Question

Which of the following statements is incorrect?

विकल्प

• Bio-reactors are used to produce small scale bacterial cultures.

• Bio-reactors have an agitator system, an oxygen delivery system and foam control system.

• A bio-reactor provides optimal growth conditions for achieving the desired product.

• Most commonly used bio-reactors are of stirring type.

Answer 1

Bio-reactors are used to produce small scale bacterial cultures.

Explanation:

Large amounts of bacterial cultures (between 100 and 1000 litres) could be treated using bio-reactors. Agitator, oxygen delivery, and foam control systems are features of bio-reactors. By offering ideal development conditions (temperature, pH, substrate, salts, vitamins, oxygen), a bioreactor creates the ideal environment for producing the intended product. Stirring bioreactors are the most widely utilised form.
