#Applied Microbiology

Assertion (A): The generation time is shortest during the exponential (log) phase.

Reason (R): In the exponential phase, bacteria are adapting to the environment and repairing cellular damage.

#Question id: 40193

#Applied Microbiology

Read the following statements:

Statement I: Obligate anaerobes cannot survive in the presence of oxygen because they lack the enzymes catalase and superoxide dismutase.

Statement II: Facultative anaerobes require oxygen for growth and cannot grow in its absence

#Question id: 40194

#Applied Microbiology

Assertion (A): Thermophiles can survive and reproduce at temperatures above 45°C.

Reason (R): Their enzymes and proteins contain more hydrogen bonds and salt bridges, making them heat stable.
