The growth of microbes is monitored above a specified length of time, commonly by measuring optical density or observing colony formation on agar plates.
Thus, the growth of numerous undesirable organisms is suppressed, whilst tentative identification of sought germs can be manufactured.
You must use the strains which have been cited During this chapter, or equivalent strains from other culture collections. For instance, if Pseudomonas aeruginosa ATCC 9027 is indicated, you ought to use this strain or strains from other lifestyle collections declaring equivalence to ATCC 9027. Other strains such as ATCC 14149 will not be acceptable.
