How do you find unknown in microbiology?

Begin the process of identifying unknown bacteria by observing their physical characteristics, such as cell wall, shape and linkages. Use standard laboratory procedures, like cell staining, culturing and DNA sequencing to further narrow down your identification.

What are the steps to identify an unknown bacteria?

Various steps involved in the identification of unknown bacteria are:

  1. Isolation: The importance of this step is to isolate pure colonies of bacteria.
  2. Staining Reactions:
  3. Biochemical reactions:
  4. Indole test:
  5. Methyl Red Test:
  6. Voges Proskauer Test:
  7. Citrate Utilization Test:
  8. TSI:

How do you write an unknown microbiology report?

For example, instead of writing “I used a TSA agar plate to isolate my unknown,” it is customary to write, “A trypticase soy agar (TSA) plate was used to isolate the unknown.” It is also customary to write in the past tense for most of the report.

How do researchers identify unknown bacteria?

Biochemical Tests Used to Identify Microbes Some biochemical tests for microbial identification are quite simple. To test whether bacteria contain a catalase enzyme, a microbiologist drops hydrogen peroxide into a smear of bacteria on a microscope slide.

What are the main bacterial identification methods used to identify unknown bacteria samples?

Among the techniques we use are:

  • DNA sequencing – to identify bacteria, moulds and yeasts.
  • Riboprinter analysis – for bacterial identification and characterisation.
  • Repeat–based polymerase chain reaction – for assessing the similarity of microorganisms.
  • Rapid pathogen confirmation by polymerase chain reaction.

How do you write a lab report for microbiology?

A lab report differs from a paper in that it has defined sections. The sections required vary from laboratory to laboratory but the standard outline for most lab reports in the biological science include: title, your name, purpose of the experiment, methods, results, discussion and conclusion, references.
