![]() Serial dilution is used in microbiology to estimate the concentration or number of cells/organisms in a sample to obtain an incubated plate with an easily countable number of colonies. ![]() Why are serial dilutions important in microbiology? Preparing a series of calibration standards by this method reduces the amount of required time. Which of the following is an advantage of serial dilution method?Įasier and Faster Preparation of Calibration Standards The errors introduced with each successive dilution drops proportionately with the solution concentration. Bacteria counted on plate counts are referred to as colony forming units as a single cell or a clump of bacterial cells can lead to a colony which contains many cells. What are the disadvantages of yeast serial dilution agar plate procedure?ĭisadvantage is that, it is time consuming and expensive as one needs media and other conditions need to be maintained. The result is that the highest dilutions will have the most inaccurate results. With each sequential serial dilution step, transfer inaccuracies lead to less accurate and less precise dispensing. ![]() The first is error propagation across columns or rows. Serial dilution processes face two major challenges. What is the main disadvantage of the serial dilution technique? ![]()
