One particular exercise of selecting environmental isolates is usually to craze the recovered isolates, decide which microorganisms are probably the most predominant in the ability, after which use scientific rationale to choose which microbial isolates are appropriate to include in the growth promotion assay.

Utilizing the calculated concentrations of cfu per mL current At the beginning on the test, compute the change in log10 values with the concentration of cfu for each mL for every microorganism for the applicable test intervals, and Specific the adjustments when it comes to log reductions.

This technique will involve dropping the cells in a 10 µL aliquot on to the surface area of the agar plate (Miles and Misra 1938). When employed carefully, a whole six-fold dilution scheme is usually plated in an individual Petri dish and if read through early, the person drops can be utilized to yield estimates of the amount of CFU/mL in the problem suspension.
