#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.

#Applied Microbiology

Assertion (A): Primers with high GC content generally have a higher melting temperature (Tm) than AT-rich primers of the same length.

Reason (R): Guanine and Cytosine are bonded by three hydrogen bonds, which require more energy to break than the two hydrogen bonds between Adenine and Thymine
