Growth promotion testing (GPT) is central to this.
You must utilize the strains which can be cited During this chapter, or equal strains from other culture collections. One example is, if Pseudomonas aeruginosa ATCC 9027 is indicated, you need to use this strain or strains from other tradition collections professing equivalence to ATCC 9027.
