Thầy cô/ các bạn dịch giúp mình đoạn này với ! cảm ơn nhiều ạ !

Most Probable Number procedure is a statistical method based on diluting organisms to extinction, and evaluating whether a positive sign of the organism’s presence (such as color change in the medium or gas formation) appears in replicate tubes from a given dilution. As the calculations involved are very tedious, tables have been published that are specific to a particular MPN design. MPN is commonly used in soil analyses for such assays as pathogen detection and in wastewater analysis. The procedure is depicted in Figure 6-1.A dilution series is made much as for the culturable heterotrophic plate counts in the previous experiment. However, 5 tubes of media will each be inoculated with 1.0ml from each dilution suspension (step 2). The tubes must be incubated with sunlight or artificial growth lights. The MPN evaluation itself is simple and involves little more than counting the tubes that show a positive sign of growth (generally a green surface ring or film (pellicle)) and using the data in an MPN table along with soil dilution information. See the Calculation section for details.
