![]() Serial Dilution Lab Conclusion Serial Dilution OfSerial Dilution Lab Conclusion Series Of DilutionsIn previous blogs it is seen that these minuscule microorganisms stake their claim on whatever they see fit (so long as the right environmental factors comply) so how is it that biologists are able to separate them so that they may grow an individual microorganism and study it or even count it That is easy (ok its rather time-consuming but worth all the effort) by serial dilution of course Serial dilution is a series of dilutions, usually twofold or tenfold, used to determine the titer or concentration of a substance in a solution. Once an organism has been diluted out and allowed proper incubation time, this is when one can be counted. The way in which this experiment will ask you to count colonies will be by way of the naked eye. Plates that are suitable for counting should contain no less than 30 or no more than 300 colonies. In the below experiment you will be taken through just how to go about serial dilution of the specified microorganism and from there after proper incubation time be given the ratio on just how to count the number of colonies present. Cool the molten agar tubes and maintain in the water bath at 45 degrees Celsius. The culture has been diluted 10,000 times (1-10,000 dilution). The culture has been diluted 100,000 times (1-100,000 dilution). Return the pipette to Tube 6 and transfer 0.1 mL to Plate 2A. Return the pipette to Tube 6 and transfer 1 mL to Tube 7. The culture has been diluted 1,000,000 times (1-1,000,000 dilution). Return the pipette to Tube 7 and transfer 0.1mL to Plate 3A. Return the pipette to Tube 7 and transfer 1 mL to Tube 8. The culture has been diluted 10,000,000 times (1-10,000,000). Remove a tube from the water bath and wipe the outside surface dry with a paper towel. Using the pour-plate technique, pour the agar into Plate 1A rotating the plate gently to ensure uniform distribution of the cells in the medium. Statistically valid plate counts are only obtained from bacterial cell dilutions that yield between 30 and 300 colonies. Plates with more that 300 colonies cannot be counted and are designated as too numerous to count-TNTC; plates with fewer than 30 colonies are designated as too few to count-TFTC. Remember to count all subsurface as well as surface colonies. With each dilution, a reduced number of colonies was observed (175, 50, and 1 for plates 1A, 2A, and 3A, respectively). The reduced counts between plates 1A and 2A were expected, and consistent with the regimen. Plate 3A produced only 1 colony, which actual renders it to few to count. The numbers of colonies on plates 1B, 2B, and 3B were too many to count despite the dilution. Since several plates produced colonies too many to count, the resulting averages are probably meaningless. Serial dilution is a method intended to reduce the numbers of colonies to a range between 30 and 300; two (2) of the six (6) plates we produced exhibited counts within the targeted range. It should be noted that some level of dilution was achieved as demonstrated with colony counts of 175 and 50 on plates 1A and 2A, respectively.). Inoculation and incubation were achieved as evidenced by colonies too numerous to count.
