Answer 1

Answer: (A)

Is a type of closed system

Batch fermentation is a type of closed-culture fermentation where the sterile nutrient medium is taken and inoculated with appropriate microorganisms and is left for a certain period of time to allow growth in the fermentor. Nothing is added or removed from the fermentor during the process. The product is separated at the end.

So, the correct answer is 'Is a type of closed system'.
