Insert the resazurin sodium Answer, blend, and spot the medium in appropriate vessels that supply a ratio of floor to depth of medium such that not over the upper 50 percent of the medium has undergone a shade improve indicative of oxygen uptake at the end of the incubation time period. Sterilize employing a validated system. If the medium is stored, keep in a temperature involving 2

In combination with the compendial organisms required during the tests, addition of distinct microorganisms of fascination may very well be helpful when they are already recovered from earlier tests (e.g. a Sterility Test contaminant or maybe a Regular environmental checking isolate).
