Final Answer:
The genus Pseudomonas shows the characteristics of being Aerobic, Rod-shaped and Oxidase-positive. So the correct option are (a) Aerobic, (c) Rod-shaped and (d) Oxidase-positive
Step-by-step explanation:
Pseudomonas is a genus of bacteria known for its diverse metabolic capabilities and ubiquity in various environments. First and foremost, the correct characteristic is (a) Aerobic. Pseudomonas species are aerobic bacteria, meaning they require oxygen for their metabolic processes. This adaptation allows them to thrive in oxygen-rich environments.
Moving on to the next characteristic, (c) Rod-shaped, this refers to the bacteria's morphology. Pseudomonas bacteria typically have a rod-shaped or bacillus morphology. The shape of bacteria is an essential characteristic used in their classification and identification.
Lastly, (d) Oxidase-positive is another accurate descriptor. Pseudomonas species are oxidase-positive, meaning they produce the enzyme oxidase. This enzyme is involved in the oxidation of various substrates and is a crucial factor in differentiating bacterial species.
In summary, the characteristics that define the genus Pseudomonas are its preference for aerobic conditions, rod-shaped morphology, and the production of oxidase. These traits contribute to the adaptability and distinctive features of Pseudomonas bacteria in various ecological niches.. So the correct option are (a) Aerobic, (c) Rod-shaped and (d) Oxidase-positive
