On the determination of total number of colonies

dilution factor d refers to the dilution multiple of the sample when the total number of colonies is determined for the first time. In the determination of the total number of colonies, in order to get the appropriate number of colonies that can be counted, the sample is generally diluted. The dilution factor d represents the dilution multiple when diluting for the first time. By counting colonies on plates with different dilutions and combining with dilution factor D, the number of colonies in the sample can be finally calculated.

The total number of colonies in Meizheng Biological Group is relatively good. If you have any corresponding questions, you can consult their technology, and the service is still in place. I hope I can help you!
