To produce enzyme in large quantity, equipment required are bioreactors. Large scale production involves use of bioreactors. Note: In 1990, Anderson and Schwarz licensed patents for the rotating wall bioreactor technology and founded Synthecon Inc. in Houston, Texas, to commercialize the device.

1. Bioreactors are used for small-scale production of enzymes.
2. Bioreactors are used for large-scale production of enzymes.
3. Bioreactors are used for the production of antibiotics only.
4. Bioreactors are used for the production of vaccines only.

Correct answer: Bioreactors are used for large-scale production of enzymes.

Solution

Bioreactors provide controlled conditions for growing cells or microbes so they can produce enzymes efficiently on an industrial scale. The prompt explicitly states that large-scale production uses bioreactors, matching the correct option.
