumulation of genomic information across multiple strains while managing the complexity through structured analysis protocols.
Solution Approach 2:
The patent employs universal whole-genome sequencing approaches that simultaneously provide multiple types of information: genomic structure, gene content, GC content (42.7-43.1% for these strains), phylogenetic relationships, and functional gene identification. This multi-functional sequencing approach efficiently gathers comprehensive genomic data without requiring separate specialized analyses for each strain.
3Reliability
If the cellulase enzyme is isolated and characterized, then its enzymatic activity is confirmed, but its application across multiple industries requires further development
Solution Approach 1:
The patent extracts and identifies the cellulase gene (endoglucanase E1) from the L. mudanjiangensis genomes, separating the functional information from the whole organism. By isolating and characterizing this specific enzyme gene and its protein product, the patent confirms enzymatic activity while enabling independent development and application of the cellulase in various industries without requiring the entire bacterial strain for each application.
Solution Approach 2:
The patent analyzes and utilizes parameter changes in the cellulase enzyme's properties (optimal pH, temperature, substrate specificity) to adapt it for different industrial applications. By characterizing the enzyme's functional parameters and understanding its performance under different conditions, the patent enables the same cellulase to be effectively applied across diverse industries including food processing, textile, paper, and bioconversion, where different parameter conditions can be optimized.
