What are the advantages of using serial dilution in microbiology?
Posted January 9, 2024

Answer

There are various advantages of using serial dilution in microbiology. 

  • Serial dilution helps to gradually decrease a high concentrate cell culture to a more manageable and practical level. 
  • Counting the colonies obtained from these samples helps estimate the concentration of an unknown substance. 
  • The known concentration solution is measured just once. As the concentration decreases with each step, the error margin in each subsequent standard decreases significantly. 
  • Having evenly spaced standards enhances the reliability of the analysis results. 
  • This method is also advantageous when the calibration standards need to cover a wide range of concentrations.
