Study Notes
Microbiology Laboratory Techniques and Methods
- Individual bacterial species need to be isolated before they can be studied
- Microbes need to be grown under artificial conditions
- Aseptic technique is crucial to prevent contamination during handling of microbes
- Sterile growth media is required before handling and growing microbes
- Bacteria are grown in a medium containing nutrients, which can be liquid or solid
- Common methods of sterilizing bacterial growth media include boiling, autoclaving, and dry heat
- The five I’s of handling microorganisms are Innoculation, Incubation, Isolation, Inspection, and Identification
- Nutrient agar provides a surface for colonies to develop, allowing the examination of colony morphology
- Single colony purification is essential to obtain pure cultures from an isolation plate
- Microorganisms are grown in an incubator to provide optimal temperature and gas content
- The ability to grow microbes in pure form is essential for their study, and the nutrients required to grow bacteria in a medium vary depending on the bacterial species
- Disposal of cultures can be done through physical methods such as heat, radiation, and chemical sterilization, or through disinfection methods like pasteurization and the use of antiseptics and disinfectants
