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

#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.

In a continuous culture system (Chemostat), what happens if the dilution rate (D) exceeds the maximum specific growth rate (mumax) of the organism?

#Question id: 40197

#Applied Microbiology

Assertion (A): A turbidostat is most effective when operating at high dilution rates near the maximum specific growth rate (mumax}).

Reason (R): At low dilution rates, the chemostat is more stable because the concentration of the limiting nutrient is easier to control than turbidity

Read the following statements regarding Fed-Batch culture and choose the correct option.

Statement I: Fed-batch culture is ideal for producing secondary metabolites (like antibiotics) because it allows the culture to be maintained in the stationary phase for a prolonged period.

Statement II: In fed-batch culture, the volume of the culture broth remains constant throughout the fermentation process.
