Question

Quizplus · Accepted Answer

Direct counts of microbial cells, counts of viable cells using colony growth procedures, and measurements of microbial biomass can all be used to estimate the number of microorganisms in a culture. Direct counts involve physically counting the number of cells using a microscope, while colony growth procedures involve diluting the sample and spreading it onto agar plates to count the number of colonies that form. Measurements of microbial biomass involve using various techniques to measure the amount of cellular material present in the sample, such as dry weight or turbidity measurements. Each of these methods has its own advantages and disadvantages, and the choice of which method to use depends on the specific needs and resources of the researcher.
