Accurate yeast identification is crucial due to pathogenic and biotechnological species. This review covers molecular techniques like Pulsed Field Gel Electrophoresis (PFGE) and PCR-based methods for precise microbial identification.
Area of Science:
- Microbiology
- Molecular Biology
- Biotechnology
Background:
- Yeasts significantly impact human life, encompassing both pathogenic and industrially relevant species.
- Accurate identification of yeast isolates is essential for managing diseases and harnessing biotechnological potential.
Purpose of the Study:
- To review modern molecular techniques for accurate yeast identification.
- To highlight how these methods complement traditional taxonomic approaches.
Main Methods:
- Pulsed Field Gel Electrophoresis (PFGE) for electrokaryotyping.
- Guanine-cytosine content estimation.
- Polymerase Chain Reaction (PCR) based methods: Random Amplified Polymorphic DNA (RAPD), Universally Primed PCR (UP-PCR), Multilocus Sequence Typing (MLST).
- Mitochondrial DNA (mtDNA) and ribosomal DNA (rDNA) homology studies.
Main Results:
- Molecular techniques offer high resolution for differentiating yeast strains.
- These methods provide objective and reproducible data for identification.
- Integration of molecular data with phenotypic characterization enables polyphasic taxonomy.
Conclusions:
- Advanced molecular techniques are indispensable for accurate yeast identification.
