Study Notes
Microbiology Overview
- Scientific study of microorganisms, including bacteria, viruses, fungi, and protozoa.
- Aims to understand the biology, ecology, and genetic characteristics of these organisms.
Microorganisms with Membrane-Bound Organelles
- Eukaryotic microorganisms, such as fungi and protozoa, possess membrane-bound organelles (e.g., nucleus, mitochondria).
- These structures distinguish eukaryotes from prokaryotes, which do not have membrane-bound organelles.
Methods for Isolation and Identification
- Microbiologists rely on selective media and culture techniques for isolating and identifying microorganisms.
- Techniques include streak plating, enrichment cultures, and serial dilutions.
Molecular Biology Tools for Identification
- Tools such as polymerase chain reaction (PCR), DNA sequencing, and fluorescent in situ hybridization (FISH) are essential for bacterial identification.
- These molecular techniques allow for precise detection and characterization of microorganisms.
Cultivability of Microorganisms
- Approximately 1% of microorganisms present in common environments can be cultured in isolation using current techniques.
- This highlights the vast diversity of microorganisms that remain uncultured and unexplored.
