Fermentation Reactors MCQs

The growth of an organism on glucose is described by the following Monod model parameters: μm = 0.5 h-1 and Ks =0.1 g.l-1, if the concentration of glucose in the feed is 10 g.l-1 and the dilution rate is set to 0.4 h-1, then the steady state concentration of glucose in the effluent will be

A continuous reactor at steady state contains 0.04 g.l-1 of biomass and 0.02 g.l-1 of phenol. The feed contained 0.1 g.l-1 of phenol. The biomass yield would be

A culture system with constant environmental conditions maintained through continual provision of nutrient and removal of wastes is called __________ culture system.

The main reason for production of antibiotics in fed batch reactors is

Fed batch reactors is used to produce vinegar because

When a culture of fermenting yeast becomes metabolically uncoupled, ethanol

Mixing profiles closest to plug flow are observed in

On a glucose medium, the growth of an organism is characterized by the following Monod model and stoichiometric parameters μm = 0.3 h-1, Ks =0.05 g.l-1 and Yxs = 0.3 g.g-1 When this organism is grown in a 2 litre continuous on a medium containing 10 g.l-1 of glucose added at 1 l.h-1, the steady state concentration of biomass in the reactor will be

Unsteady state mass balance for dynamic model of continuous stirred tank reactor (CSTR) is
