C)serial dilution method.
D)MPN method.

Question

Quizplus · Accepted Answer

The streak-plate method is the simplest technique for isolating bacteria in growth media. It involves spreading a small amount of bacterial culture over the surface of an agar plate in a pattern that allows for the separation of individual colonies. This method is effective for obtaining pure cultures of bacteria and is commonly used in microbiology laboratories. The pour-plate method involves diluting the bacterial culture in liquid media before pouring onto agar plates, and the serial dilution method involves diluting the bacterial culture in a series of controlled steps to obtain a viable count. The MPN method is a statistical method used to estimate the number of bacteria in a sample.
