Growth promotion testing (GPT) is central to this.
Just before The supply of substantial-good quality reference components, growth promotion testing was typically performed by plating a serial diluted microorganism suspension on both a whole new along with a Earlier released media batch to match recoveries. This method proved hard in getting precise outcomes
“No rigid prerequisite was intentionally presented In this particular chapter because the test is qualitative, not quantitative. You could outline the comparability criterion by yourself. One example is, colony size at the shortest incubation time prescribed.”
