Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains. Approximately...

Background:

  • Microbiome research has identified microbes linked to health and disease, but understanding their functional interactions remains challenging.
  • Current methods like 16S rRNA sequencing, metagenomics, and metabolomics struggle to resolve complex metabolic interactions within polymicrobial communities.
  • Metabolite exchange in polymicrobial communities significantly impacts bacterial traits, including virulence and antibiotic resistance, highlighting the need for advanced analytical approaches.

Purpose of the Study:

  • To review advances in metabolic modeling as a computational tool for predicting microbial metabolic capabilities and interactions.
  • To illustrate how metabolic modeling, combined with experimental approaches, can elucidate microbial community function.
  • To propose the integration of metabolic modeling with experimental work for advancing laboratory research and drug discovery.

Main Methods:

  • Review of the latest advances in metabolic modeling techniques.
  • Analysis of literature examples demonstrating the application of metabolic modeling in microbial ecology.
  • Integration of computational predictions with experimental validation.

Main Results:

  • Metabolic modeling offers a powerful approach to predict metabolic functions and interactions in microbial systems, from single species to complex communities.
  • Case studies demonstrate that combining metabolic modeling with experimental data enhances the understanding of microbial community dynamics.
  • This integrated approach can pinpoint microbial determinants influencing community function and host health.

Conclusions:

  • Metabolic modeling is essential for deciphering complex microbial metabolic interactions and community functions.
