There are actually reviews and worries about dissimilarities in these values attained applying distinctive sampling methods, media variability, and incubation temperatures.
Ahead of The provision of significant-top quality reference resources, growth promotion testing was normally executed by plating a serial diluted microorganism suspension on equally a completely new in addition to a previously unveiled media batch to check recoveries. This method proved complicated in acquiring precise success
