Function-Based Probes for Microbial Functional Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques for characterizing microbial communities in environmental microbiomes primarily focus on genome or transcriptome analysis, failing to distinguish between microbes based on their functional capabilities, such as cellulose degradation, chitin degradation, or toxin detection, which is essential for understanding metabolic activities and processes like biofuel production and bioremediation.
Innovation Solution
Development of function-based probes that selectively label and identify analytes, such as proteins and enzymes, in environmental samples based on specific functional activities, allowing for the enrichment and characterization of microbes with desired metabolic functions, including the use of probes with structures according to Formula VIII and kits comprising a substrate modified with functional groups for covalent binding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If genome or transcriptome analysis is used to characterize microbial communities, then genetic information can be obtained, but functional capabilities of microbes cannot be distinguished
Solution Approach 1:
The patent uses probe molecules as intermediaries that specifically bind to target analytes (enzymes, toxins, metabolites) in microbial communities. These probes carry detectable labels that enable identification and sorting of microbes based on their actual functional activities rather than genetic content alone.
Solution Approach 2:
The patent employs fluorescently labeled probes that emit detectable signals when bound to target analytes. This allows visual and instrumental detection of specific functional activities in microbial communities, enabling differentiation based on functional capabilities through fluorescence detection.
2Ease of operation
If FISH techniques are used for sorting microbes based on gene content, then genetic labeling is achieved, but sorting based on function is not possible
Solution Approach 1:
The patent develops a universal probe-based platform that can detect and sort microbes based on multiple different functional activities (cellulose degradation, chitin degradation, toxin detection, etc.). The same basic probe technology can be adapted to target various different analytes, providing multi-functional sorting capability.
Solution Approach 2:
The patent changes the detection parameter from genetic content (DNA/RNA) to functional activity by using probes that bind to active enzymes, toxins, or metabolites. This parameter change enables sorting based on actual functional capabilities rather than genetic potential.
3Measurement precision
If probes are used to label analytes based on function, then functional identification is achieved, but the complexity of probe design and application increases
Solution Approach 1:
The patent segments the probe system into distinct functional components: the probe molecule itself, the detectable label, and the target analyte. This segmentation allows for modular design and application, where different probes can be developed for different targets while using common detection methodologies.
