Wash out in steady state fermentation occurs when
If the D is greater than the maximum specific growth rate (µmax), the result is washout, dX/dt becomes negative. The substrate concentration in the vessel can be accumulated.

See lessWhy a T-flask used in small-scale cell culture is incubated in a horizontal position?
Neck types T-flasks are mostly used for maintenance of cells, because a T-flask and its secure screw cap protect valuable stock cul- tures best against contamination. However, the narrow flask neck makes working with pipettes or cell scrapers difficult.

A bubble column reactor is basically a cylindrical vessel with a gas distributor at the bottom. The gas is sparged in the form of bubbles into either a liquid phase or a liquid–solid suspension. These reactors are generally referred to as slurry bubble column reactors when a solid phase exists.

See lessWhich of the following is not correct for the Monod model and the Michaelis Menten Model?
The Monod equation has the same form as the Michaelis–Menten equation, but differs in that it is empirical while the latter is based on theoretical considerations. The Monod equation is commonly used in environmental engineering. For example, it is used in the activated sludge model for sewage treatRead more

See lessFrom which mineral is radium obtained?
The correct answer is Pitchblende. Marie and Pierre Curie, Polish and French chemists, discovered radium in 1898. The discovery came from the study of pitchblende (a type of uranium ore) found in Bohemia (today's Czech Republic). The uranium was removed from the ore and the remains were found to stiRead more
The correct answer is Pitchblende. Marie and Pierre Curie, Polish and French chemists, discovered radium in 1898. The discovery came from the study of pitchblende (a type of uranium ore) found in Bohemia (today’s Czech Republic). The uranium was removed from the ore and the remains were found to still be radioactive.
See lessWhich of the following are the ingredients of gun metal?
Gun metal, also known as red brass in the United States, is a type of bronze – an alloy of copper, tin, and zinc. Proportions vary but 88% copper, 8–10% tin, and 2–4% zinc is an approximation.
