Answer:
Phenotypic approach for bacterial identification
Explanation:
Bacterial identification can be done by conventional methods, which are based on phenotypical characteristics. These methods are much affordable and reasonable.
<u>Phenotypical identification</u> is based on bacteria´s observable characteristics, such as their morphology, development, and biochemical/metabolic properties.
It is important to consider that these methods do not provide absolute certainty. They can only indicate the genera or species to which the bacteria under study may belong.
Some primary evidence is usually used for fast bacteria identification:
- Gram staining,
- morphology,
- growth at different media or different incubation atmospheres,
- glucose fermentation,
- spores production,
- motion,
- aerobiosis/anaerobiosis,
- among others.
Knowing that the bacteria in the exposed example was isolated and grown in culture, then Gram-stained and tested for biochemical reaction, we can assume that the approach for its identification is <u>phenotypic</u>.
