Answer: 4. Bio-reactors are used to produce small scale bacterial cultures.

Bioreactors are large vessels (hundreds to thousands of litres) for large-scale production of products. Small-scale cultures are made in flasks. So statement 4 is incorrect. The other statements correctly describe the stirred-tank design, the agitator, oxygen delivery and foam control, and the optimum growth conditions.
