Integrating taxonomic and phenotypic information through FISH-enhanced flow cytometry for microbial community...

Area of Science:

• Microbiology
• Ecology
• Biotechnology

Background:

• Microbial communities are vital for ecosystem health.
• Understanding microbial dynamics requires integrating phenotypic and taxonomic data.
• Flow cytometry offers high-throughput analysis of microbial populations.

Purpose of the Study:

• To integrate taxonomic information into flow cytometry-based microbial fingerprints using fluorescence in situ hybridization (FISH).
• To explore the versatility of this combined approach in diverse microbial ecosystems.
• To enhance the characterization of microbial community dynamics.

Main Methods:

• Single-cell level taxonomic profiling using FISH combined with flow cytometry.
• Analysis of marine bacteria in plastic biodegradation and a simulated human gut microbiome.
• Beta diversity analysis and 16S rRNA gene sequencing for validation.
• Development of a predictive algorithm for sample classification.

Main Results:

• FISH implementation in flow cytometry provides single-cell taxonomic resolution.
• The combined approach enhances the distinction between phenotypically similar microbial communities.
• Successfully monitored microbial community dynamics in marine and gut environments.
• Validated the method's ability to track specific taxonomic groups over time.

Conclusions:

• Integrating FISH with flow cytometry significantly enriches microbial community analysis.
• This method offers a powerful tool for detailed ecological and biotechnological studies.
• The approach facilitates a more comprehensive understanding of microbial ecosystem functions and changes.
