A bacterial culture can be kept in the log phase of growth indefinitely with the help of a
A) incubator
B) chemostat
C) spectrophotometer
D) colony counter

Question

Quizplus · Accepted Answer

A chemostat is a device that maintains a continuous culture of bacteria by providing a constant supply of nutrients and simultaneously removing waste products. It is a type of bioreactor that allows for prolonged growth of bacteria in the log phase, as long as the culture is maintained properly. An incubator is a device used to provide optimal growth conditions for bacterial cultures, but it cannot maintain the log phase indefinitely. Spectrophotometers and colony counters are tools used to measure bacterial growth, but they cannot maintain the log phase of growth indefinitely.
