Which technique would be used to estimate the concentration of Escherichia coli in a wastewater sample?
A) agar dilution tube method
B) laser tweezers method
C) cell tagging using GFP method
D) most probable number (MPN) method

Question

Quizplus · Accepted Answer

The most probable number (MPN) method is a statistical method used to estimate the concentration of bacteria in a liquid sample, such as wastewater. This method involves serial dilutions of the sample and inoculation into multiple tubes or wells containing media that will support bacterial growth. The number of positive and negative results are then used to calculate the MPN of the sample.
